Multi-body point absorber system without a mooring

In this paper, we propose a multi-body point absorber system which can harvest ocean wave energy without needing a mooring. The proposed multi-body point absorber system consists of two elements: a multi-body point absorber that extracts the power from the wave, and a Wave Glider that keeps the whole system within a prescribed area. We describe the concept of proposed system. We analyze the heave dynamics of the multi-body point absorber and performed numerical simulations to validate its feasibility.
