Mechanical Analysis for a Semi-Submersible Wave Elimination Device

This paper introduces a semi-submersible wave dissipation device used to dissipate waves and reduce vibration of floating equipment at sea. This semi-submersible wave elimination device is based on the basic principle of wave energy conservation in the local area, and induces resonance of the sea surface waves outside the beacon through the resonance module with special shape characteristics to redistribute the local sea surface wave energy near the offshore floating equipment, focusing the wave energy on the outside of the area, thus forming a stable area with low sea surface wave energy and small amplitude near the offshore floating equipment, thus effectively reducing the impact of sea surface waves on the offshore floating equipment. The impact of sea surface waves on the floating equipment can be effectively reduced. The mechanical analysis of some mechanisms is also carried out to verify the rationality of the device for the sea surface wave environment in actual use.
