摘要:
A node structure (12, 14) for connecting two or more convergent members (16, 26) of a lattice frame to each other and to one or more other members of the lattice frame. The node structure (12, 14) comprises a pair of opposed spaced-apart faces (30) that are substantially planar and substantially parallel to each other. At least one pair of root formations (32) with respective central longitudinal axes define an interior angle between them, those axes diverging outwardly for alignment with respective members of the lattice frame and converging inwardly between the faces (30). An inner connecting wall (34) between the root formations (32) of the pair connects concave-curved inner edges (36) of the faces and extends in a concave curve around the interior angle to join the root formations (32) of that pair.

A jackup deployed riser protection structure comprises a plurality of coupler receivers disposed onto a jackup hull, a tubular sleeve, wherein the tubular sleeve is a hollow structure that allows a riser to pass through, a support structure coupled with the tubular sleeve to provide support for the tubular sleeve, and a plurality of couplers coupled with the support structure, wherein each of the plurality of couplers is coupled with one of the plurality of coupler receivers, so that the jackup deployed riser protection structure is supported by the jackup hull in order to provide protection to the riser.
摘要:
A node structure for connecting a member of a lattice frame to one or more other members of the frame comprises a hollow brace having opposed walls that converge outwardly at an acute angle in cross-section toward a central plane to connect at an outer edge. At least one root portion has a central longitudinal axis extending outwardly in the central plane of the brace for alignment with a member of the frame. The root portion has an inner end cut away at opposite sides around the central plane to leave a joining surface that intersects the converging walls of the brace while embracing an outer region of the brace extending inwardly from the outer edge.
摘要:
It comprises at least one substantially elongated pin associated with a wind turbine tower and at least one corresponding substantially elongated pile to be inserted into a surface and adapted for receiving at least one portion of the pin. A chamber is defined between the pin and the pile for receiving grout. At least one of the pin and the pile is provided with connecting plates extending inside the grouting chamber and provided with holes through which the grout passes. The connecting plates may extend radially inside the grouting chamber, aligned or not to each other or with the center of the pin or the pile.
摘要:
A jacket assembly guide for assembling a jacket structure is provided. The jacket structure includes a plurality of legs, a plurality of connecting braces and a plurality of node elements arranged on the legs for connecting the braces to the legs. The assembly guide includes a plurality of supporting towers for supporting the plurality of legs such that a supported leg is held in a position corresponding to the position of that leg in the assembled state of the jacket structure. The assembly guide further includes a plurality of connecting devices for releasably connecting one of the legs to one of the supporting towers.
摘要:
A floating offshore wind turbine comprises a rotor with a plurality of blades, a nacelle and a nacelle support structure having a central longitudinal axis. A plurality of tuned mass damping configurations is arranged around the central longitudinal axis of the nacelle support structure to dampen vibrations in all 6 degrees of freedom.
摘要:
A method of installing an offshore wind turbine and a transport vessel for use therewith in which a part of a wind turbine is secured to the transport vessel by raising the part in a perpendicular direction relative to the transport vessel into a transport position using a lifting device arranged on the transport vessel at a loading site. The transport vessel is then moved from the loading site out to an installation site. The transport vessel is secured to an offshore foundation which is located at the installation site. The wind turbine is then lowered onto an upper part of the offshore foundation using the lifting means. Finally, the transport vessel is released and moved away. This method eliminates the need for specially designed installation vessels using a crane to install an offshore wind turbine, thereby reducing the total installation costs.
摘要:
A transition structure for transitioning between two adjacent tower structures of a wind turbine is disclosed. The transition structure may include a plurality of vertical legs spaced apart from one another, a stub section positioned between an upper tower portion and a lower tower portion, a plurality of connecting members, each of the plurality of connecting members connecting one of the plurality of vertical legs to the stub section, and at least one torsion plate positioned between the plurality of vertical legs and the stub section.
