  • Patent number: 6997645
    Abstract: A subsea tool (10) designed to pull pipeline ends (PE1, PE2) towards each other is disclosed. The tool (10) comprises a first and a second main body (1, 2) that are able to be displaced to and from each other and have limited freedom of motion relative to each other. The first main body (1) comprises a frame construction (5) having means (11b) for guiding onto and fixed attachment to one of the pipeline ends (PE1). The second main body (2) comprises a frame structure (6) having means (18) for guiding onto and retaining the other pipeline end (PE2). A number of guiding means (15, 16) are provided on the first main body (1) for co-operation with complementary guiding elements (20, 21) provided on the second main body (2). A pulling device (3) is arranged between the first and second main body (1, 2) and is designed for pulling the main bodies (1, 2) including the respective pipeline ends (PE1, PE2) towards each other.

  • Patent number: 5501549
    Abstract: A tool for the remote-controlled pulling, aligning and connecting of a subsea conduit to a subsea installation. The tool includes a framework, a pulling wire with a pulling head which can be releasably attached to the end of the subsea conduit and also optionally aligning means which bring the ends of the conduit which are to be connected in line with one another. The tool has a frame pivotally mounted on the framework around a substantially horizontal axis oriented substantially at right angle to the axis of the conduit and at almost the same height at which the conduit will finally lie, said frame including a grip elevator which can grip and hold the pulled conduit and manipulate the end of the conduit between a slanting pulling position and a final substantially horizontal connecting position.

  • Patent number: 4594696
    Abstract: A means for terminating of splicing a cable intended for towing air-water guns behind a seismic vessel. The end of the cable, or of each cable section, is guided into the housing of the termination member. The termination is formed with separately located connection sites for the cable components. The cable's tension-relieving wires (3) are guided into a first chamber (I) in the housing and fastened to the supporting structure of the chamber (I), i.e., the housing. The chamber (I) is filled with a water-repellant lubricant. The cable's conductors (9) are guided individually through the first chamber (I) and through a sealed passage (10) in a wall (14) defining a second, watertight chamber (II) which is filled with an electrically insulating, hydrophobic, water-emulsifying liquid. The chamber (II) is also provided with a pressure compensator (8).
