Abstract
As the increasing demand for energy and the growing awareness of environmental sustainability, researchers are dedicated to developing innovative energy devices. Kuroshio Current is one of the potential marine energy that can be widely extended and applied in the future. However, the hydrographic features around Taiwan are unpredictable and the related geological surveys are also not well clear now. Hence, the investigation of how to set the ocean turbines on the operating location safely is the important key to promote technology development. To resolve the issue, it’s necessary to establish an appropriate simulation environment by the software to evaluate the operation procedures and the actual situation that may be encountered. This thesis is based on the motivation mentioned above. We use the OrcaFlex, a fairly mature software program on the field of marine oil and gas development, to do the numerical analysis about the Floating Kuroshio Turbine (FKT) under the rated flow 1.5m/s. By controlling the different income rate of seawater by buoyancy engines can make FKT to the target depth of location in order to work normally and reduce the impact of heavy swell. Last, we analyzed and designed available mooring and anchoring system according to the simulation results. Moreover, we use the Computational Fluid Dynamics (CFD) software ANSYS-FLUENT to calculate the hydrodynamic coefficients of the anchor system to complete the series of design.
