Paper presented at the The Fifteenth ISOPE Pacific/Asia Offshore Mechanics Symposium, October 13–16, 2024
Paper Number: ISOPE-P-24-114
... ABSTRACT Floating offshore wind platforms with circular hulls are well-known worldwide. This study investigated the diffraction analysis of a 5MW NREL wind turbine supported by circular and elliptical hulls with aspect ratios of 1, 1.5, 2, and 2.5 using ANSYS-AQWA. Results showed a significant...

Paper Number: ISOPE-P-18-009
... ABSTRACT In modern computer aided ship design system, ship hull forms are mostly represented by the Non-Uniform Rational B-Spline surfaces and saved in IGES file format for data exchange between different CAD/CAM systems. Ship hull forms represented by NURBS surfaces have many good properties...

Therefore the similar way is regarded to be applicable for the estimation of the lateral drifting forces on the SWATH ship if the interaction between two hulls can be treated adequately. In the present paper a SSP model is considered and the results are shown fairly good...
