This invention relates to a combined offshore system for generating electricity, comprising of an offshore windmill unit with a generator for extracting power from wind and transferring it into electricity, a electricity export cable connected to the windmill for exporting produced electricity to offshore or onshore consumers, and at least one offshore wave power unit for extracting power from waves. This offshore wave power unit is characterized in that electricity produced by the wave power unit is transferred via the same electricity export cable as the electricity generated by the windmill unit, wherein the windmill unit is a floating unit.

The invention relates to a cryogenic fluid offloading system, having a tanker vessel for loading liquefied gas at a first location, transporting it and offloading the liquefied gas at a second location, the tanker vessel being connected to the mooring structure via the connecting member. The regasification plant has no large storage facilities, the tanker being unloaded in dependence on onshore demand for gas.

The invention relates to a floating offshore structure (1) anchored to the sea bed (30). The floating offshore structure (1) comprises a hull (2) having longitudinal sides (3,4) and transverse sides (5,6), bow and stern anchoring points (13,14,40) for mooring a tanker vessel (7) alongside the offshore structure (1), a main deck (25) at a predetermined height (H1) above sea level, hydrocarbon storage and/or processing devices (26) being placed on the deck (25), a spacer member (20,21) attached to the structure (1) and projecting transversely from the sides for contacting a tanker vessel (7) moored alongside the structure (1). The anchoring points (13,14,40) of the structure comprise of quick release members (60), wherein the bow and/or stern anchoring points (13,14,40) of the structure (1) are situated on a secondary deck (28,39,51) which projects transversely from the hull (2) of the structure (1) substantially at the heights (H2) of anchoring points (34,35,36) of the tanker vessel (7).

摘要:
An off-shore structure is installed in a body of water. The body of water extends above a floor, such as a seabed, and has a water surface. A buoyant pontoon and a top structure are provided separately from each other. The top structure has a deck, a plurality of legs that are connected to the deck, and a jacking system for displacing the legs relative to the deck. The pontoon is submerged below the water surface. The submerged pontoon is connected to the floor with tendons. The top structure is aligned above the submerged pontoon connected to the floor. Then, the legs are jacked-down relative to the deck until the legs abut against the submerged pontoon connected to the floor. Subsequently, the jacked-down legs are attached to the submerged pontoon and the deck is jacked-up relative to the pontoon until the deck is standing above the water surface. A number of risers are installed for providing a fluid communication between the floor and the deck after jacking up the deck above the water surface.
