Abstract

Transportation in ice prone waters is a timely topic due to the pursuit for natural resources and sea routes. The new Polar Code and aging vessels encourage modernizing the fleet going in Southern Sea. Polar supply and research vessel S.A. Agulhas II voyaged in Antarctic waters during austral summer 2013-2014. The ice-induced loads on ship bow were measured while the ship operated in ice. The operational conditions are described by ship speed, whereas the ice concentration was measured with visual observations while a stereo camera measured the solid surface ice layer thickness. The ice conditions varied from thin, first-year ice floes that the ship could push aside to thick, multiyear ice. The aim of this paper is to study how different ice and operational conditions affect the ice loads on ship bow. A model utilizing hierarchical Gaussian process was developed to study how the load distribution parameters change as a function of different ice and operational conditions. The results suggest that different conditions affect the ice load distributions.
