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.

A support (4) for an elevated mass (6, 8), comprising at least three extended, mutually trussless supporting counts (14, 14′, 14″, 14′″), and where the longitudinal axes of the supporting columns (14, 14′, 14″, 14′″) meet near the center of gravity (20) of the elevated mass (6, 8).

There is described apparatus for use in installing a substructure 1 i.e. substructures for supporting offshore wind turbine towers. The apparatus comprises a positioning device i.e. a jack 115 attached to a leg 4a, 4b of the substructure. The substructure comprises at least one leg to be mounted to at least one base 114, and the at least one jack supports the leg upon the base, such that at least part of the weight of the substructure is supported on the base via the jack. In this way, relative movement between the leg and the base can be reduced, to allow a permanent mounting of the leg to the base by using a curable material such as concrete. A later embodiment relates to a method for installing a substructure comprising a jack coupled to at least one leg, wherein the jack cushions the substructure during landing.

摘要:
A device for a diagonal strut connection between a pipe (12) and an adjacent structure (14) including at least two diagonal struts (16), in which horizontal and vertical forces in the pipe are transmitted to the diagonal strut by means of a first set of shear forces along the attachment of the diagonal strut (16) to the pipe (12) and via a second set of shear forces along the attachment of the diagonal strut to an annular plate (18) surrounding and projecting radially from the pipe (12), the central axis of the diagonal strut (16) extending through or close to the intersection of the resultants of the first and the second sets of shear forces.

摘要:
A method for controlling power transmission between a structure and its base during grouting- in the fastening parts of the structure in the corresponding bases on or in the seabed, and where the method is characterised by comprising: - connecting a bracket to at least one of the fastening parts of the structure; - arranging an elastic material on the bracket; - displacing the fastening part to an overlapping position with the base until the elastic material transmits a least a portion of the weight of the structure to the base; and - filling an opening between the fastening part and the base with a curable mass.
