Full-scale Measurement of Japanese icebreaker Shirase in Antarctic Sea Ice – Relationship between Ship Structural Response and Ice Conditions

Junji Sawamura, Associate Professor, Department of Naval Architecture and Ocean Engineering, Osaka University, Osaka, Japan Cambridge Fluids Network - fluids-related seminars 8 November 2024 2:30pm British Antarctic Survey, Seminar Room 2 Japanese Antarctic Research Expedition (JARE) began in 1956. Japanese Antarctic research icebreaker Shirase has engaged in the transporting cargoes and scientists in order to operate and maintain the Japanese Antarctic research station Syowa since 2009. In order to ensure its safe voyage in Antarctic Ocean, the motions of the icebreaker Shirase and the ice conditions are monitored. This research presents monitoring data of the icebreaker Shirase during its voyage in the 55th Japanese Antarctic Research Expedition (JARE 55) from December 2013 to February 2014. The icebreaker Shirase encountered in various ice conditions such as pack ice, level ice, and multi-year ice in JARE55. The ship structural response of the shoulder hull and the bow deck in those sea ice conditions was investigated. The relationship between the structural response and the ice conditions of Shirase in Antarctic Sea ice are discussed.
