Abstract: A jacket 4 for an offshore structure comprises a plurality of jacket modules 6 stacked one above the other, each of the jacket modules having multiple hollow legs 10; and a plurality of piles 8 passing through the hollow legs 10 for securing the jacket 4 to the sea-bed; wherein the piles 8 include: foundation piles 8a passing through legs 10 of a lowermost jacket module 6a, with a lower part of each foundation pile extending downward below the lowermost jacket module 6a into the sea-bed, and an upper part of each foundation pile extending upward out of the tops of the legs 10 of the lowermost jacket module 6a and into legs 10 of a second jacket module 6b located atop the lowermost jacket module 6a such that the upper parts of the foundation piles 8a extend into the legs 10 of the second jacket module 6b by a height less than the height of the jacket modules 6; and follower piles 8b within the legs 10 of the second jacket module 6b located atop the upper parts of the foundation piles 8a and extending upward ou

Abstract: The present invention concerns a floating wind power apparatus with a floating unit and at least three rotors supported in rotor housings, placed on separate towers with a longitudinal central axis. The towers are attached in the floating unit and the rotor housing, and the floating unit may yaw to direct the rotors in relation to the wind. At least one rotor is a downwind rotor, and at least one rotor is an upwind rotor. The towers are placed at an inclined angle in relation to the rotors.

Abstract: A production platform for offshore exploitation of hydrocarbons comprises a truss tower (1) which rests on the sea floor (2) and supports a deck structure (3) provided with a drilling module (5). In order to obtain optimum mutual distance between production pipes (10) at the deck level, the skid beams (6) of the drilling module are arranged parallel to a diagonal (9) in the cross-section of the truss tower. Weight savings in the truss tower (1) may be obtained by arranging the deck structure (3) with its sides parallel to the diagonals (9) of the truss tower (1).

Abstract: The present invention relates to a joint for trusses having members comprising tube-like hollow bodies, comprising a core member to which is welded a plurality of transition pieces to which free end a tubular member can be welded, the cross section of the transition pieces changing between the free end of these and the end which is welded to the core member.
