  • Patent number: 10167061
    Abstract: A buoyancy device (1) comprises a support structure 2, which can be connected to an underwater application (3) and one or more buoyancy spheres (4) having a specific weight of less than 500 kg/m3 connected to the support structure (2) and having a light metal spherical shell (5) defining a spherical inner volume (6) and which has an outer diameter (d) greater than 0.5 cm, and a radial thickness (t) greater than 0.08 mm, wherein the spherical shell (5) is obtained in one piece in nano-crystalline metal with an average grain size of less than 1000 nanometers.

  • Patent number: 10166714
    Abstract: A roller for compressing protective sheeting of polymer material around a pipeline rotates about a given or designated axis of rotation and has a shaft; and a first tubular portion which extends about the shaft and varies in elasticity along the given or designated axis of rotation; more specifically, the first tubular portion is of greater elasticity at the ends of the roller than at the center of the roller.

  • Patent number: 9388919
    Abstract: A method of abandoning a pipeline from an offshore vessel, wherein the method includes the steps of: providing a tubular member between a winch apparatus and the end of the pipeline being abandoned, the tubular member being received in a tensioning apparatus, and lowering the pipeline with the winch apparatus and the tensioning apparatus, the tensional load of the pipeline being held by the tensioning apparatus and the winch apparatus at the same time.

  • Patent number: 8998533
    Abstract: A method of laying pipeline from a vessel (10) is disclosed. The vessel (10) includes many pipe processing stations (36, 42), arranged across the width of the vessel. In one embodiment, there are two pipe processing areas (38, 40) separated along the length of the vessel. The pipe processing stations (36, 42) may be operable in two modes of operation, for example, a first mode of operation where the vessel produces triple joint pipe strings (from three lengths of pipe section welded together) and a second mode of operation where double joint pipe strings are produced, for example, from two single length pipe sections having a significantly greater length than the single length pipe sections used in the first mode of operation. In one embodiment, a triple joint pipe section is part welded in one pipe processing area (38), then moved along the length of the vessel (10) to a different pipe processing area, where further welding operations are performed on the triple joint.

  • Patent number: 8106327
    Abstract: The present invention relates to a welding torch that includes an electrode (3) that has a longitudinal groove (9) formed therein which guides a welding wire (4) which is fed form a laterally spaced-apart location. The electrode (3) is open and the wire (4) is supported on one side only. In the region of the welding tip, the electrode (3) is elongate and the cross-sectional area is smaller than the area at a position further from the tip. Regions between an outer housing (11) and a main support body (2) define two shielding gas conduits positioned on opposite sides of the body (2), through which gas flows and then combines to form a unitary stream. The body (2) contains cooled regions which are supplied with cooling fluid by a conduit (7) and removed by conduit (8), parts of which are positioned between the shielding gas conduits close to the welding electrode (3).
