Abstract
A new physical model for very large floating structures (VLFSs) connected with an immersed module is investigated for a two-layer fluid, which may provide the basic knowledge to analyze multi-module floating structures in the stratified ocean. Under the hypothesis of small-amplitude wave theory, the case with the coupling effects by the wave motion, elastic deformation of the plate and the rigid body's oscillation is solved by considering a scattering problem and a radiation one. An inner product with orthogonality is used to calculate the undetermined coefficients in eigenfunction expansions. The exciting forces and the coefficients for added mass, damping, and stiffness are obtained.
