A floating VAWT comprising a wind turbine body having a lower body portion and an upper body portion; at least one blade attached to the upper body portion for converting wind energy to rotation of the wind turbine body; and an energy converter attached to the wind turbine body for converting the rotation of the wind turbine body to electrical energy. The energy converter comprises a first energy converter part, and a second energy converter part to be kept relatively stationary in relation to the first energy converter part. The energy converter is attached to the wind turbine body by means of a first releasable mechanical coupling between the first energy converter part and the lower body portion of the wind turbine body, and a second releasable mechanical coupling between the first energy converter part and the upper body portion of the wind turbine body.

A process for repairing a surface includes the mixing an epoxy resin formulation part A with a part B. The part A includes phenolic epoxy resin, polyol epoxy resin, or lipid epoxy resin, or a combination thereof. The part B includes a curing agent of only an aliphatic amine, a phenalkamine, a phenalkamide, or a combination thereof, to form a mixture. The mixture is applied to a substrate of the surface in need of repair to a thickness of up to 6.35 mm. The mixture cures on the substrate under conditions adapted to a dry to sand condition in 120 to 200 minutes. A process of operating a repaired marine substrate in a water contacting environment with limited water absorption is also provided. A composition for use in these processes is also provided.

The present invention relates to an apparatus for providing access to equipment or structures that require maintenance. More particularly, the present invention is suitable to provide access to equipment or structures located offshore, such as wind turbines or structures for oil and gas production. The apparatus comprises a deck, an apparatus structure for supporting the deck, a platform and a platform support mechanism. The platform is movable with respect to the deck from a stowed position to an extended position. In the extended position the platform forms an extension to the deck. The platform support mechanism comprises at least one cable and at least one compression post. The/each cable has a cable first end attached to the platform at or adjacent to a platform leading edge and a cable second end attached to the platform at or adjacent to a platform trailing edge. The/each compression post supports the cable between the cable first end and the cable second end and is adapted to maintain a substantially constant tension in one of said cables as the platform moves from the stowed position to the extended position.

A system and process is provided to deplete or remove moisture from wood coring in boats by piercing 20 a fiberglass outer skin; forming 30 bores or holes 200 in wood coring to form an exposed portion; processing ambient air 35 to create processed air; pumping or displacing 40 processed air into the bores or holes 200; penetrating 50 an exposed portion 80; with a sealant 100; and filling 60 the exposed portion 80 with a sealant 100.

The present invention concerns a bulbous bow for a sea-going vessel, said bow comprising a load-carrying inner structure mounted at the stem of the vessel and an outer shell structure defining the hydrodynamic properties of the bulbous bow, wherein said outer shell structure is provided with a sub-structure for replaceably mounting on the inner structure. The invention further concerns a seagoing vessel comprising such bulbous bow as well as a method of producing a bulbous bow and a method of mounting or replacing a bulbous bow.

A method for installing a gantry tower crane for use in cargo tank checking is provided. By using this method, a tower crane can be installed rapidly since tower units are lowered when assembling the tower units, the time required to install two prefabricated towers can be reduced, and all zones of the cargo tanks can be checked as baskets, and pedestrian overpasses can be installed.

An offshore wind turbine blade and tower maintenance devices and systems, more particularly, to the system for service tools positioning relative to the offshore wind turbine blade and tower. An arrangement for lowering and raising service tools used for offshore wind turbine blade and tower maintenance, having: a truss system, a rigging and a rigging pulling in and letting out means. The truss system, includes booms, pivotally attached to a supporting means, which are adapted to be leaned against or releasably fixed to a wind turbine tower or wind turbine tower mooring elements; wherein the rigging and a rigging pulling in and letting out means are operably connected with the truss system, so to allow lowering and raising service tools used for offshore wind turbine blade and tower maintenance.
