They want conditions in a test pool to resemble the Arctic environment. \u003cbr\u003e\u003cbr\u003e Salty water here is at freezing point. Scientists first measure the thickness of the forming ice sheet. \u003cbr\u003e\u003cbr\u003e “In every test we perform some 200 measurements. We measure the thickness of the ice sheet in 200 different parts of the pool,” explains ship design engineer Quentin Hisette.\u003cbr\u003e\u003cbr\u003e “This is because the ice is not uniformly compacted everywhere. It is the same situation we find in the Arctic. So we need to try to obtain a good average (for ice thickness) with tests that are sufficiently long, meaning that the data and measurements we get are accurate enough”. \u003cbr\u003e\u003cbr\u003e With the test tank ready, naval and mechanical engineers take over. They use this model to assess how a newly-designed, larger ship propeller would perform in extreme conditions. \u003cbr\u003e\u003cbr\u003e Rene Bosman a mechanical measurement engineer at the Maritime Research Institute in the Netherlands outlined how the tests are performed. He told Euronews:\u003cbr\u003e\u003cbr\u003e “At the front we measure the resistance of the model. Here at the back, we measure the rotating speed of the propeller, as well as its thrust and torque. And we also measure the side forces, and the bending moments”. \u003cbr\u003e\u003cbr\u003e The experiment is part of a European research project aimed at developing more efficient vessels which cause less pollution. Researchers say that this particular model propeller is very promising.\u003cbr\u003e\u003cbr\u003e .csikow FoEE_Antoine e.g. #H2020 Greener ships to save #energy \u0026 ↘︎ #CO2 See also #LeanShips #\u003ca \u003ca href='https://t.co/cClllkPo6j' target='_blank' rel='nofollow'\u003ehref=\"\u003c/a\u003e\" rel=\"nofollow\"\u003eEUTransportResearch\u003c/a\u003e— Andreea STRACHINESCU (@stracma) March 14, 2017\u003cbr\u003e \u003cbr\u003e\u003cbr\u003e “We have learned that this is indeed a very nice concept (for a propeller).

So tug-boats have to have more power, but they have less space in which to manoeuvre,” explained mechanical engineer Robert Van Koperen. \u003cbr\u003e“So this new hull shape will enable us to be very manoeuvrable”\u003cbr\u003e\u003cbr\u003e The next step is to build tugs that run on compressed natural gas.
