概要

Mooring simulation is very important to design mooring system of a very large floating structure of 5km in length. Hydrodynamic forces, wave exciting forces and wave drift forces are necessary for this simulation, however, source distribution method, commonly used to calculate hydrodynamic forces for conventional floating structure, requires huge number of source panels on the surface of a floating structure and is time consuming for the computation. In this paper, computed results of hydrodynamic forces, wave exciting forces and wave drifting forces acting on a very large floating structure are shown. These forces are computed by three-dimensional velocity potential continuation method, because this method need much less memory and CPU time compared with the source distribution method. Results of mooring simulation of a very large floating structure using the hydrodynamic forces obtained are also shown here, and characteristics of mooring simulation results are studied.
