NUMERICAL SIMULATION OF 3D BREAKING WAVE MOTIONS ABOUT AN OFFSHORE STRUCTURE UNDER A SEVERE SEA CONDITION

Numerical simulation of the 3D breaking motion on a semisubmersible containing a circular cylinder mounted vertically onto a lower hull in regular periodic gravity waves was carried out. The TUMMAC-VIII finite-difference method is newly developed for such a problem. By use of the marker-density method the 3D breaking motion is approximately implemented in the framework of rectangular grid system. The generation of breaking waves by the interaction of incident waves with the structure is well simulated and interesting features of breaking waves are revealed with a certain degree of quantitative and qualitative accuracy.
