A coupling system for temporarily coupling a jacket with a foundation pile includes a first flange for mounting with the jacket, a second flange for contacting the foundation pile, and an inflatable spacing member arranged between the first flange and second flange. The inflatable spacing member contacts both the first flange and second flange for supporting the jacket through the spacing member.

A wind turbine foundation comprising a concrete support slab having a horizontal rebar grid therein, a concrete pedestal integral with the support slab and having vertical post tensioning elements therein and a plurality of concrete ribs on top of and integral with the support slab and integral with the pedestal, the ribs having rebar therein and extend outwardly from the pedestal, the pedestal, slab and ribs are connected to each other to form a monolithic foundation. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.

A manufacturing facility for assembling a jacket structure 3 comprising a number of subcomponents 10, said subcomponents 10 including a prefabricated brace 12 and a pair of prefabricated legs 30, 30, wherein the manufacturing facility comprises a number of first supports 20 for supporting each of the prefabricated legs 30,30, a number of second supports 40 for supporting the prefabricated brace 12 and a welding unit for welding the prefabricated brace 12 to the prefabricated legs 30,30.

Disclosed is a method of manufacturing an offshore substation topside for assisting in transporting electricity generated by an offshore wind farm arranged at a first location to land. The offshore substation topside comprising a first deck and a first block arranged on the first deck, wherein the first block comprises a plurality of modules including a first module and a second module, each module of the plurality of modules comprises one or more standardized sections selected from a group of standardized section, each standardized section comprises a self-supporting frame. The first module of the plurality of modules is manufactured at a second location, the first module and the second module of the plurality of modules having at least one standardized section in common, and the plurality of modules being assembled into the first block at a location remote from the second location.

A wind turbine foundation comprising a concrete support slab having a horizontal rebar grid therein, a concrete pedestal integral with the support slab and having vertical post tensioning elements therein and a plurality of concrete ribs on top of and integral with the support slab and integral with the pedestal, the ribs having rebar therein and extend outwardly from the pedestal, the pedestal, slab and ribs are connected to each other to form a monolithic foundation. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.

The invention relates to a marine structure comprising a foundation system with three or more suction buckets. The suction buckets are designed to be installed in the seafloor to operate as a foundation or part of it to support an offshore structure resting onto the seafloor. The suction buckets support a connector body and the connector body is designed to support a payload. The invention also relates to a method of installing a suction bucket. During the method, the suction bucket bottom penetrates the seafloor and fluid is removed from the suction space such that penetration proceeds by suction.

The invention relates to a transition piece for connecting an upper tower portion with connection profiles of a lower tower portion. The invention further comprises the respective connection profiles. The transition piece is particularly suitable for a hybrid tower, e.g. for a wind turbine, wherein the upper tower portion is configured, for example, as a steel tubular tower and the lower tower portion as, for example, a lattice tower structure.

The present disclosure describes a base structural building module employing a core structural member having an array of upwardly and outwardly and downwardly and outwardly extending braces or arms extending therefrom. Tubular cans are mounted at the ends of each of the upper and lower arms to receive piles. One upper arm is aligned and paired with one lower arm and the pair's respective cans are aligned about their can axis. The modules employ flexible design by varying the lengths of the arms and their respective inclination or declination angles. Modules can be stacked one on top of another (and secured) to form multi-tiered structural building jackets for building vertical structures such as, for example, oil and gas platforms used onshore or offshore as well as other structures. Each tier can also comprise multiple modules joined laterally together to provide a wide variety of potential template configurations and building applications.

An offshore foundation structure includes a jacket portion having a plurality of struts interconnected in a framework-like manner, and a receiving means for a tower shaft of a wind power installation. The platform is arranged at least partially in the interior of the jacket portion. The offshore foundation structure also has a gangway and a lift.

The invention relates to a crane, such as a hoisting crane (3000) having a hoisting boom (3010) having a lifting region (3020), configured to lift a load (3050) and an actuatable restraint device (3040), the device extending from the crane. The actuatable restraint device is configured to engage with a load being lifted, so as to control movement of that load with respect to the lifting region in at least one direction. The actuatable restraint device may be configured to control movement in as much as inhibiting, or mitigating, certain movement.
