Numerical investigations on transient behaviours of two 3-D freely floating structures by using a fully nonlinear method

Abstract: This is the accepted version of the paper.This version of the publication may differ from the final published version. Abstract: Two floating structures in close proximity are very commonly seen in offshore engineering. They are often subjected to steep waves and, therefore, the transient effects on their hydrodynamic features are of great concern. This paper uses the quasi arbitrary Lagrangian-Eulerian finite element method (QALE-FEM), based on the fully nonlinear potential theory (FNPT), to numerically inves… Show more

“…A body is then placed in the tank and the whole simulation starts when the wave maker starts motion. The finite element method (FEM) method has been extensively used in a wide range of problems, including fixed cylinders [1], vertical cylinders and a simplified floating production, storage and offloading (FPSO) vessel only in surge motion [2], a non-wall-sided structure which is fixed or in forced surge or heave motion [3], an array of fixed cylinders [4], a SPAR platform, a barge-type floating body and one or two Wigley Hulls with motions of six degrees of freedom in head seas or in oblique waves [5], two 3D floating structures in close proximity with motions of six degrees of freedom [6]. The BEM method has also been widely used.…”
