Full Scale Measurements of Ship Ice Loads and Performance on Board R/V Akademik Fedorov on Her Voyages in Antarctica and Arctica

摘要

The full scale measurements of ship ice loads and performance in polar ice conditions are presented. The measurements were conducted on board an icebreaking research vessel Akademik Fedorov during her voyages in the Weddell Sea, Antarctica 1991-92 and on the Northern Sea Route, Arctica 1994. The instrumentation and calibrations of the measuring system are presented. Ship's route and ice conditions on the voyages are described. The measured ice loads, ice pressures, hull stresses and ship performance are analysed for different sea areas. The extreme values and statistical predictions are given. The results in Antarctica and Arctica are compared with each other.
