STUDY OF WAVE IMPACT ONTO A SEMI-SUBMERSIBLE PLATFORM USING MOVING PARTICLES SEMI-IMPLICIT (MPS) METHOD

Bellezi, C. A.; Cheng, L. Y.;

Full Article:

This paper presents a study on the complex phenomenon of fluid-structure interac-tion involving the wave impact onto semi-submersible platform by using Moving Particles Semi-Implicit (MPS) method. The MPS method is a fully lagrangian particle-based which is originally developed to model incompressible flows and is promising in highly non-linear phenomena analysis, such as the hydrodynamic impact with large free surface deformation and fragmentation. Is this study hydrodynamics of wave in deck impact and wave runup in two different type of semi-submersible platforms, with square section columns and with circu-lar section column are considered. Also, the effects of the motion of the platforms of the phe-nomena are analyzed by comparing the responses when the platform is fixed and is free float-ing with coupled heavy and pitching motions.
