Study on Resistance Performance of Icebreaking Cargo Vessel in Pack Ice Condition according to Variation of Synthetic Ice Thickness and Hull Form Characteristics

open access: yesJournal of the Society of Naval Architects of Korea, 2009
AbstractThe present paper deals with characteristics of resistance perf ormance according to the variation of synthetic ice thickness and hull form. The resistance test has been conducted with pack ice condition in Pusan National University towing tank. Stem angle has been chosen as main parameters for the variation of hull form charac teristics, which
