Abstract: A pipeline termination skid to be mounted to a pipeline end section to support a pipeline hub during the connection of the pipeline hub to a corresponding spool piece hub. The pipeline termination skid is so designed that a pipeline end section may be mounted thereto subsea by lowering the pipeline end section into a seat of one or several holding devices of the pipeline termination skid and thereafter displacing the pipeline termination skid along the pipeline end section so that the respective seat is brought into engagement with an alignment element secured about the pipeline end section so as to thereby fix the pipeline end section axially and radially in relation to the pipeline termination skid. A connection arrangement includes the pipeline termination skid, a pipeline termination designed for co-operation with the termination skid and a method for subsea connection of a pipeline to a spool piece.

Abstract: A spool piece termination structure to be mounted to a spool piece so as to support a spool piece hub during the connection of the spool piece hub to a corresponding pipeline hub. The termination structure includes a clamping device for clamping together the spool piece hub and pipeline hub, and a base frame openly shaped downwards so as to allow the termination structure to receive a pipeline end section provided with the pipeline hub by lowering the termination structure downwards onto the pipeline end section. A connection arrangement includes such a spool piece termination structure and a method for subsea connection of a pipeline to a spool piece.

Abstract: Pipe system for subsea installations for offshore production or processing of hydrocarbons, for interconnection of or internal connections in functional units, such as Xmas trees (1) and manifold modules (2), where a pipe connection comprises communicating pipe branches (5,7,8) which run with mutual angle deviation or parallel to each other. A pipe branch (5) is provided with a bellows device (11) for obtaining a certain possibility of movement of the pipe branch, and a second pipe branch (7) is also provided with bellows device (12) for obtaining a certain possibility of movement of the second pipe branch (7).

Abstract: A method and a buoyancy device adapted to impart buoyancy to at least one longitudinal element submerged in water. The buoyancy device is hollow and is preferably made of plastic or a similarly corrosion-resistant material. The device is preferably produced as one single unit, but may include several separate chambers which, via valves, may be brought into communicating connection with the surroundings, in a controlled manner. The device will therefore not be subjected to large differential pressures in use, and accordingly may have relatively thin walls. The buoyancy device has a much lower weight than prior-art buoys, is simpler to assemble, and is not subject to corrosion.
