摘要： A method for protection of compressor modules against undesirable influx of contaminated gas, comprising a pressure housing (3) which by means of one of more sealing elements (4) is generally divided into a first compartment (8) equipped with a compressor (2) and a second compartment (7) equipped with a gas-filled motor (1), the compressor and the motor being drivably connected to each other by at least one shaft (9), is distinguished by protecting the second compartment (7) with motor (1) against direct influx of contaminated gas from the first compartment (8) with compressor (2) by means of compressed gas that is supplied from a withdrawal point (13) at the first or intermediate stage of the compressor, or from the compressor outlet (16), and by introducing the compressed gas directly into the seal (4) or in between two or more seals so as to flow through the at least one seal (4) back to the first compartment (8). The invention also relates to an apparatus for use in connection with the method.

摘要： An electrically operated hydraulic valve comprises a valve assembly that provides a common valve passageway, an inlet port, an outlet port and a return port connected to the passageway and an axially movable valve device which allows in a first position fluid flow between the outlet port and the return port while closing the inlet and in a second position, axially displaced from the first position, fluid flow between the inlet port and the outlet port while closing the return port. A spring provides a restoring force urging the valve device to its first position. An electrically operated actuator coupled to the valve device comprises a permanent magnet and a cooperating electrical coil having an associated magnetic core, one or other of the magnet and the coil constituting a stator and the other constituting an armature which is coupled to the valve device to move it from the first position to the second position. The actuator is disposed for operation by an electrical supply which provides a unidirectional current pulse to the coil.

摘要： A retrievable tree cap for use on a subsea tree having a concentric bore. The tree cap may be installed and retrieved using a remotely operated vehicle. Hydraulic pressure may be used to lock the tree cap onto the subsea tree and to set the tree cap seals. The tree cap is locked onto the subsea tree before setting the seals within the concentric bore. The tree cap includes a locking means that may engage a profile within the subsea tree regardless of the radial orientation of the tree cap. The tree cap may be used to hydraulically isolate an annulus bore from the production bore of the subsea tree. The tree cap may provide for the injection of a corrosion inhibitor within a cavity of the tree cap and may also provide for the removal of water trapped between the tree cap and the subsea tree.

摘要： The invention provides a gate valve (1) for control of petroleum production or water injection, distinctive in that at least one surface subject to slidng in operation of the valve comprises a top layer coating of diamond like carbon (DLC). The DLC contains hydrogen, preferably more than 16 atom-% and more preferred more than 17 atom-%. It is further directed to a method of commissioning or operating a gate valve according to the invention, and use of a diamond like carbon (DLC) top layer coating on at least one surface subject to sliding in operation of the gate valve. Valve parts have a tendency of sticking, adhering or cold welding together, which result in high friction. The aim of the invention is to reduce or eliminate friction problems occurring with time or operation cycles, when using a full scale gate valve.

摘要： System and method for control of a subsea located cyclone for separating oil from water. The cyclone is arranged to receive water with oil contents through an inlet line, the oil is separated from the water and delivered through an oil outlet to an oil outlet line, and the water is delivered through a water outlet to a water outlet line. The system is comprising a control valve in the oil outlet or oil outlet line from the cyclone, a first differential pressure transducer arranged between the inlet line and the oil outlet from the cyclone, and a second differential pressure transducer arranged between the inlet line and the water outlet from the cyclone. The system is distinguished in that a sensor for measuring oil contents is arranged in the water outlet or water outlet line, and via a control means said sensor is operatively connected to the control valve.

摘要： The invention provides a subsea pressure boosting system feasible for operation at subsea step out lengths above 40 km and by control merely from a dry topside or onshore location. The system is distinctive in that it comprises: at least one subsea power step out cable, arranged from a near end at a dry location onshore or topsides to one or more subsea loads such as subsea pumps or subsea compressors at a far end, at the near end at least one source for electric power is connected and the cable is dimensioned for operation at a frequency different from the operation frequency of the connected subsea loads in order to handle the Ferranti effect and electric losses, and at least one passive electric frequency transformer, operatively connected between the subsea step out cable far end and the subsea loads, said transformer is located in a pressure vessel and transforms the operation frequency of the subsea step out cable to a frequency feasible for operation of the connected loads.
