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 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 use in a method for removing a jacket for an offshore platform includes an oblong structure rotatable by ballasting, with a sliding saddle which is movable in the longitudinal direction of the oblong structure and adapted for securing the jacket, thus enabling the jacket to be moved in relation to the transporter by the sliding saddle after being attached to the sliding saddle and released from the seabed.

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.
