Dredging Processes 1 Introduction

[Music] will be the discussion in this course will first the role you can see sunlight pictures and the course is part of the programme of your and dredging engineering sir you can see you that and what exec lee is of your and dredging engineering pico's many people yes reminded me of that or a guess hear sometimes here you see to tell what it's not and what it's not is transporting people of boots van aid to be the chordettes becomes micro pore technology so you have image chips with the purpose to transporting that mary and technology us so fischeri is not part of your engineering met almost everything else both by something something in oil and guess moritz dredging or something recovering sunken submarine it's all of your engineering some on the late is that indeed on people you will see in in order course is what whoowie new forest for exam who got it right student who star it is master thesis for and tidal current energy there is an area north of scotland war between the islands us very strong tidal currents toe meters three meters per second and they want to put YouTube turbines in that area and try to get energy fund and the cups problem is the installation of the whole system be cause you constantly lift box YouTube course yes in one direction or in the other direction but if you lift your three minutes per second current it's very difficult to install' Zantingh about the thief for the any way that the master thesis to find out how to deal with at yes what do you want to do in the price he co- overview of the price first that stood centuries do an introduction to know morning tent dirty wild soil mechanics and that as so Santing already this briefly in the introduction and of course big time will be worse than we who just wants white cent discount in the find be specific energy how it is the tap I that is important for all time of both the tango shell Judith new in box lectures the adhesive chain and what chain December 12 production and estimations so with all the theory views get how can you test with the production or the wide lashing vibration that Weiss whatever am Kees from region take over three lectures talking about sedimentation in hopper dredge is so dead lottery process of trailing suction hopper dredger and in general and jerry after a dual talk about breaching most people don't know exactly what breaching is with if you thick high and the word there the waltz will start collapsing and they actually use that to get production so you you you have some sort of suction mount and the bottom is constant Frisian handsome the soul and then be courgette steep slopes so and starts moving down and that way you can create production an exam of where they use that may be some of you may know if you will close to hereto Voorschoten now have Leek which is now the tour is Leek bed where he was a student this Leek this a tracklist this was farmland and becomes this they do they started making that Leek to get cent for the Prins Clausplein so part was a pipeline already the week of Voorschoten when the Prins Clausplein to get cent over the air and they just powder pipe into the ground tailpiece and have recently and then the Leek car with the wheelie bins piglets so that's becomes Kees wants to do and then the boot Lexion Jerry tent he plants Samsung ex adjust or the exams and you can aas questions yes floated standstill in you don't understand you channel becomes to the fields of interest of a program and now will show you many pictures today and many questions in the other lectures where we the board and found it structures would you have purchase that agrees to the sea floor this from her specialized asians it can also be inactive regions becomes in arctic regions is she problem picos the ice in this picture it looks like the eis is not moving bed in reality the eis is constantly moving one way of movement is picos of the eu rotation that salsa lessons rotation with respect to a planets that one reason why it's moving and the other reason is currence letter and the the ice and want to take the eyes with them and that also makes guys doing zowat have an atmosphere the ice is constantly lee moving a gangster platform and wants to to push the platform be so working in the arctic could be very difficult by the know is lunchbox bottom found its purchase with us' nexum and six hundred meters becomes adapt easily the limit ez about for them became that who could go up to six and a new that well point what you see here is of your wind farms and if you look at the policy of your government they want to spend a lot of money on renewables and one of the Rio forests is wind energy so they want to put them in the sea the cross if you could olders wind mails outlined yes I that comes to be put in there because the image youtube wind farms up to certain word there the app you can use bottom found it wind farms well around year 2000 and daily sided how you already so because you want you deeper becomes there in deep words you cannot use bottom found it anymore so the year along king floating wind mail sexy and that give some new challenges perhaps you have boxes wind mails something wind mill not of electrical the cable yes I if you like to use the electricity company you of their gust wind by means in a kind of area in a small area you don't want one their turn cables to go to shore so in the area of ​​that wind farm you have your thick wishes and that's part of this course wooden thick trenches jef the thick wishes conecto box cables somewhere in the wind farm week already that the many full 2 ​​roll doos kegels come together and then you make one you cable like this ons you're so that's the way to dit that you not the ladder french english you can not leave doos gables under sier floor gives you do this and if you fischeri ship marries the nets and and all those things and I want dragons the cable the cable will break and that's it and by the way so are with me have a view app pipelines the and floating yeah since most of the easy morale has already been found anyway already is already very deadly find ons your wonderland and it's all that we've hain't in in the shallow becomes there had to wit hazard ibn found online games by joy who has the go-to deep motors and currently who go up to 3000 meters of word adapt and that means or your constructions heb to the floating so this is so cool tlp team chooses and sport engine leak platforms and doos it looks like dr gables was in fact with her tube the year and by youtube tension so first what d do is dheepan this platform feel smoother something like that family then they mount cars what you for pikes becomes have you want to cold and end end I am the word keeps so the platform wants to go app and then you could all those spice in the region tension lord you not very strong anchors in the ground to holds box forces so that's how this is anchor tin that's why you call it the engine leak platform this is an FPSO what you them floating products and storage facility the already earlier chance of lord to this FPSO of of the sea floor white riser up store temporary and f here in the FPSO so discover you can't see complete chemical factory so do already push lot of pre-processing on top of the FPSO store the royal and then once a week the shuttle tanker like this will drop by den pol the war in the shuttle tanker and the shuttle tanker will bring your own way the list built-in and FPSO bit cannot see it om this picture it hasn't so cool tablet and the terret is vertical bering picos what happens if you have storm of my shirt and direction the shipments to move in der direction so the cake is vertical bering and that's connect this becomes only studies i floor and the she can rotate and room dead bering all the unwillingness coming into that bering would you don't have problem becomes the travelers and the eye connections in the course to floating you get more the tales to subscribe' of ships and then we hef dredging bewitching is the typical german belgium profession the inholland wie hef tool big companies and in belgium also their use to be many more b'day murch at least and tilde rare just to left in holland and toe in belgium deco them the big for those chose and dl speed s by the way such a of ranch company's everybody you speak dutch the big for ministers the free world make it and the free world market is the market where you can try to get it jou there like so the not free world market week was in some countries they use protectionism and you can never get it yet they're dose for companies df sixty-two 17 percent of the free world market worldwide so the year quite big country that It is not free in the United States, and its own strength lies in the decor. It is like having a free market economy, which they have had for a long time in the US. Also, green technology engineers should know about that. Loris Colt, the De Jones Act, and De Jones really tell you that chips were built on the keel, and the keel is the bottom of the ship where the keel was built. In the US, they are not allowed to work in the US, so they have problems with themselves. The course of this protectionism is much more expensive to build chips in the US. If you want to build ships in the US, the problem is the package price is about 15 percent higher than in the free market. Yes, even the Dutch company Bildtse says that you can go to Dubai to create a ship, and look for the cheapest place is to build the hull and then the complete machinery. For me, you see, hear, and that way you can combine all the benefits of the free market in the US. You understand that, do you understand? So, it is possible to build in the US, and yes, that means a brand and dredging company like Sarnath are competitive on the world market. The course is that there are ships already. fifty percent more expensive so you can not really compiet the oil place where they work internationally is in the Middle East and I'm not sure whether that by free market or by compensation and orders of the will for you never know they were not tell you where what are you doing here hopper dredge and in this case hotel beautifully built athletes you see the hopper dredger a Boeing hotel seemed to be being built deep sea mining he our webshop extra flights about deep-sea mining this is one of the bitterest [ __ ] gracious with lord the front [ __ ] there the and this is the vice for trench and gables in the North Sea but who has many more devices to the field of trashy sapsie sup see and in fact deep-sea mining is part of sapsie since wego to deeper and deeper wolters what you he with that and reading at the service is subject to storms and their games and something like that variphone there you experience polishing santing and the service wall decor they know that for a long time so and riehting signs blood test floor they will put under see for many people twingo ii of give never up feel that means through also company duels despair and this kind of thing became all comes out but in fact did will many holes maybe in one field df twente your dirty holes wealth and free call them and although swells yes like wit wit the of your wind catch with electricity gables and who well the pipeline wit war guess a bit don't want twenty actor those pipelines go into the service and that makes the system to phone double so what doedee doedee connect all dead pipelines and to see floor met control units to control flow and everything and then they connect at one point which they go and many feels and of that many feels everything will go wit riser toe the fpso or whatever by the way wit now there is also the course ons subsea engineering van mr prodi die tail the right ds fireshine now and then you can learn much more about everything that happens session floor yes well what is driving the market and i'm talking about the home market for of your and dredging engineering well toe tail wit and picture samsung blow or lost the world this is container true fine to that is was beam trash does and you can see is constantly increasing so ever hear windmill containers who what thicker chips and such townspeople they hey what a m-use to offer bikker sport in the world and now it's one of the charlie sport is and that the pretty well it's not be kast shiny sport sarnath competitive how the what there then in fact this playwater them with more containers and marloes in antwerp would be one of the bigger sports that would really be comes editor or him work for ex offer the if you have lead of container activity in china in singapore and malaysia then that's only does for rotterdam it means we get more chips the sector why is that important for first there falls in the the total to put of containers is increasing it means you not big reports and f you may know inholland wii just how you her finnen went so tweede maasvlakte which is an extension of rotterdam port into the sea to make it the biggen poort that to make the poort bikker first folio nederlof sent to create that extra poort the centcom somewhere of the notion and it is the dredging company bedsupply So, end up like this: the dredging company views remake talent and then another contractor finishes HDD, make it or IO port with the infrastructure in the grime, ten, all the electricity and for systems, and become a bucket with another thing, is that PICs? Who has more containers? They like to build bigger chip- bicker ships that can contain many more containers at once. Do you have this? The volume of boxes will increase, and that means you need to deepen the entrance channels to your port, like oil deeper and train sets channels, dazzle so good for speakers, jets, dredging. You can't hope for gadgets, too, deep box channels. If you look at the list and fear partly advice about that, if you look at the list of biggest ports in the world and biggest container port, you will not find any US port discovered list, and one of the reasons is that ports have such a way, and who already knew I the US is one country with a white-collar government. Well, basically it's not every station is still quite independent. We have the national regulations and within estates and free cities of county is quite independent. That means that in the US, all those local ports are competing with each other, but there is no fed police to image what youtube container port would effect in a notice that the biggest containerships can not go there be cause they don't have any more depth deep in af that in europe and work and work rotterdam they can handle doos chips this is an x ​​number of singapore singapore is one of the bitterest container terminals you can see helbig it is and what you can as an otys has your look turn your hartley sea and the people there are still people the johan grythyttan why is that well even container chance of my [ __ ] the goal of to a river a car with I that did vehicle and those circles kind of offer truck do do later that have driver thea completely control at computer samsam central place so dme control container terminals wit out people they found that there is only one thing the machines cannot to and that one thing is that containers haar connect-it and and the you just have steele pin to the containers to connect and to get those spin zout you can do that at machine juni the big member to to get those spin zout specially if you have chips coming van de akte I often ferry a box of pins her frozen door lock of ice and there is no machine that can do that auto with preferably so there quietly people to to disconnect the containers from each other pray for the rest and reading is for you to with I am energy this is not the latest picture but with this picture i made the before the economic crisis there are some small differences picos of the crisis met not to make one of the interesting things will first of all if you look at the red line that sorry well everybody knows men nice dust the energy chance of royal blood and this purple line is cool and many people and especially in the west they feel like i do n't you go anymore uwe naam was jong we use the goal for the heating system and then wie get leden week that the central heating system with coal is still use too late and you can see something increasing for for the big power plants so in many countries they still use the coal for the big power plants and they can do it very efficient and very clean something like the dirty way of getting energy like it used to be will you thank you that fc2 a like wie it twenty years ago and after that nobody ever talked about it anymore het so kool can be used are clean and it's still one of the biggest sources of energy with what you can see we the blue line is natural game is up coming and more and more who wants youse natural care and by the way to the forty years ago natural guess was a byproduct and rolled company's just felt yes is something is something this charred zoey jazz burn it and you all the platform they youtube flame picolit flooring and they just burnt all the natural glass and they didn't use it until they discovered leather that you can or sell it and make money for natural care and now l angie is one of the biggest and providers of energy sir you see the nuclear ijn and other wie new bos effect whether it it increasingly table or something increasing the tenth youtube lee to policy of governments even government stimulates using renewables it will increase one of the problems of course is that if you do something you you can do it perfectly in the bidding yes it's like if you want to use this fun time of engine together but I will be the Wankel engine ever in the beginning it's never competitive we The existing commercial engines, Wiko's, the standard engines are the perfect. Yeah, you can't really improve it, and much more. That's your tail, and you're the dead end. Yeah, you're still left to go to that point of making it more perfect, and that's what you have with how you get new Wolf-like solar cells, wind energy, fuel cells. Probably in North Twente, here's van now. It can do it. The competitive right now. It's not yet, so governance lifts up advice on development, and then I will hope that one day I want that competitive big oil, and guess who can use more clean sources of energy? Then your soul is gone. Where do they actually use the energy? But this picture is no longer the cause. Yeah, hi, just a new picture, and what you can see here is the enormous synchronization of energy in the USA. Over the last dirty days, well, here in 2007, this stops like this. The peak did you see here is already too high in 2007 in the US. The one in Queer steps in, and now something weirder, stable bed. And you can see Western Europe was already quite stable. Bigozian busy with saving energy for a long time. time you can see India and China' Lord increasing a lot and getting hurt from [ __ ] who is with China' the the sharks speak and China' is is already at the same level even the us while that sludge ik in small you have one point five million people something like that in America 300 million so shine s5 times as much and that means of everybody good use the same amount of energy is in the us then the the hajus bar ruby ​​5 thumbs hi es in the us and let's hope they will take care of the energy je little bit better otherwise wie er één tribble it becomes you can see of the in in box that is on human is that the month of energy so the month of of Glasgow is still increasing and that's one of the reasons that the oil and gas industry inholland the of your industry is still booming business we had conf in November the the of your energy 2012 he was there the opening and in fact the of your company's and also the dredging company details for more scilt staaf en auto die ouwe boy who is heroin 100 master student in her program is 13 or for you don't do more and then one of the stereo set where we could use to may be treat ice s many engineers in our business becomes blood for you with that and until now from murano we don't have any student who didn't have job at graduation day yeah everybody hasn't shop usually in the company where your goal your master thesis it it can also be another company is like that there is plenty of work there just your counter where so the all come from where is it going to you can see that there are you transport of of some times by pipeline mean like ferry morning by ship the chips not feverish and and has you have more all to be transported now not nice ship you not thick gate does something like that for the million technology industry is does for the dredging industry to make more gate yeah it does for the hal industry and that will be so increasing in the energy like eggs that showed you one of the king's is Arctic Engineering and this has just inside the news of Shell Oil HDD Greenpeace protests they started filling in the Arctic Dawn of the tanks the public doesn't know but you should know she will not stare sexual activity we the old research without investing theory that in west it may be three trillion euros in in Westgate content idiot white Arctic and warming something like that well the matter the bed to Devonian sambal York and you stand drilling for me in the Arctic Daily Grape and this and company's live Shell Exon BPD cannot have situation where they and arguments on the heaviest in the Arctic Picards the ant of getting off of the Arctic and then the hope public opinion will be you know this box companies will prepare well but still right now they passport drilling in the Arctic and one what is one of the problems well what you can see here if you have eyes works and those are just small eyeworks my ten percent of the iceberg is and the words that means you have those pi x and the words Rendo speaks can be fifty-fifty meters now it's not just 5 meters the public sixty meters that means has your harbor water depth of fifteen meters and and now heaven iceberg of sixteen meters and the iceberg is floating yes the shirt and moment this wants it so i floor and make the range indices floor is there that point there is the pipeline like you can see here and and this iceberg must this the pipeline it will just cut will the pipeline and you gather youth oil spill otherwise that floor nobody wants just like that what do you have to do how you have your thick wishes yes sorry he has to do trainers in the ornament floor and barry the pipeline so deep that how your show the eyes work will never hear it what I am doing now this in enormous regions are who has your project of ankles and of fishery times and so of who has there may be up to 5 meters or is it dept to bury pipelines and to to make it safe who this friday how have I know you we it how is his graduation is to actively trencin and the fusting hiding hist for is teasers is added in westgate keeps deep her box grange's that you get from box picolet ice power by the way how the paar box trenches here found out of research did this in the post that it can be up to 6 7 meters deep what that means the pipeline he stabilo bit cannot say okay the eyes work is 7 meters out the pipe the tab of the pipeline the 7 meters just safely chose I this size burke is moving to this file this indeed those formed soul and that means you heft be may be one art tool mieters bilo dit level not to hälfte des formations that you'll get van de sovjets moving met de ice zo in in our opinion eefje doerak tikt ranching jungsheft' to make twence u zult het en meters diep nou deprobleem of course is is normaal idee wil maken 4 shaped trench beetje deeper het is de bingerden cross section of de fichier pen juni terim of mars ooit zo smal biko zin in de tactics region df hart clay we herdenking of bloks cat and then de mount of material your email of is proportional to adapt of de kat wat hier seks elite weet u weet iemand of je hebben search shock box kut let's say to meter sway tent en mieters diep en de pipelay in vessel of als isis kan enorm heerema en de pijp is medisch-ethisch centimeter vind die hem het er ja de flip en de service is moving zo de hoop pipe is moving eh little bit that means is de pipe is partly in de transcend en movin up to the ship dit wil constant leave it de site of de trench en derde tranche michael apps and you have problems because i've want zit collapse is you can stare already over knows so who he well on the the wise to putin the little train that can move we the grip toe protect the sites of the train and then how the pipeline in the trends in a safe way so is your interest this is take shield pijnenborg and out think ie hessische presentation to clock friday of what there remember by the way they can use hopper dredge is this is a heaping the way for measurement trenches like that and heaping through neatly white one week arm could well on tuan their the twenty-one 113 mieters of becomes adapt and then population even look at the world population in many people regions nat in in europe may be put like here in china move people live more the see master the activity the industrial activity is down the see if you look at your pen whites completely wet java you creative see here something saves it in chip and chip and is a can you again the ladder mountains and down the see you have such flat areas des were people if des joyful the activity we agree with this if you want to increase your point or make a new airport or whatever there is no more space any more of you do to Singapore Singapore's island Thailand is full no more space and Singapore he Samson tension Whitman lazy is so thick and the ex tent in the door action of Malaysia so becomes can they do Waldo meeting you can goal is reclaim land from the sea and go into the sea becomes Kees ow stealth looked from Ree is the price you pay for land that you week line of the c has the motor is not too deep is about to 100 euros per square meter do you have net ground that you can use imagination building cent such a like in Delft you pay up to two 1000 euros per meter and lessons in Holland offers Quinn want 1000 and 2000 so e-bike and reclaim land from the sea it's much cheaper than buying land somber in the country so at Xtend the country into the sea something cheaper and that's one of the reasons why dredging companies to use land reclamation project and in fact xtend kunt rise into the sea this is a picture of Hong Kong airport check lap kok this here is the airport and it used to be an island with the mountain wild and use of dynamite first to blow limbs the the the surroundings of the island' on at night smoothly put your apps on bass and so you fill it up white the skirt get of the month and and then with hopper dredge is you gather ladder sent to make the whole area flat the policy of this was tooting first rolled also airport in Hong Kong was a little bit dangers and if you want to see why you he the mountain rich he you have the city of Hong Kong and here is there and the airport was like this so in the middle of the city he Jungsheft' mountains so I just a there square must live I mean be alive like this and I slept in there at that time so the square is a riving restemming ninety greater than flight to the landing strip with one you fly to the landing strip tom boot site itself you look out the window you feel you can she can switch such a Charlie's standing in the high living in box hi building swinden stanton therefore and that is so close you can see what he eats and that was very dangerous because if you have storm and wind and so on the airplane is just separating a little bit of the direction you could get crash before that little path down moment in this direction with them like a up goodbye chose the best way to make the square that horse is the gantz the wind and in this case you cannot use in the pension so the wind came from bad so they decided to make you airport 15 miles outsite or of come on an island so the hope there gate is so often ow of the urban areas that people have no problem' white airplanes anymore that also means you not the image and hi words with highway and their souls or so tip 2 going to Hong Kong and in fact if you travel access kom you will see that your suitcase is such a your love it can be transported all the widow supplies station in the center of or car with the client has hotel and eating and just pick up and if you have to check if you check in it is there playstation there you the deliver all your luggage and in amsterdam je pikken dapper ghent and you don't have to carey everything to the airport and level of druppels so theory organice everything well but you can imagine this is ladder dredging works a lot of land reclamation as imagination dead and something is a youtube infrastructural project so that's one of the teams participating another picture here is singapore ahoy title singapore is feel and effect in singapore you would like to schepper knows urban areas with have industry speciali the chemical industry because now mix it was mixed singapore didn't have any line to anymore just about canday do well in the fond of singapore in those areas that we love small island if you connect do silence and that's what you can see here did connect also silence who claim lent and poll the oil and gas industry and chemical industry undead discovered new land that we your take it out of the city so so this here is a nice clean and wire coin this will so much 7 tony problem here was that in the main heating or Singapore there was no cent research floor and the more they already use and reading wild and you can go to the northern Tunisia we they didn't this permission so push and add the sauce Indonesia to get the cent and that it of complications picos yes in Indonesia if you don't have the right permissions' and has you don't know the right people dollar in trouble so infects pies the project that was in 2000 2000 won den berg and 3d for get to gripes om body and everytime and the chips came back to get cent that I was the tour 100 miles or so thick was the border so that the certain point the Indonesian government said hey you didn't went' to customs wanted ship so now the stevedores and what the ship was nat airs bedeep how this around the ankle and the ship has therefore we couple 4th and it costs Olaf Tribbles so is if you in which this international business what there something war guess of dredging jungsheft' to learn something about the habits in other countries the culture in other countries picos we year eefje contair white white the rest of the world holland is still a little bit heffen who then drink anyway look at the current government but anyway in general it is and in many countries they haven't habits and you should and say it's better or its worth this is this point and you should be aware of dozen differences in in culture in habits in order to do international business okay who they break or 15 nuts and other top i in the world is tourism here you can see how the tourism is increasing over the sir and for exam lin country like china many people have money no and in fact wino van shine a tent percent is well it is lyrical tent patient is medium and ethics patients track the to find can you like train to tent percent is well it is luigi you talk about 115 million people so they like to see their own country deeg tail tourism and from the teams did this in the past and here's is image disneyland in hong kong the where the wild disneyland there was no lente it was a b something like that was word there and the Dutch dredging company head to reclaim the lent and after that they beeld disneyland er another big thing is the Middle East Dubai Abu Dhabi 12 years ago they want to extend the coastline die koos the the total be light is not too much and is it wood and who does it well in view beeld put you can the structure this one day Calpam island wie course they make it in the shape of a part 3 this is also a couple we did want to extend it like this and then here you can see zondaar spot that suppose to be an artificial river in lente er with the ladder fries round it and it should be a tourist area this is the world the world is built by Feyenoord expression came or the couple my lens or something and the high beer was every country is an island you can buy the island of your country and images Philae discovered and Dando can detectives but unfortunately in 2000 case the financial price is the home market my thumb ni in westerns walked away and they didn't actually finishing closure came or the pantries is finished white slats building's a rose will not that the world is not finished and yeah well the problem is is you then do and not in if you don't take care of your protection am at erosion int and here's most of the island's will be to the listener and I deliver you want to finish the project where you have to start all over again but it will be love extra work moorings in the offshore and dredging moorings is a special topic picos all the floating pieces not the mooring system and a mooring system means fabian gables mean so santing under thief for that he seen as holding capacity especially the youforce is you cant see ankles like this week on week and with this something like a single pool into the soil and then it hasn't shirt and holding capacity a bit like ankles like this week as action anchors with would youtube cylinders with the pan want up you have to the cylinder under switch ubi soft sole am with the pump your points word there old creating and youtube under pressure and them because of that under pressure this had to into the ground and the certain holding capacity so that soul soweto only your as have gravity base tankers which is just use that knows yes such something very heavy you can pot undersea floor as soon as manyways in in want project to share with you it now that they the dual projects north of England' north of Scotland' the problem is so i floor is what and how to anchor doos tidal energy constructions in rok so that in fact what the student has to find out how to anchor santing has so i floor is what nick as normal anchors won't work maybe you have u thick train with such a special trencin machine pulley feel feel of of concrete and anchor in the concrete of santing that we don't know yet subsidies youtube picture but subsidy such as so deep-sea bridging of which will tell more and in fact this is clamshell toe thick matériaux we the clamshell is hydraulic and it has propellers for this dynamic positioning the cause you have your session clamshell the because 1000 to 2000 meters becomes adapt you can that check the clamshell is that ze problem in generally so who has dynamic positioning video cameras end and actually the operator can see around the mothership where the clamshell is and control joysticks by means of the dynamic positioning around the show Santinge built Pieter Schelte for those who don't know who have company in Delft takes as is' and as he is famous for in general by playing Wessels put options the the director at Waard Heerema who is the video or that company infections the owner of the company who puts in the notion we have crabs there are many bot and found it platforms in the North Sea not only in the North Sea neighborhood worldwide when they were built nobody' until about it that one day the heft your head picas forty years ago and they built dozen platforms people were not in general were not so concerned with the environment well everybody is busy with environment and according to the current standards yes I even platform is finished of their quickly morale in the feel you can adjust love platform the year after i move it with the platforms on that image for belt over the year built to stay there forever so here have put where you cam images ship and on one side which this site he knows buddha head on site of the platform and a this is the top site by the way so everything port side a week already the top site evolu kemp the top site to one site of the vesle and remake construction windows bars that week and lift the hollow feet to those had site then we have ship that can be moved box platforms well somewhat idle really like is the the ship something 300 for 10 meter hose and when the quinty meter swings and for the porter displacement is the toughest chip in the world so the company in the city he is the piglet strip in the world the price of the ship is about one point 5 trillion euros and by joel probably d financed summit knowing the paper but idea the lat just cash this is the policy of box small of company's so keep it sits work well here you can see the the the foot and this is the top site would have mechanism until I the dead silent bars think you scott this am white box that weisse stick a lift the high top site well in fact what d do something wetter lift what d do is my butter wood or the chips so the hole Schiphol go pap and that the WD lift the top site and the maximum know whether the tab site is twenty five thousand tons and to give you some impression a normal model car used how the model in Inholland and a medium k root beer builds because then lands a thousand kilos so twenty 5000 then you talk about twenty 5000 candle wax because that the lifting capacity around the site or so you was the platform as you can see here is discovered site of the ship the Schiphol move back to and then on the other site you see those still baars d connect the stiel baars with the foot like lord and the lord you lift youtube cylinders this knows pool box where so did you steal the pride discover and then they will fail to support and that's where everything will be this sample yeah they just got a greeting into pieces and probably at Tatasteel they will use administrative and so that's the way it work that you know and the stand is now so foot what this is not really big one but it could be handguards of meters high something like that who you youtube construction da building it now in korea and one of the problems of course you can not just leave bed foot lucas de bebat him on the foot jf concrete arrow chair the foot or to connect to the sea floor so this is a sort of the wise that you could use to kut the stiel baars and the concrete ende si floor so that like so yes and you type' of business equipment there was show we briefly all other equipment that he stood uw with chain process is peak oil between courseware who mainly focused on coating processes this is the picture of how i this here both 200 ears only 300 years ago 5 people on the wet mail measuring sating rotate that's why the bucket chain is rotating chains littlebits oled the bones and 5 people is indeed one person cuckoo the liver about 100 fifty becomes mainly d5 p plus 700 fifty words which is one horse power and so the power here is one horse power and that's open cent 5 kilo becomes maybe they produce want to keep ik not there per hour and if you could wear that we the current machines which shall also show you now they're talking about 25 to 13 make-up becomes in burst power just 15 people recently ship and you talk about productions this only up to may be 5x cubic minutes per second there so the dimensions completely spirit but first one day tail this car measurements it they they meet machines like this this is the roof the wheel in holland we used to have later hobby coal bin the lettered leftovers so white with the bins chain and in fact it's drawing of the top end and damping the matter you in in search' cart and railroad what you can imagine that such machine so ladder friction it's not very energy efficient with year in those days that was already the deer in the fifties most of those machines for still on there knows it our team engines and the course of the developments in the second world war with diesel engines in the fifties and sixties theory placed the steam engines with diesel engines we this is yes a machine the w-where name was young dough stiff I'll used Oathcarn the machine this is a model dredge cats great way you lie exactly such a dick point slater a lot you will see them this is a cats Gretsch the white on know is you got it.be whitefish you steal cylinder maybe two meters in that him it there white quite some weight they will draw pit in the soul and the cause of gravity I want to penetrate a couple of meters in the solid soul is not to heart and then the ship can rotate around that speedball and the from view app the leather this is the leather this one is 15 minutes flame and weiss about want a thousand currently and there the tab of the leather you have cutter it and he has such a house pictures oded leather the [ __ ] there it is chain the kind so it make circular movements putting the solo once it's finished how it one circle the letter will go down next circle and till you cover the height of the bank wrap this is what week already the bank in sai the [ __ ] there so and thor or whatever is mix white water transported to the pipeline and lord you see the pipeline leaving the ship going to heaven you guys the cent and that could be be this cubio where measurements gate sometimes you need is and if so where dredging to get cent put sometimes you just want to be move it if you will the gate in an area which was land it means you after i move the solo and dump it some place even lord you see the axis and edit up you have you electric motor driving the [ __ ] there it usually and dismay shop i ship the [ __ ] there it must have five megawatts of power to the axis what the f touch of that well if you catwalk and yes the problem weak is very hard anyway catwalk then the culture the food certain point will will will get stuck in the skirt that picos an electric motor hesse youtube maas moment of immersion the electric motor wants just continue turning the electric motor will not need is that the culture it is blocks you have nexus like this twenty 30 centimeters in that him it there the hole x is will lined up yes one of the ever something this week so that means the torque to the [ __ ] there it is increasing increasing and til it's big enough to to to make the wok collapse dancer the leader also will collapse the speed of the [ __ ] there the [ __ ] is normal sweet something like 5x meters per second to be double such a ladder up breaks out and then after third donation happens again the cat pieces do you know something like that arugula george and spring system and you can compare wit wit the the drilling the the vibrating drilling machine that use to drill in in your house and has use' hammered well yes do you have a new house made of concrete you win unita hammered will otherwise you can get into the wall mall is this vibration and and the shox the take care i get into the wall and in this case it storage and spring system that makes it possible to catwalk this is an ex number bio the man was the picture of course this is one of the belgium biggest [ __ ] addresses and this is the special lambie chose this is self propelled [ __ ] web's most of the [ __ ] adventure sarnath self-propelled they had just a rectangle there beard with the you leather and a [ __ ] there the and if you want to bring them to australia you have has the pokémon the heavy load chip do you have loading ship and bring them to the other site of the world this one can say bye it itself so that's on one side and it found its we this as we this website is now picos you create expert functional tea on board of the ship which makes it more expensive we this are ice ship and this one as lesson so vomit well compensation well lord you have [ __ ] there it and you can see the size micro very you via person and this is the typical rock culture the white big boys so all those tits did you see here who kolping boys and maybe you can see there still bar at the end of the pik point which is to depict point connecting the pik point with the rest of the culture it and once the pik point has toe with so again or maybe it's blocks you we the big hammer you can hit that steele there we move the pik point and put new big point around and the where cases where the again once soyuz lucas the rock is so hard that all the titan worn out in one hour and and about this specific project they spent half a million euros a week for your big point just for your big boys and then you can imagine if you can be used again and may be by changing the working with it or by proving the tied' yes you can 7 lot of money and so box company sa interest this in doing research to improve this may be for for those who don't know levies phd our [ __ ] up i in total must cost builds 500,000 euros waldes what they spent in a week so if you can improve that by tent patient unit and weeks to get the money back from the phd so yes this is word while doing research and that's what the dressing companies to this is another picture an artist impression of variation of sister [ __ ] there it you see all the ten mt this here and in fact this is the tail of the section line one of the problems and that's expressing that your phd is that if you care the rock the pieces of rock her so bic and when when they are actually got player download satisfied they have high kinetic energy bicos of of the refraction d shooter who would you get particles that can be quite big that go in and i directions so that's one pro and d d do n't follow the flow still you like all those pieces of rock to go into the pipeline and yes that horse or the production lovingly to the thief for a week all this stuff you after i moved and again and that's extra money so his phd is to in experiment in this process wrap this mixture formation in proving the mixture formation would you get higher efficiency of all those pieces of rock going into a system that one of the problems you will notice is this thing is rotating and you have have sanitizing that is rotating joralf centrifugal force and centrifugal for sizzle without words so the fact that this rotating and dead it wants to take the particles in the voting motion already creates is centrifugal force which ones to boswal the particles old so keep you deal we that one wit small particles dual they have the centrifugal force belly the particles her so narrow that the forces of the floor tom the particles to much higher so the floor will take them into the system and the spillage with very fine particles is my flash yeah so who who like to understand all the fish x in wolf tweezers process and that's why i fps the sand kind of [ __ ] up i and this one hills chicken we this out put this already on blackboard er of slideshow will you can look at all the pictures in this is a hopper dredge basically you hope getz is a ship sailing ship itself determines what the youtuber in the middle the hopper is to be felt wit be on play but usually we use it for cent jef toe dweck arm's and the details er like [ __ ] cleaners would you her moving sanitizing over the ground of kinds flow into the pipe and the hearer show signs my the particles we this will you have to details and toe in taste production who knows that the pan around the entrance of the pump the pleasure is limit that you can never hef more under pressure the entrance of the point and the injured the atmosphere i pressure that chose for angela the zero pressure you can get lower so deception treasure which is always under pressure is limited well eva increase the density of my mixture it is certain point the pump is emergency power in f so a depression is not strong enough to bol the mr insight so what you do over here your place the building SOS fit role in the section time then you can have higher density and so you go production with in Kees van Leeuwen will tell you more about that in the tail this is so a dredge with one section horse mean CD text and this the section tight and in this case you can use this ship for making trenches continuing guidelines for cables or would ever and in this way she could go to at least one 120 meters this is an exam on the bitterest heaps Gretsch Forties x 1000 cubic meters cover number is the size of the hopper that the lock or the half zip kids the sites or the heaps so the shipping Gary Dier became there Cly Forties x 1000 cubic meters of his and he must say you can fill the ship with cent in about to our so this roughly what you talk about Matt yeah something after is that you know a lot the Chippie was so cool when mtr and to empty it there three be this is one way Wijckel rainbow thing so the debate him or the hopper gravel Lotte hears a jets so it becomes jet's can make the cent flows am I know flow in a pipeline that they the bottom of the hopper this go seats point and the punks will pump it to this novel is yet and it could go up to like one handshake man 115 meters youtube realize that in the pipeline suppose the pipeline hesse that him the about bout one liter and the velocity insight the pipe is let's e56 meters per second and that's normal in dressing so in five weeks jed wit led c 20 centimeter opening that one gift of the that him the there so that's one-twenty gift of the cross-section this least redeemed is 20 5 times with high so the velocity over the words coming out of the jed would be like and the 20 5 meters per second something like that don't put your hen derbi course it will not last for one second and johannes came the the picos this is becomes there white cent I want euro in red everything that like reason that insight the pipeline henry calculate pipeline resistance picos who has a calculate powers wow count that the pipeline is must insight even is your tail white rust the pipeline and complete leo rusty after so and then the word rf wage then the pipeline for one minute something blinking to that insight to the site will take away all obstacles download any even or whatever in sochi pipeline it will not last for very long the cent will remove a greeting so you just want to have straight pipeline that's it the sec and 2 of emptying the shipp is bottom door so dr fell for door sin the bottom of the ship you can open them and laugh c in in 5 minutes because gravity all the cent is old and you dampen so that's in fact that the master who apply sec and 2 was the rainbow thing and the door two is that we so a pipeline sir you can connect floating pipeline that floating research you can connecting the coupling and then you can pump the site where ever you want so if you left to pass en tons beach you you that's what they use and they they use floating pipeline pompey to the beach buggy the becomes there is that piaf and so you can use rainbow went so yes budget sony has the word there is deep inside so she can get close to the show you can use rainbow ging to them pit camping by floating pipeline or by rainbow ging takes about so his time and filling the ship while but him through safari party there is there further system joest in the usa the that's for ships that are not to pick built for 5000 cubic meters amc picolit there split their barge would you have ship in the link there action something complete preferably this will you have access chips it the top of the ship so became deck your refuge berings in the front and in the back and in the bottoms you have viewed youtube cylinders and the grip is concert it in settsjo w that is the shipp is full and jewelers the pressure the ship wants open and all the matter you just want dropdown in less than one minute he wants us the ship and in the beginning it's scary picos yes you vote then a ship it is to have just connected by cylinder and one d empty the ship you actually feel that you move up jago sofa stucco and celebrate it and yes the first time you tank and wanted ship not think what yeah deo were use those tips for dirty here 200 g sing the reason they are not using that in europe is that box berings and cylinders for the review concerts the forces the year limited to certain scythe windows youtube chips like for the six thousand cubic meters if you what you is the berings around the dike and and cylinders in the bottom devout spicy your bite and it must that side too expensive yeah it's not competitive anymore promo audience technically they could make it it is the ship has the double price yeah it's not comes bad it is this is an exam hymn jets they use to start with jets yes oh this puts the and cool so action tripod overbuilding over the cent in the beginning you just have that weakness and the hal ajdir is loud pumpkins watered hears there wild flow and the this work the your get erosion of so end and the cent particles will flow white water into the system but you can imagine has you do the third a month or his tube get is a controllable in that pence to the erosion and speed put this if they deep and of the particles and if if if there would be some guilt in be to in the particles and the horses the the matériaux is a lion white can here itself yes us marshall les erosion ufr milo production it won't work so with the certain point deceptively put' titov stayed in the week it and who pull it over the ground where you can control how much earth titt be loaded work it lets eats and centimeter of anti centimeters and that way you can control your production week whether you the white or the pressure it you need the the fitness or the larry marketing dino the twins speaks about the chips would you know your production and you can calculate the density and son and just like that that's just eat well the problem is that is if you [ __ ] are thor play or the e of catwalk with box machines judge smoothly bitcoins in a catwalk the problem is that the the force to pull it to the material has to come from the propulsion of the ship have I as the chips cruiser whatever you use for that they have to push the ship and that way polderweg the steering wheel the solo well what is the efficiency officially propulsion how is my belt technology nobody' wall if you if you look at the efficiency over ship propulsion with beer sturdy percent maybe not much more that means but diesel engine has to the liver preferably 3 times the power that not for the fence process we dirty patient efficiency together white power if you are too busy anyway not man megawatt coating power after that not preferably remake what for me diesel yes then for the propulsion on the chips allah jealous lot of energy so understands ferry energy efficient one of the problems of the chain is that what we will see leder that you get under pressures in the shine youcat cavitation in the cent and that who will in very high chain frost so often could prevent those things to occur to the the a depression in the cent so becomes d d do here this is the heel the pot becomes the jets in the is it is week and floors guys the sent before box and the precious preference well how you just make the mercury cent am who don't have those you fence forces anymore and in fact the still use the tipi kas screed floors German and should be guided it into the week the west weeks ninety the greeter and to east including of 100 eat the grow that coin because around the ankles so reviews box that to guide the matter you into the system but we don't use them anymore for the wheel chain process many reviews becomes the jets toe floors guys so cent make it completely fluid and then if you look at energy you can an okay so somewhere underdeck opening what week already jed point centrifugal pumps that feeds the jets wit becomes there and then of the jed pump get the pipeline over your dweck arm all the way to grab it so handy energy that loes in sushi pipe evtimiy i the piper little bit bigger eylure slash where i an optima is this also a media still loes ten percent of the energy something like that that means of still has ninety percent of the energy available for those types of jets are you good have the issue in where use types of jets is the amount of energy in the cent so one for jets or for chain apricot I jets who quiet and times as much energy s chain are you quiet this same problem what of experts wino that has the jets the jets have the correct combining of pressure and flow micro power is pressure times flow will you can use a higher pressure and a narrow flori first it if you have the right settings are jets require built 17 percent of the energy of the chain process so icann safezone energy directly to the processes those gore jets your bottle energy Turk that percent lesson Buddha my my game is the mostly cash register oil of of the diesel engine eye on the news about ten percent in the process of getting the words of the wine white chain to the propositions to ai ai ai looks like seventy percent yes so jets and much more energy efficient and another advantage is that since i don't have the the pulling force anymore picasso not getting any more like and controls piet of the [ __ ] merge beds and so piet of the ship so not the band underlines of the sorry lanny barbie can would your ears that make it loose wit becomes there sits so that the bolts danny has backhaus and seaweed stre 5 minutes left so where we quickly go to it back as used to be more online especially this dozer callback actors a fairy youtube echoes and heave picture over backgro this one this is the back also the new york and this is the pick drawn and new york in fact this is me 12 years ago he heaven old picture of twenty years ago but i know that's we to was still smart and so on the niw you can see this is already your big big o the the beak actor's that your sons previous picture the year light and times he is big the her wheels use one of the problems is did you scale-up the design and one you just scale-up the design you you not seems that certain forse sarnath proportional to the length it maybe two the fall you become you the know over system and that's what happened windows use beakhouse lars dier we have student in westgate in that because they have ladder fractures and those bij cosy have ladder shox in in those things you get fatigue and certain tanks constant lee broke down v&d when to know why and what the main reason is that if you just scale up and reading linearly you forget that certain for they are naturally proportional this medical quaestor when the turk power so heavy the youtube berkhout clamshells what this is the clamshell show in the us youth to offer biggest of the is clamshell is for those five square meters and the traveling total cycle time of forty-five seconds that means of the barge we you this is the barge wehkamp the matériaux of the barge big the place where you wanted i trap that I do have go back damp in forty-five seconds but what kind of t5 cubic meters that means of cubic not the per second so thats clamshell can have production witjes could parable to medium-sized photograph zoos quite a lot to give you eh yeah this is picture show in hoop setup and this is the picture show in this for the five cubic meter clamshell it be thirty-six than in of me right something like that is big and it's ready and they have different configurations you have the very heavy one wit wit smaller cubic meters for heavy soy and the biggest one is for want tivoli soft short this there and is that clamshell live show you before it they hydraulic walls previous man is controlled by you closing why so they used tyres to close the clamshell company you are going to use it at 100 of meters of is being dept and they have closing lawyer and hoisting wire the holding will start spinning and box waijers want knew in that doesn't work anymore so if you go to ferry the porter what you do is your user hydraulic system that he does it x in the cylinders instead of wires to close the system and that's one of the things they are going to use in deep sea operation this is the trend how you also just header student who i had to make middle of the forces of boxes trendiez trends this is in fact right blue you can see you your pool in this direction and you just pool the cloud to the solo the cables well in here to this system and so so adhd add it to the bottom of d e trainers and this is for making of op popular putting gables under sea floor for offshore wind farms this ship is pulling the blue here did this test for the bid and the pulling force in this case the maximal pulling force under blue is for their turn now so this will so bad fate holiday in of your and dredging euroway store built along quantities unfortunately force is along powers and fitting is quite large yes this is the last of hills show you this is the cover donald of us is' and the cover donald is the trencher to does pipelines and the the solo so effect what do you do him view app pipeline that would fit in between heer den heer jungsheft' cover die weiss is they make ficheto trench en de the whole the wise is moving omtrek liken tank so the pipeline [ __ ] in the front roos under here you notice the ranch and die hain't the the four ickle it will job by gravity into the trains and then in fact the matter you yui moe futures does then the site and you hope that by current and be this material will blow back on top of the pipeline and cover the pipeline go after a while that will happen you would use the material that first your needs from the tram views use the same material to put back on tap of the pipeline okay that's it for two days tomorrow eiting tent early recognize a lot see you tomorrow
