AbstractIn 1991 the ODEN made a voyage to the North Pole. An area in the starboard bow of the ship was instrumented with strain gauges to measure local ice pressures. The ship encountered various ice conditions in its voyage, and whenever a threshold strain was exceeded, a 6 to 12 second-long “event” record of strains was made. Based on a finite element analysis of the ship structure the strains were converted to average ice pressures on a 40-sub-panel area, 10 frames wide (8.5 m) by 4 panels high (3.52 m). The bow is a “landing-craft-form”, sloped 22o from the horizontal. There were 784 events and for each of them average pressures on various area and shapes were determined and related to ship speed and ice conditions. A means of predicting probable ice pressures as a function of a “design” area and exposure is presented.
