    Abstract

    More and more floating structures are used in both offshore and coastal engineering, and also under assessment for wind energy. Mooring systems are needed by floating structures for station-keeping. In this paper, motion responses of a semi-submersible platform in regular waves are investigated numerically by a viscous flow solver naoe-FOAM-SJTU based on OpenFOAM. Influence of the mooring system on the motion responses of platform is evaluated via the study on (a) effect of each element length while maintaining the overall length as a constant; and (b) the cross angles between mooring lines.
