Abstract: This invention relates to a system for loading or unloading a ship at sea, in particular for operations in connection with oil and gas activity, whereby the ship concerned is equipped with a mooring device at its bow. There is included an anchor device located at the seabed, and at least one anchoring line adapted to connect the anchor device to the mooring device on the ship. A permanent anchor device is provided with a swivel device for the anchoring line, and a buoyant body is attached to a middle portion of the anchoring line. Moreover, there is provided a hose connected to the swivel device and to the ship, for loading or unloading operations.

Abstract: A rotating coupling device or connector for interconnection between a number of risers (12) suspended from a submerged buoy and a pipe system on a floating vessel for the production of hydrocarbons, comprising a swivel unit consisting of a pair of concentric swivel members (20, 21) in the form of a male member (20) and a female member (21) defining mutually sealed annuluses (22) communicating with associated fluid paths (16) between the topical risers (12) and the pipe system on the vessel. The female member (21) is adapted for non-rotatable attachment to the vessel. The male member comprises a number of axially extending pipes (24) which, at their upper ends are connected to respective annuluses (22) and at their lower ends comprise a releasable connection (25) with fluid paths (16) leading to the respective risers (12).

Abstract: In a hull the skin plate is built up as a composite member with an outer skin, a core and an inner skin. The skin plate is placed on the framework which includes longitudinal stiffeners. The inner skin is constructed as a diaphragm element relative to the external water pressure, while the core is made as a pressure-absorbing element and the outer skin is constructed primarily as a bending stressed element. The inner skin as a diaphragm will take tensile stress and be protected against outer local stresses. The material in the core can be chosen without major requirements to be able to tolerate shearing stress. The outer skin can be dimensioned and made primarily to take local shock loads.
