Heavy Polar Icebreaker Model Testing Underway
The U.S. and Canadian governments on Feb. 7 established a partnership that will enable the U.S. Coast Guard heavy polar icebreaker acquisition program to test and validate potential heavy polar icebreaker design models at Canada's National Research Council (NRC) in St. John's, Newfoundland.
In May 2017, the first test runs were conducted.
The Coast Guard will test multiple models with different hull designs and propulsion configurations this summer. The results of this model testing will further inform heavy polar icebreaker design and performance requirements. In addition to the modeling work that will be conducted at the NRC, the Coast Guard and Navy will conduct additional model test work to evaluate the performance of the icebreaker in open water at the Naval Surface Warfare Center, Carderock Division, in Bethesda, Maryland.
The NRC is home to one of the world's largest ice tank facilities, which is used to measure the performance and evaluate the safety of ice-going ships and structures in controlled model-scale conditions. The NRC ice tank is capable of modeling a wide range of marine ice conditions, including first-year and multiyear ice, pack ice, ridged ice and glacial ice.
