A floating marine platform is provided including a central column, at least three peripheral columns circumferentially around the central column, radially extending beams from the central column that connect the peripheral columns with the central column, and structural members spanning between each adjacent pair of peripheral columns. The structural members are pre-tensioned.

The disclosure provides a method and system to monitor and advise the status of a group of floating platforms, such as offshore floating wind platforms, by using a floating platform's motion in the group and detect one or more anomalies to identify one or more disorders (including irregularities) in the group. Input for this method can include information of wind speed and direction and orientations of the wind turbine nacelles. The orientation of the platform can complement the orientation of a wind turbine nacelle on the platform in case the platform is equipped with a turret. Disorders include, but not limited to, mooring line failure, shifts of a drag anchor, other issues with the mooring system components such as fairleads, issues with the ballasting configuration of the floater, issues with the turret (if any), issues with the swivel of the nacelle, issues with the rotor, and issues with the blades.

A system for converting fluid flow into electricity. The system has an arm assembly with four floats that rotate around a center float. The floats on the arm assembly are all provided with impellers that turn one half revolution for every one revolution of the arm assembly. This slow rotation maintains the impellers at the optimal angle to convert the flow of the water current into rotational motion of the arm assembly, regardless of the orientation of the arm assembly. The arm assembly is coupled to an electric generator provided on the center float that converts torque generated by the arm assembly into electric power that may either be stored on an on-board battery or transmitted by wire for use elsewhere.

A power generator includes a box-shaped body having an inner chamber containing a first gyroscopic device comprising that includes a first frame hinged to the body around a first axis, a first gyroscope being carried by the first frame in a rotatable manner around a second axis perpendicular to the first axis, a first actuator being carried by the first frame to rotate the first gyroscope around the second axis, and a first converter device that converts of rotational mechanical energy into electric energy that is mechanically coupled to said the first frame. The first converter device is connected to a stabilizing device. A second gyroscopic device includes a second frame hinged to the body around a third axis transversal to the first axis.

A power generation system anchored to a hydraulic arm, capable of pivoting up or down to optimize power generation based upon the present conditions of the flowing body of water. The turbines are augmented by diffusers to improve fluid flow and power generation. The overall design is easily built, installed, and maintained, providing easy power to homes without a need to connect to a public grid, and safety measures are affixed to prevent undesired items from entering the turbine propellers.

A floating platform for supporting generators of power derived from the wind, the waves and ocean currents, adopting an approximately disc-shaped general configuration with a circular or polygonal perimeter, which optimises its size and therefore minimises substantially its weight and likewise its production costs, as well as other associated complexities; which eliminates the possibility of entering into resonance with the movement of the ocean waves and thus not damaging the equipment installed, not overturning, and not surpassing the maximum list acceptable for wind power generators, nor wave power generators, nor ocean current generators; and which withstands the waves of the greatest size possible, all due to a ratio between its depth or height (13) and the diameter (14) thereof of between 0.06 and 0.35.

A marine plant assembly comprising a floating vessel and a plant operating unit attached to a buoyancy vessel in such a way that the operating unit is at least partially submerged during operation. At least one link element provides a hinged connection between the operating unit and the buoyancy vessel, thereby to allow movement of the operating unit from its submerged operating position to above the water level and adjacent the buoyancy vessel by said link element rotating into a position substantially parallel to the buoyancy vessel.

The present invention relates to a solution for a floating wind platform made of reinforced concrete for mass production, characterized by a geometric design providing a hydrostatic natural prestressing to the concrete, causing it to work under compression. The structural response of the platform for working in the most effective mode is improved, and the occurrence of fractures or cracks in the concrete is prevented, which reduces permeability and allows for reducing the rebar to be contained in the structure, also increasing operational safety. Furthermore, the invention has a system for anchoring the mooring lines to the structure in the form of a truss made of reinforced concrete which evenly distributes mooring stresses, minimizing prestressing in the high area of the platform, and increasing the area for distributing shear forces due to the change in section between the platform and the tower of the wind turbine. The geometric design furthermore confers the versatility of being able to adopt low draft SPAR, semi-submersible, barge, or buoy solutions, with the wind turbine being installed such that it is centered or off-center on the structure, thereby being adapted to different draft requirements or environmental and logistics conditions.

A hydrodynamic electrification system that generates electricity from water moving from a high side to a low side and around a structure that divides the low side from the high side generally includes a water transport system that directs the water from the high side presenting a hydraulic head, over the structure, and to the low side. The system includes a power extraction system having a wheel that receives the water from said water transport system and a mounting system having a high side anchor that connects near an intake to the water transport system at the high side and having a low side anchor that connects to the power extraction system at the low side.

The nacelle of a horizontal axis wind turbine is fixedly mounted on a tower, and the tower is mounted off-center with respect to a ring around which it is rotatable. The tower is a tripod. Two legs of the tripod are of fixed length and lie in a plane perpendicular to the axis of rotation of the turbine blades. The third leg of the tripod is of adjustable length and is aligned with the axis of rotation of the turbine blades. The third leg thus may be controlled to adjust for pitching of the base and other purposes. Multiple turbines, spaced apart laterally, may be mounted on a platform in a fixed orientation, with the platform rotatably mounted off-center relative to a base.
