Abstract: A multi-use fully restrained platform system for offshore marine applications includes a monopile foundation, an interface piece mounted atop the monopile, and a deck structure coupled to the interface piece. The interface piece provides a standardized connection mechanism that enables various payload configurations to be mounted on the same foundational infrastructure, including wind turbines, oil and gas extraction equipment, hydrogen production facilities, offshore charging stations, electrical substations, offshore datacenters, and marine infrastructure such as bridges. The interface piece includes multiple receptacles configured to receive mounting columns from the deck structure, with the receptacles arranged to accommodate different deck geometries and payload requirements.

Abstract: An apparatus and a method for guiding multi-diameter cables onto a drum by means of a cable guide device. The cable guide device includes a guiding means translationally moveable along a linear actuator, and the guiding means has an opening with a minimum spacing in a direction along the orientation of the linear actuator that is larger than the maximum cross-section of a cable to be guided inside the opening of the guiding means. Further, a cable, during use, is, most of its operational time, contacting at least one of at least two barriers, and the barriers constitute at least part of a confinement of the opening in the orientation of the linear actuator. The cable guide ensures rapid contact recuperation after loss or near loss of cable contact on one or more of the at least two barriers.

Abstract: A coupling device for connecting a first coupling housing and a second coupling housing. The first coupling housing has a guiding element extending from the first coupling housing and having a free end at a distance (h) from the first coupling housing central axis (a-a). The second coupling housing has a receptacle for the guiding element and pull-in means for pulling the guiding element into the receptacle, said pull-in means being connected to the guiding element free end. The invention allows the first coupling housing to be pulled towards the receptacle at an angle which is not coincident with the central axis (a-a), and when the guiding element is in place inside the receptacle, the first coupling housing central axis (a-a) and the central axis (b-b) of the second coupling housing are aligned and coincident, and the two housings are rotationally aligned.

Abstract: A coupling device for connecting a first coupling housing (12) and a second coupling housing (20) is provided. The first coupling housing (12) comprises a guiding element (101; 201; 301a-e; 401b,c; 501b-d) extending from the first coupling housing (12) and having a free end (102; 202; P) at a distance (h) from the first coupling housing central axis (a-a). The second coupling housing (20) comprises a receptacle (123; 223; 323; 423; 523) for the guiding element and pull-in means (8) for pulling the guiding element into the receptacle, said pull-in means (8) being connected to the guiding element free end (102; 202; P). The invention allows the first coupling housing to be pulled towards the receptacle at an angle which is not coincident with the central axis (a-a), and when the guiding element is in place inside the receptacle, the first coupling housing central axis (a-a) and the central axis (b-b) of the second coupling housing are aligned and coincident, and the two housings are rotationally aligned.

Abstract: A mooring arrangement for a semi-submersible offshore structure having an outer hull with a lower (2) and an upper (1) water line, comprises a mooring line (4) extending from a fixed point on the seabed to an attachment on the offshore structure, at least a portion of the mooring line closest to the attachment being a chain. The attachment comprises a hawse (10) and a chain stopper (22) located below the lower water line. The chain stopper (22) is located in a dry space inside the outer hull and is sealingly attached at one end to the hawse and at the opposite end to a chain pipe (9) which extends inside the hull to above the upper water line. The hawse extends outwards from the chain stopper and is sealed to an opening in the outer hull.

Abstract: A device for heaving in and paying out a chain by means of a hydraulic cylinder which by means of gripping devices engages the chain and lifts or lowers the chain a given distance while the locking device is deactivated. The structure comprises a frame provided with a lower locking device, a chain wheel guiding the chain, and an upper gripping device mounted in a bracket which is connected to the rod head of the hydraulic cylinder and the central axle of the chain wheel. The lower locking device is formed by two pawls which are pivotally mounted on separate pins. These pawls engage under a chain link and hold it securely. The upper gripping device is formed by at least one pawl which, together with a chain wheel having pockets for the chain, engages under a vertical chain link.
