Commercial ships able to route through the Northwest Passage without ice breaker assistance are a step closer to becoming a reality. Korean shipbuilders, Hyundai Heavy Industries (HHI), announced a few days ago that a model of their 190,000 dwt iron ore bulk carrier had finished its test program in the world’s largest – 90 meters long – ice test tank at Canada’s Institute for Ocean Technology (IOT). With an awareness that the traditional ice-breaker bow construction (where the mass of the ship’s bow structure bears down to break up pack ice) acts as a drag on efficient progress in open waters, international collaboration between IOT and Korean researchers from Pusan National University aimed at finding the optimal bow design for a ship operating in various ice conditions. Numerical computer analysis by the team culminated in manoeuvring and resistance performance tests of the model bulk carrier in the special ice-test tank. Ship Model Testing in IOT Ice... [More]
