Abstract:
A pipeline repair connector (40), for a sub sea pipeline repair system, arranged for connecting and disconnecting pipelines on the ocean floor. The invention also related to a system including a connector (40), and to a method for replacement of broken pipelines on the ocean floor.
Abstract:
A locking device (10) for assembling several parts is described, comprising an internal, open housing (12) that is equipped with internal, locking segments (20), an internal, open casing (14) for insertion into the housing (12) and which is equipped with external, locking segments (22) and internal, locking grooves (24), and a plug (16) for insertion into the casing (14) and which is equipped with external, locking grooves (26). The external, locking segments (22) of the casing (14) are corresponding to and opposite to the internal, locking segments (20) of the housing (12), and the internal, locking segments (20) of the housing (12) comprise an inclining, locking surface (20b), and the external, locking segments (22) of the casing (14) comprise an inclining, locking surface (22b), where said locking surfaces (20b, 22b) are forced against each other during retraction of the plug (16).

Abstract:
A pipeline repair connector (40), for a sub sea pipeline repair system, arranged for connecting and disconnecting pipelines on the ocean floor. The invention also related to a system including a connector (40), and to a method for replacement of broken pipelines on the ocean floor.
Abstract:
A method for replacement of broken pipelines on the ocean floor includes lowering a lifting and positioning tool from the surface down to the ocean floor. A first pipeline end is lifted and positioned on the ocean floor. A preparation tool is lowered from the surface down to the ocean floor, and said pipeline end is inserted into the preparation tool. The method comprises repairing radius and ovality defects, and milling the outer surface of the pipeline end. The method further includes lowering a first pipeline repair connector from the surface down to the ocean floor, and connecting the repair connector to said pipeline end. The steps of the method are repeated on another pipeline end for a second pipeline repair connector and the method comprises lowering a replacement pipeline to the ocean floor and clamping the ends of the replacement pipeline into each of the repair connectors.
