Provided are a floating structure fluid dynamic force use system and a wind-propelled vessel which uses the system whereby it is possible to compensate for overturning moment due to fluid dynamic force and to alleviate both tilting and size increases of a floating structure. A floating structure fluid dynamic force use system (1) comprises an assembly (12) which extracts energy from wind or water, and a floating structure (13) which supports the assembly (12). The assembly (12) comprises a wind receiving part (10) which receives fluid dynamic force, and a support column (11) which supports the wind receiving part (10) . The assembly (12) is positioned with the center of gravity (15) thereof below the water line.

A bottom-fixed wave energy capture device is provided and comprises a foundation and an oscillating water column energy collector device. The device comprises a collection chamber and the chamber includes means for changing a position of a surface of the chamber so there is an increased surface area against which waves coming from a generally opposite direction impact.

Vorrichtung zur Entlastung einer Tragstruktur einer Windenergieanlage, - mit einer Entlastungswandung (20), die dazu eingerichtet ist, die Tragstruktur (16) zumindest abschnittsweise umfangsseitig zu umhüllen, - wobei die Entlastungswandung (20) im fertig montierten Zustand ausgehend von einem fundament- oder gründungsseitigen Verankerungsbereich (22) in Richtung eines gondelseitigen Befestigungsbereichs (24) trichterförmig verjüngt ist.
摘要:
The present invention relates to an offshore wind turbine comprising a tower, where said wind turbine at a level above sea level comprises at least one structure for storing at least one container, said container having the size and measures of a standard container, where said structure is arranged on the side of the tower. The invention further comprises a method of manufacturing such a concrete structure for an offshore wind turbine. The structure for storing one or more containers according to the invention comprises a deck, and at least one bed for supporting at least one container along said containers lower surface and/or edges, where said structure is a concrete structure. By manufacturing said structure from concrete a very robust and strong structure is achieved.
摘要:
Tower for a wind energy device, including a lattice tower part (1) which has a polygonal cross section at least at a top, and a tubular tower part (2) extending thereabove which has a substantially circular cross section at a bottom, wherein the lattice tower part (1) and the tubular tower part (2) are coupled to each other by means of a transition body (3), wherein the lattice tower part (1) extends partly along the transition body (3), in a vertical direction, wherein the transition body (3) is provided with a lowermost part having a polygonal cross section adapted to the lattice tower part, as well as an uppermost part having a circular cross section adapted to the circular cross section of the tubular tower part.

摘要:
A transition element between a jacket having four legs and a tower where the lower portion of the tower is fixed to a torsion plate that is connected to an upper portion of the legs. A brace extends from each leg. Each brace includes a strut. The strut has a first end portion and a second end portion. The strut is fixed to the upper portion of each leg and a plate that is fixed to the tower at a contact portion above the torsion plate. The planar plate is fixed to the tower in the circumferential direction and has a common axis of symmetry with the strut. The plate is fixed to the first end portion of the strut.
