Floating structure for wave protection and wave-energy conversion

摘要

Floating structure for use in the offshore area with a combined application as wave protection for floating wind-energy converters positioned on the lee side and for utilising the wave energy for power generation. The structure is composed of a plurality of modules according to the size of the wind-energy converter units to be protected and is anchored on the windward side of the wind-energy converters. For the utilisation of the wave energy, the principle of a narrowing wave channel is used in which the kinetic energy of the deep-water wave is converted into potential energy. This action is intensified by a rising channel base as well as by reflection effects at the end of the closed channel. The floating wave-energy converter can be set to the respective prevailing wave conditions by flooding and pumping out, as a result of which effective utilisation of the annual supply of wave energy at its respective position is achieved. The structure is set up at suitable places at the coast and is subsequently also maintained/overhauled there in order to then be towed in a floating manner to its place of use in the coastal offshore area and anchored there.
