Complete wave power absorption is studied by using a two-dimensional floating body of symmetrical section, which oscillates in three degrees of freedom, and two kinds of energy absorbing mechanisms. One of the mechanisms is a single energy absorbing mechanism which exerts the reaction force on the floating body at a point away from the center line of the floating body. The other is a pair of single absorbing mechanisms which exert reaction forces on the floating body at the points symmetrical about the center line of the floating body. These power absorbing mechanisms are activated by the heaving motion at the points where the mechanisms are articulated with the floating body. The conditions, which the characteristics of the power absorbing mechanism and the floating body should satisfy for complete wave power absorption, are derived theoreti-ca11y for both configurations of the power absorbing mechanisms. Furthermore, a model test on wave power absorption in regular waves is carried out for the pair of single energy absorbing mechanism and the results of the test show that complete wave power absorption is possible by using a two-dimensional floating body of symmetrical section which oscillates in three degrees of freedom.
