Abstract

The distribution of ice-induced load on a ship hull is sophisticated. In this paper, Thick-honov regularization was selected as the inverse method to determine the load on the stern shoulder with full scale measurement data recorded on board PSRV S.A. Agulhas II during a voyage in Antarctica in 2013-2014. To simulate the nature ice features, three kinds of individual discretization were considered to describe the influence matrix of the model in FEM. Furthermore, the Thikhonov regularization equation was optimized with Matlab. The results demonstrate that the inverse method could be applied to overcome the ill-posed problem and solve the ice-induced load on a ship hull.
