20090317265 | METHOD AND APPARATUS FOR PROTECTION OF COMPRESSOR MODULES AGAINST INFLUX OF CONTAMINATED GAS - A method for protection of compressor modules against undesirable influx of contaminated gas, comprising a pressure housing ( | 12-24-2009 |
20090266553 | APPARATUS AND METHOD FOR PREVENTING THE PENETRATION OF SEAWATER INTO A COMPRESSOR MODULE DURING LOWERING TO OR RETRIEVAL FROM THE SEABED - An apparatus for preventing seawater from penetrating into a compressor module during lowering to or retrieval from a compression plant on the seabed, with optional discharge of residual production fluids, as for instance hydrocarbons, from the compressor module prior to retrieval, wherein the compressor module comprises an electric motor ( | 10-29-2009 |
20090050326 | Device and Method for Cleaning a Compressor - A system for cleaning compressors ( | 02-26-2009 |
20090020061 | Connector for Releasable Connection Between an Achorage in the Form of a Female Part Arranged on a Floating Means and a Male Part Formed at the End of a Retrievable Umbilical - A connector ( | 01-22-2009 |
20080260539 | Apparatus and Method For Controlling Supply of Barrier Gas in a Compressor Module - An apparatus for controlling the supply of barrier gas to a compressor module includes a pressure housing containing an electric motor which via a shaft is drivably connected to a compressor. The shaft is supported by magnetic bearings and at least one axial seal around the shaft which divides the pressure housing into first and second compartments including the motor and compressor, respectively. The second compartment has fluid inlet and outlet. A line is fluid-connected to the first compartment for barrier gas from a reservoir, with a flow restriction element between the reservoir and first compartment. The apparatus facilitates a method for controlling the supply of barrier gas based on gas velocity through the seal and pressure in the second compartment. An overpressure can be set in the reservoir. A controlled supply of barrier gas to at least the first compartment is effected via flow restriction in the feed pipe. | 10-23-2008 |
