SHIP ICEBREAKING DYNAMICS AND LEVEL ICE RESISTANCE TESTING ABOARD USCGC POLAR STAR IN ANTARCTICA

Tests to measure and record ship motions during icebreaking and maneuvering in thick level ice were conducted in McMurdo Sound, Antarctica aboard USCGC POLAR STAR from January 16-23. The objectives of the icebreaking dynamics phase of the performance testing were to determine distribution of magnitude and frequency of ship motions as a function of ice thickness and vessel speed; to analyze icebreaking patterns; and to measure ship level ice resistance and broken ice cusp size. The maneuvering test phase is reported in a separate volume published by Canadian participants.
