Systematic Design of a Heaving Buoy Wave Energy Device

Oscillating type devices constitute a major class of offshore wave energy converters. In view of the characteristic of the wave energy in China that is low in energy density, a new heaving buoy wave energy device is designed. The paper introduces the basic components of the device, including buoys, support platform, submerged platform, anchor system and hydraulic power take-off, addresses the system design of the device and explains the working process of the converter. The physical experiment is performed in Shandong Provincial Key Laboratory of Ocean Engineering, China. The result shows that the heaving buoy wave energy device is simple, the energy acquisition system is stable and the efficiency is high.
