Application of a Nonlinear Time Domain Hybrid Method to the Study of a Semi-Submersible in Waves

摘要

The focus of this paper is on the application of a time domain hybridrnmethod to the calculation of the motions and wave loads on a semisubmersible,rnwhich has been investigated extensively in ITTCrnbenchmark studies in the past. Numerical results include hydrodynamicrncoefficients, motion responses and drift forces. Good agreement hasrnbeen observed between the results of the present method, otherrnnumerical codes and experimental data, which confirm the capability ofrnthe developed numerical approach to deliver meaningful predictions forrnpractical applications to offshore structures.
