STATISTICAL EVALUATION OF SHIP HULL DESIGN ICE LOADS

This paper summarises some of the results published in the author's dissertation. For a long term statistical approach, a semi- empirical approach is developed for estimation of long term ice loads on various parts of a ship navigating in the Baltic Sea. The empirical database required in the developed approach is gathered by four year measurements onboard MS KEMIRA. The effect of ship hull shape and ice breaking capability are included based on the calculated relationships applying an idealised statistical model of ship-ice impacts. An equivalent level ice thickness of a ridged ice field is determined to include the increase of load level caused by the consolidated ridged ice on various sea areas. The long term approach developed is verified by four year measurements onboard MS ARCTURUS.
