Wave Energy Absorption by a Moored Floating Body

Abstract

It is necessary that the floating type wave absorber is supported by mooring lines. However, since the floating body has three degree of freedom when it is supported by mooring lines, the efficiency of it which is designed for heave or roll motion only, may be expected to decrease. Therefore it must be designed under the condition of three degree of freedom. This report shows a procedure of optimum design of the floating body supported by mooring lines. Furthermore, model tests on wave power absorption are carried out and the results of the test show that the complete wave power absorption is possible by using the present method.
