A marine wind power generation floating body according to an embodiment of the present disclosure can be coupled to a tower used for wind power generation and is provided at sea. The marine wind power generation floating body includes a floating main body which is formed at a predetermined length and which has a circular transverse cross section, a ballast part positioned on one side of the floating main body, a damping plate positioned at one end of the floating main body, and formed with a diameter that is larger than the outer diameter of one side of the floating main body, and a pitching/rolling damping part which is positioned on the other side of the floating main body, and which damps the horizontal pitching and rolling of the floating main body.

A buoyant hydrodynamic pump is disclosed that can float on a surface of a body of water over which waves tend to pass. The pump incorporates an open-bottomed tube with a constriction. The tube partially encloses a substantial volume of water with which the tube's constriction interacts, creating and/or amplifying oscillations therein in response to wave action. Wave-driven oscillations result in periodic upward ejections of portions of the water inside the tube that can be collected in a reservoir that is at least partially positioned above the mean water level of the body of water, or pressurized by compressed air or gas, or both. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power (making the device a wave engine), or else the device's pumping action can be used for other purposes such as water circulation, propulsion, or cloud seeding.

Power generated by a wind turbine is applied to drive reverse osmosis (RO) desalination. Rather than discharging the brine back into the ocean, it is concentrated and modified through industrial-scale processes to produce sodium hydroxide (NaOH). Direct air capture of CO.sub.2 occurs when liquid NaOH, created from the RO desalination brine, is conveyed to the rotor hub and emitted from the wind turbine blades to react with CO.sub.2 in the atmosphere. The power of an offshore wind turbine is used for the onboard production of fresh water to supply shoreside water needs, or water may be electrolyzed to produce hydrogen while adding the vital process of CO.sub.2 sequestration to the ocean.

The present invention relates to a floating support structure (1) provided with a main floater (2) and with a heave plate (3). Heave plate (3) comprises a section varying with depth. Furthermore, heave plate (3) has a minimum horizontal section Sd1 greater than horizontal section Sc of main floater (2).

The present invention is a floating support structure (1) provided with a main floater (2) and a heave plate (3). The heave plate (3) comprises a single row of orifices (4), substantially parallel to the periphery of the heave plate.

A method of installing an offshore wind turbine includes the step of raising a full-length tower for the offshore wind turbine by moving it longitudinally from a container in a substructure, the substructure being a support structure for the wind turbine, wherein the substructure is arranged with a container configured for housing a tower for the wind turbine substantially in its entirety.

The disclosure provides a wave sheltering vessel used to reduce the significant wave height of waves. The wave sheltering vessel includes a hull, a plurality of anchors, and a propeller system. A length of the hull is greater than or equal to 60 meters. A ratio of the length to a design draft of the hull is less than or equal to 6.5. A ratio of the length to a breadth of the hull is less than or equal to 3.5. A ratio of the breadth to the design draft of the hull is less than or equal to 2.3. The anchors are installed at the hull along a longitudinal direction of the hull. The propeller system is disposed at the hull.
