Abstract: The present invention relates to a floating mounting (1) which includes ballasting means (2) in order to vary the draught of the floating mounting. The floating mounting (1) according to the invention has a depth-variable horizontal cross-section, such that the second moment of area of the cross-section of the floating mounting, at the buoyancy surface (Sd), is higher when the floating mounting is deballasted, compared with the second moment of area of the buoyancy surface of the floating mounting, at the buoyancy surface (Sb), when the floating mounting is ballasted.

Abstract: The present invention relates to a motion compensation system for an element hanging from a mobile unit, the system comprising two blocks, at least two articulated arms, a compensation cylinder and a cable. According to the invention, at least one characteristic length of the articulated system (for example: the length of a link or the distance between two sheaves of two articulated arms) is adjusted according to the motion to be compensated for.

Abstract: The present invention relates to an offshore wind turbine on a floating support (1) comprising either a rotor with a horizontal rotation axis (horizontal-axis wind turbine HAWT) or a rotor with a vertical rotation axis (vertical-axis wind turbine VAWT) with the rotor being mounted on a floating support having a principal axis. According to the invention, the principal axis of the floating support is offset by an angle α with respect to either the axis of a tower carrying the horizontal-axis rotor or to the rotation axis of the vertical-axis rotor.

Abstract: The invention is an ocean thermal energy conversion method and a system in which a motive fluid having predetermined characteristics is circulated in a closed loop between a cold source in cold deep ocean water and heat sources in warm surface water. The motive fluid is compressed between the cold source and a first primary warm water heat source resulting in the motive fluid being substantially totally vaporized at an outlet of the warm water heat source. The motive fluid is heated downstream from the primary heat source by a secondary heat source. The thermal energy of the heated motive fluid is recovered from a turbine and the motive fluid is condensed in the cold source.
