Abstract

A mooring line for keeping the position of a floating wave energy conversion is designed with using a commercial software, Orcaflex. Static analysis for one line is performed to decide the properties and pretension of a mooring line. With considering the ocean environmental condition and importance of a floating structure, the layout of multi-line is determined. The result of free decay of the designed mooring system estimates that the designed mooring system meets the resonance on the extreme ocean environmental condition. The initial design for mooring line is inevitably modified with adjustment of pretension. Adjustment of pretension with the change of length of mooring line results in the decrease of the ultimate tension on mooring line. The extreme value in tension of mooring line shows to be very sensitive to pretension of mooring line.th considering the ocean environmental condition and importance of a floating structure, the layout of multi-line is determined.
