Abstract: 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.

Abstract: A method controls force 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. The method may include 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 at 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.

Abstract: A stayed connection for a wind turbine (1) is provided with a tower (4) having an upper pipe-shaped tower portion (12) and a lower tower portion (14) and where the upper pipe-shaped tower portion (12) is connected to the lower tower portion (14) by means of a stayed connection (16), and wherein the stayed connection (16) comprises pipe-shaped diagonal stays (18) extending from the lower tower portion (14) and in toward the outside of the upper pipe-shaped tower portion (12), as the diagonal stays (18) at their toward the upper pipe-shaped tower portion (12) facing end portion (28) are compressed and connected directly or via a plate portion (30) to the upper pipe-shaped tower portion (12) by means of a welded connection.

Abstract: 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.

Abstract: 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.

Abstract: 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).

Abstract: A transporter for removing an offshore platform has an oblong structure with a U-shaped cross section, rotatable by ballasting. The transporter is adapted to remove and carry both a jacket and a topsides simultaneously.

Abstract: A transporter for heavy objects at sea comprises an oblong structure with a U-shaped cross section and a prismatic enveloping surface, and comprises two long sides, an intermediate underside, an opposite open top side and two short sides. Ballasting chambers are arranged in each of the structure's eight corners which are formed by the points of intersection between the long sides, the underside, the open top side and the short sides, whereby the structure can be rotated by ballasting to a desired position in the water.

Abstract: The jackable oil rig employs a leg formed of a plurality of corner columns and transverse stays. Each column is formed of an outer pipe, and inner pipe which defines an annular space with the outer pipe and a hardenable material such as concrete in the space between the pipes. The outer pipe has a constant outer diameter along the length while the inner pipe has a constant outer diameter along the length and an increasing wall thickness from a top section to a bottom section. The wall thickness of the inner pipe may increase step by step from about 30 millimeters in the upper section to about 150 millimeters in the lower section. The construction of the corner column allows oil rigs to operate at ocean depths down to 200 meters.
