Global strength analysis using 3D-FEM full extended ship models, in the case of equivalent quasi-static loads from oblique waves

Abstract

This study focuses on a new numerical method developed for the ships' strength analysis in the case of quasi-static equivalent loads induced by oblique waves, on full 3D-FEM models. The ship-oblique wave equilibrium parameters are obtained by own program P_QSW, using an 1D ship model. The equivalent wave pressure load is applied on the 3D-FEM model by own subroutines and functions. The numerical tests are done on a 97m length offshore barge.
