The Wave Loads and Outrigger Hulls’ Position Optimization for Trimaran Traveling in Waves

Abstract

Abstract: Because of the interaction between the main hull and the outrigger hulls the wave loads will be quite different by different arrangement. Based on the threedimensional potential theory and Green’s function, the wave loads, including vertical shear force end vertical bending moment at different locations on the main hull with respect to different staggers and clearances, were derived by the spectral analysis. Several ship speeds and wave headings were also considered. A suitable arrangement was got by comparison.

Key words: trimaran, three-dimensional potential theory, optimum of outrigger hull, wave loads
