ANALYSIS OF ICE LOAD ON THE IBRV ARAON DURING ICEBREAKING PERFOMANCE TESTS IN THE ARTIC AND ANTARTIC Sea ice processes
Author : Kyungsik Choi, Eun-Jee Cheon, Tak-Kee Lee and Hyun-Soo Kim
An icebreaker under field ice trials suffers significant ice load on ship‹s hull. Estimation of correct ice load under various operating conditions is important during the construction and the operation stages of an icebreaker. Normal operating conditions are expected from the official field ice trials and also from general ice transit action. In this paper ice load for the Korean icebreaking research vessel, ARAON, under normal operating conditions is discussed. Published ice load data from full-scale sea trials of various icebreakers were analyzed to derive an empirical ice load prediction formula. The IBRV ARAON had Sea ice processes trials in the Artic and Antarctic Sea ice processes during 2010 and 2012 summer seasons. Strain gauge signal were recorded during her icebreaking perfomance test and the measured strain data were converted to the equivalent hull stress values. In this paper the effect of ARAON‹s speed in ice and the hull stresses are investigated. By comparing the empirical formula and ice load calculation based on measured data, it is recommended to use the empirical ice load estimation formula for the initial design stage.
