An Analysis of Hydrodynamic Interaction of Floating Multi-Body Using Higher-Order Boundary Element Method

Abstract

In this study, a higher-order boundary element method is used to analyze hydrodynamic interaction of floating multi-body system. Perturbation scheme is adopted to tackle nonlinear problem. Linear problem is solved using wave Green function. To investigate interaction phenomena, the radiation and diffraction problems for two rectangular barges are solved. The motion responses and wave drift forces are calculated, also. In the case of a platform-shuttle system, the hydrodynamic wave loads and motion responses are evaluated and compared for two different off-loading arrangement, tandem and side-by-side arrangement.
