Optimum Design and Control of Self-Supported Wave Energy Systems

In a previous paper by the authors [1] a procedure is given for the optimum design of single mass, anchored wave energy generators. The anchoring problem is generally regarded as one of the major obstacles of developing practical systems due to the high cost of implementation. This paper presents a procedure for the design of supporting platforms for wave generators which are essentially self-positioned and require minimum anchoring. The optimum design and control for such systems is given for a selected ocean condition. The study shows that an unanchored platform in an optimally designed two-mass system can provide appropriate support for the wave generator without any significant loss of conversion efficiency.
