Abstract

In Taiwan, a floating Kuroshio turbine (FKT) system is under development by the joint research team of National Taiwan University and National Taiwan Ocean University. One of the issues which need be studied is its dynamics moored in deep sea. To understand the effects of mooring line materials on the system dynamics, we studied computationally the dynamic behaviors of the FKT moored with flexible ropes, chains, and 619 wire with wire core. In this study, we integrated several commercial and in-house packages. The system buoyancy and weight and their centres were estimated using the Rhino software. The system hydrodynamic coefficients were obtained through WAMIT, system drag coefficient through FLUENT, turbine propulsive force through lifting surface code, and system dynam-ics through OrcaFlex. We investigated the dynamic responses of the FKT system under waves with single frequency and random waves with different typical spectra.
