Experimental investigation on the influence of interceptor plate on the motion performance of a cylindrical FPSO

In offshore locations with harsh environment, the operation of cylindrical floating production storage and offloading (FPSO) becomes more challenging. Poor motion performance can severely affect structural safety, mooring system's strength riser's operation. Therefore, interceptor plate installation above heaveplate is proposed in order to improve FPSO's especially heave responses. A set 1:100 scale model experiments were carried out University Strathclyde's Hydrodynamics Laboratory tank. The main objective this study investigate influence on a FPSO for different geometrical parameters such as height location. results show that double face reduce peak responses RAO by about 50% pitch 67% compared without plate. Also fundamental natural frequencies 11% same case.
