Semi-submersible structure for wave energy harvesting (courtesy of Hidroflot)

Semi-submersibles structure for wave energy harvesting of 6.5MW nominal power.
Main characteristics: B=44.62 m, D=23.28 m y T=16.32 m.
It is composed of a steel frame consisting of 16 vertically connected pipes floats in the sea. A movable buoy is fastened to each of these pipes. When a wave runs through the steel structure, each buoy moves at its vertical pylons. This up-and-down movement is transformed into a rotation with which a gear then drives a generator. A cable on the seabed brings the electricity generated in this way to the land.

The movie shows the results of the detailed structural analysis of the gear and generator supporting structure.

Analysis carried out with Tdyn-Ramseries (http://www.compassis.com).
