unidentified female [robertson]: “this projectis devoted to offshore floating wind, and in that regard, the whole world is in itsinfancy right now.†unidentified male [goupee]: “there are alot of technical problems to solve, but the energy potential is huge here, and if youget it right, you can really make a big difference.†unidentified male [kimball]: “the scaleof this energy is of the scale of our national
Offshore Job Holland, energy needs. it's very large.†narrator: “in the spring of 2011, the effortby the university of maine's advanced structures & composites center to develop offshore floatingwind turbines took a big step forward. scaled-down versions of three design concepts were putto the test in these state-of-the-art basins
at marin, the maritime research instituteof the netherlands, located in wageningen, holland. to this point, umaine scientistsand engineers have been working with numerical models. but computer simulations can't capturewhat happens when wind and waves are hitting an actual structure. these tests will improvethose models and make the data publicly available.†andrew goupee, assistant research professor:“we've been doing some testing in them and seeing some things we hadn't imagined we wouldexperience or seeing new phenomena, and we kind of need that information so that we cantry to get our models to capture that.†rich kimball, professor of engineering, mainemaritime academy: “and that's very useful for us in improving the models and pushingthe limits, because we really want to be able
to predict failure. the alternative is youlearn that for the real-world case, and that can be disastrous.†amy robertson, senior engineer, national renewableenergy lab: “this is a very important program, and i've heard people from all over the worldbeing very excited about this program and the fact that it's going to be made publiclyavailable to everyone. i mean, that's just going to give so much information to the world.†narrator: “this miniaturized boat beingtossed around in the test basin is a scale model of a 150-foot vessel, and it's beingsubjected to a scaled-down major hurricane. while the boat is having a rough time, the1/50th scale model floating turbine is weathering
the storm well. off the coast of norway, thenorth sea dishes out the real thing. but this first-in-the-world, full-scale floating turbine,developed by statoil, an oil and gas company, also seems to be withstanding the storm. developinga floating platform that can stabilize a 300-foot-tall wind turbine and produce energy cost-effectivelyrequires an engineering balancing act.†goupee: “because these will ultimately bedriven by cost – you know, an investor wants to put in as little money as he can and maximizehis return – we can't build big, bulky offshore oil- and gas-type structures. if they're toobig, they're too expensive, you never get your money back.†bas buchner, marin president: “you wantto have something which is stable in wave
conditions, for instance, with wind conditions.what you're doing now is putting something on top of that structure which is moving,which is flexible, and technically that is extremely challenging.†goupee: “you have this huge tower with thispoint force on the top, and it's trying to tip the structure over, and you have to opposethat somehow, so you can only, you know, skimp so much on the foundations, and it's a uniquebalance.†narrator: “the data from these tests willbe key to the next big step in developing maine's offshore wind resource, which willput a scale model prototype floating turbine into the waters of the gulf of maine off thecoast of monhegan island.â€
anthony viselli, research engineer: “ourlaboratory is the gulf of maine, so you see this wave basin here. we can apply whateverwind and wave conditions we want. well, we're basically taking the same idea, but let'suse the ocean now. we can go much bigger, and we can learn a lot more at that scale.the challenge, though, is that you don't have control over it.†narrator: “the ultimate goal of umaine'sresearch efforts in offshore wind is to develop 5 gigawatts of electricity off the maine coast.that is roughly equal to 5 million nuclear power plants' worth of energy – enough powerto play a significant role in the national energy picture while it creates jobs in development,manufacturing and maintenance.â€
robertson: “the government, as it sees itright now, our goal is to try to get 54 gigawatts of offshore wind power by 2030, and they seethat as a really strong component of how we're going to meet our renewable-energy needs.†buchner: “the major challenge is makingit so efficient and so reliable that, in the end, we can do it for a low-cost price, andthen i think there are huge opportunities.†goupee: “my family all grew up in maine,i'm from maine, my wife's family's from maine, and i don't want to leave, and it's very importantto me that, as we can do something that'll hopefully provide jobs here. there isn't muchbig industry, and i think, i won't say that this is going to be the solution, but we needto start pursuing some solutions that will
improve the economy in maine and make thingsmore affordable for mainers, make it easier for people to stay here.†kimball: “this is one of the most rewardingprojects i've ever worked on. i mean, to be involved in sustainable energy for our country,for the world, you know, weaning ourselves off fossil fuels, you know, it's somethingnecessary, and for an engineer, this is why you become an engineer.â€
