    Abstract: Structure and method for decommissioning offshore platforms presenting topsides (12) mounted on a jacket having a plurality of jacket legs. The offshore decommissioning structure comprises a jack-up-vessel (1) comprising a hull, a main deck (5), an elevating jacking device and a plurality of jack-up legs, wherein said jack-up vessel (1) is elevated on its legs above the sea level by the elevating jacking device. Furthermore, the structure comprises a carrying and skidding system for shifting the topsides (12)from the platform jacket onto the main deck (5) of the jack-up vessel (1).Besides, the method comprises the following steps: position the jack-up vessel (1) close to the platform (12); position skid beams (18) on jack-up main deck (5) relative to the platform legs; push jacket skid beams toward the jacket legs;cut the platform jacket legs below the topside (12); and shift the topsides (12) on the skid beams (18) to the jack-up main deck (5).

    Abstract: Die Erfindung betrifft ein Verfahren zur Bildung einer Verbindung (3,20) zwischen zwei Rohrsegmenten (1,2,21,22) unterschiedlicher Weite, vorzugsweise eines turmartigen Bauwerks, insbesondere einer Windkraftanlage. Um Rohrsegmente unterschiedlicher Weite einfacher, zuverlässiger und kostengünstiger miteinander verbinden zu können, ist vorgesehen, dass das weitere Rohrsegment (1,31) mit einem Ende teilweise über ein Ende des schmaleren Rohrsegments (2,32) geschoben wird, dass die Rohrsegmente (1,2,21,22) unter Ausbildung eines Ringspalts (5,27) zwischen den Rohrsegmenten (1,2,21,22) voneinander beabstandet positioniert werden, dass im Ringspalt (5,27) zwischen den beiden Rohrsegmenten (1,2,21,22) eine sich in Längsrichtung (L) der Rohrsegmente (1,2,21,22) und/oder in radialer Richtung (R) erstreckende Trennschicht (4,14) vorgesehen wird, dass der Ringspalt (5,27) angrenzend zu der Trennschicht (4,14) und zu wenigstens einer Seite der Trennschicht (4,14) wenigstens teilweise mit einer Vergussmasse (9,30) ausgegossen wird, dass beim Aushärten der Vergussmasse (9,30) die Vergussmasse (9,30) auf einer Seite der Trennschicht (4,14) nur mit einem der Rohrsegmente (1,2,21,22) und/oder die Vergussmasse (9,30) auf der anderen Seite der Vergussmasse (9,30) nur mit dem anderen Rohrsegment (1,2,21,22) eine feste Verbindung (3,20) eingeht und dass die Rohrsegmente (1,2,21,22) nach dem Aushärten der Vergussmasse (9,30) mit den zugehörigen, insbesondere durch die ausgehärtete Vergussmasse (9,30) gebildeten, separaten Verbindungselementen (10,11,21,22) wieder entlang der Trennschicht (4,14) voneinander getrennt werden.

    Abstract: A foundation (1) for a structure. The foundation (1) has a body (2) for insertion into a soil in a insertion direction during installation. The body (2) has a toe (8) at its distal end. The toe (2) defines an aperture (11) into an internal cavity (15). Movement of the toe (2) through the soil displaces soil laterally into a displaced soil region within the internal cavity (15). One or more nozzles (10) are provided for directing a fluid to the displaced soil region during installation for transporting soil away from the displaced soil region. A pumping system (24) is also provided for evacuating fluid from the internal cavity (15) during installation for reducing the soil suspension pressure within the displaced soil region.

    Abstract: A method for permanent plug and abandonment of one or more offshore platform wellbores of an offshore platform and for decommissioning of said offshore platform, wherein said platform has a jacket and a topsides. Use is made of a marine jack-up type vessel. The method comprises: - arranging the vessel adjacent the offshore platform bringing the vessel in an operational position wherein the cantilever is movable in an extended position above the topsides of the offshore platform, - moving the cantilever into said extended position above the topsides and aligning the wellbore activities station with a wellbore, - performing a plug and abandonment operation involving the use of the wellbore activities station, - retracting the cantilever, - disconnecting the topsides from the jacket, - lifting the topsides from the jacket and placing said topsides on board the vessel, - operating the elevating units so as to lower the hull of the vessel into the sea and to retract the jack-up legs upward.
