  • Publication number: 20060197339
    Abstract: A sealing element that includes a hollow body of metallic material and first and second male sealing members formed at a respective end of the body. The respective male sealing member has an external spherical contact surface designed for mating with a corresponding internal conical contact surface of a female sealing member so as to form a fluid-tight seal between the male sealing member and the female sealing member when their contact surfaces are pressed against each other. Also, a coupling device and a valve device provided with the sealing element.

  • Patent number: 7073404
    Abstract: A method and device for detecting an accumulation of a solid material in a vessel that contains at least one fluid phase. The device includes an electric conductor element that is positioned in a region inside the vessel where the accumulation is likely to occur, the electric resistance of the conductor element being a function of the temperature thereof, elements for providing electrical power to the conductor element and elements for repeatedly measuring the electrical resistance of the conductor element.

  • Patent number: 7048060
    Abstract: A subsea system for processing a fluid emanating from one or more subsea wells, comprising a fluid processing circuit and a base module (3) provided with at least one receiver (40) for receiving an insert module (4-8) comprising an appliance that forms part of the fluid processing circuit. The receiver (40) comprises a cavity (30) for accommodating the insert module (4-8). The insert module (4-8) is provided with a flange (31), which is adapted to bear on a corresponding flange (32) of the receiver (40) when the insert module (4-8) is mounted therein, a watertight seal (33) being arranged between said flanges (31, 32) so as to seal the space between the receiver (40) and the part of the insert module (4-8) received therein from the surrounding sea water.

  • Patent number: 7011152
    Abstract: A power supply assembly, which is placed subsea and is connected to an umbilical from a platform, supplies electrical power to subsea equipment. The power supply assembly supplies power during drilling operations to a pump for pumping drilling fluid from the sea floor to the sea surface. During production operations, the power supply assembly provides power to a booster pump to pump the well fluid away from the subsea well for collection. The subsea power supply assembly optionally also provides power to electrically charged portions of subsea separators that remove water from the oil in the well fluid. The booster pump the pumps the oil from the separator away from the subsea wellhead for collection.

  • Patent number: 6985061
    Abstract: An arrangement and a method for use in installation procedures for subsea transformers. A central, hole or tube is included in an encapsulation enclosing a transformer that is to be installed. Three core elements of the transformer are arranged symmetrically around the hole or tube forming a triangle or a delta. The transformer is lowered towards a a foundation placed on the sea floor wherein a guide pin is mounted. When the transformer has found its way to the foundation, the guide pin will enter the tube, and the transformer will slide down onto the guide line pin. The tube is terminated by a funnel shaped opening, thus making it easier not to miss the guide pin by the tube opening. The transformer is horizontally oriented by means of orientation keys localized within the tube.

  • Publication number: 20050116799
    Abstract: An electrical switching device including at least one ingoing conductor at least a first and a second outgoing conductor, and an arrangement for connecting and disconnecting the conductors by means of an axial movement. The arrangement includes an axially movable element, which is movable between a first and a second position. The device is arranged such that when the axially movable element is in the first position, the ingoing conductor and the first outgoing conductor are electrically connected, and the ingoing conductor and the second outgoing conductor (3) are disconnected. When the axially movable element is in the second position, the ingoing conductor and the first outgoing conductor are disconnected, and the ingoing conductor and the second outgoing conductor are electrically connected.
