Numerical analysis of an offshore platform with large partial porous cylindrical members due to wave forces

Min-Su Park, Kenji Kawano and Shuichi Nagata

Abstract

In the present study, an offshore platform having large partial porous cylindrical members, which are composed of permeable and impermeable cylinders, is suggested. In order to calculate the wave force on large partial porous cylindrical members, the fluid domain is divided into three regions: a single exterior region, N inner regions and N beneath regions, and the scattering wave in each fluid region is expressed by an Eigen-function expansion method. Applying Darcy

Key Words

large partial porous cylindrical members, eigen-function expansion method, wave excitation forces, substructure method, MCS method.
