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.

A floating dockable liquefied natural gas supply station, comprising: a main hull, a bottom base and a positioning system. The bottom base comprises a base plate or at least two base plates. The base plate is securely connected to a lower lateral side of the main hull by means of a splicing securing system. Therefore, the main hull and the bottom base of the floating dockable liquefied natural gas supply station can be assembled in a modular manner. It is possible to individually construct the main hull and bottom base of the floating dockable liquefied natural gas supply station, and to then use a modular method for connecting and assembling same on the ocean or on land, thus being able to flexibly form various types and dimensions of supply station, allowing for docking transport vessels accommodating various loading capacities of liquefied natural gas (LNG), and reducing the construction cost thereof.

A semi-submersible floating offshore vessel has a deckbox structure with a main deckbox bottom extending underneath a lower deck. The deckbox structure includes a recessed cellar deck structure that protrudes below the main deckbox bottom, which recessed cellar deck structure has a cellar deck bottom wall that is closed and wave impact resistant and which recessed cellar deck structure has a peripheral wall that is closed and wave impact resistant. The peripheral wall extends between an outer perimeter of the cellar deck bottom wall and the main deckbox bottom of the deckbox structure. The moonpool extends through the recessed cellar deck structure. Seen in plan view, the recessed cellar deck structure includes a number of pointed wave crest splitting sections.

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.
