A wave energy converter includes a buoyant body and an acceleration tube with a working cylinder and working piston movable therein, a mooring system, and at least one energy collecting device including a hydraulic pump in the form of a hydraulic cylinder having a jacket and an internal pump piston connected to at least one piston rod, which forms a mechanical connection between the buoyant body and the working piston in the working cylinder, wherein at least one float body having a buoyancy in the body of water where the wave energy converter operates is connected to the working piston and wherein the buoyancy of the float body is adapted to maintain the working piston in a desired vertical operating range in the working cylinder when the wave energy converter.

A support system for offshore solar photovoltaics equipment includes a float platform, a plurality of float bodies, at least one ballast member, and at least one carrier frame. The float platform extends in a longitudinal direction, and defines a plurality of limiting grooves each of which extends in the longitudinal direction. The limiting grooves are spaced apart from each other in a transverse direction transverse to the longitudinal direction. The float bodies are disposed in the limiting grooves and protrude out of a bottom surface of the float platform. Each of the float bodies surrounds and defines an inner space adapted for a liquid or a gas to be filled therein. The ballast member is connected to the float platform and extends downwardly from the float platform across bottom sides of the float bodies. The carrier frame is disposed on the float platform and defines an accommodating space.

Proposed is an arrangement of local structures for TLP-type floating offshore wind turbine platform stress distribution and strength enhancement, the arrangement being characterized in that a plurality of supporting members of which at least one is elongated in a different direction protrudes from the bottom plate of a node, so the top plate of the node to which load is applied by a wind turbine is supported by the supporting members, stress is distributed, and damage to the top plate is prevented such that the wind turbine can be stably supported through the node.

An offshore system for growing and harvesting seaweed. In some instances, the offshore system for growing and harvesting seaweed includes an existing non-producing offshore platform. In addition, in some instances, the offshore system for growing and harvesting seaweed includes a seaweed support system coupled to the platform and configured to support the subsea growth of seaweed.

A tower-integrated offshore wind power floating body includes a tower formed under a power generation unit, transition pieces (TPs) spaced apart from a lower circumference of the tower at regular intervals, a seating part formed under the tower and the TP to support lower portions of the tower and the TP, a reinforcement column having the same axis as a vertical central axis of the tower and formed under the seating part, a buoyancy part formed under the reinforcement column, a ballast part formed under the buoyancy part such that the ballast part is spaced a length from the buoyancy part, a brace formed between the seating part and the buoyancy part, a brace formed between the buoyancy part and the ballast part, and main columns arranged in a vertical direction in the TP, the seating part, the buoyancy part, and the ballast part, and the main columns.
