Estimation of correct ice load under various operating conditions is important during the design and the operation stages of anicebreaker. Normal operating conditions are expected from the official field ice trials and also from general ice transit action. In thispaper ice load for the Korean icebreaking research vessel, ARAON, under normal operating condition, is discussed. Published ice loaddata from full-scale sea trials of six icebreakers were analysed to derive an empirical ice load prediction formula. The IBRV ARAON hadsea ice trials during 2010 and 2012 summer season. Strain gauge signal were recorded during her icebreaking voyage and themeasured strain data were converted to the equivalent hull stress values. The effect of ARAON’s speed in ice and the hull stressesare investigated. By comparing the empirical formula and ice load calculation based von measured data, it is recommended to use theempirical ice load estimation formula for the initial design stage.
