摘要： It is a pig launcher (1) comprising a pig magazine (2), launcher mechanism (3) and a connector (7) being connectable to a fluid flow line. The pig magazine (2) is able to hold a number of pigs arranged side by side, control lines (4) being connected to the pig magazine in such a way that each control line (4) is able to provide control fluid to manipulate a pig. The pig launcher further comprises a pig selector (5) being able to receive source control fluid from one control fluid source line (9) and to channel the control fluid to one of a number of control lines (4) being connected to the pig selector, thereby being able to launch one of the number of pigs by means of the control fluid.

摘要： A male-male hot stab assembly connectable to a flying receptacle is described. The male-male hot stab assembly comprises a first hot stab comprising a first hot stab male front end and a first hot stab base end, a second hot stab comprising a second hot stab male front end and a second hot stab base end, where the first hot stab and second hot stab are connected to each other by connecting the first hot stab base end to the second hot stab base end. In addition, a flying receptacle configured to receive a first hot stab of the hot stab assembly is described, which comprises a receptacle first end, configured to receive a first hot stab, a channel allowing the first hot stab to be inserted into the flying receptacle, a receptacle second end, and an ROY-handle. Further described is a subsea fluid connection system.

摘要： The present invention provides a CNC-parameter generating method in an isometric projection environment for the control and processing of tubes by at least one CNC-tube bending machine at least comprising: i) to generate a first vector on a touch screen; ii) to carry out a verification step by a microprocessor, iii) to assign the first vector to one of the directions, NORTH, UP, WEST, SOUTH, DOWN and EAST; iv) to generate further vectors by tapping once on the touch screen; v) to input dimensional values for the vectors on the touch screen, and to transfer dimensional values from the microprocessor device to one or more computers. It is also provided a parameter generating system in an isometric projection environment for the control and processing of tubes by at least one CNC-tube bending machine.

摘要： A system and modular compressor for raising the pressure in production gas is disclosed, wherein in a set of compressor modules each second module is a rotor module carrying an impeller driven in rotation relative to an adjacent stationary module, a rotor module and a stationary module in combination providing a compressor stage in which production gas is accelerated through a flow duct that passes an interface between the rotor module and the stationary module, wherein at the interface at least one bearing for axial and/or radial load is provided for journaling the rotor module on the stationary module. The at least one bearing is a gas bearing, wherein a passage is arranged in the stationary module to lead an extracted portion of production gas at raised pressure from the compressor to the gas bearing(s).

摘要： Methods and arrangements are provided for release of an ROV operable subsea clamp connector, the clamp connector comprising at least two clamp segments hinged to move pivotally, and a drive screw connecting the clamp segments by threaded engagement with trunnions arranged rotatable in the pivoting ends of the clamp segments, the threads of the drive screw and trunnions turned such that the trunnions travel along the drive screw in mutually opposite directions when the drive screw is turned. An axial bore in the drive screw is adapted for accommodation of a waterjet cutting tool having a sideways pointing nozzle in a forward end, the waterjet cutting tool rotatable inside the bore while feeding high-pressure water through the nozzle, towards the wall of the drive screw until the wall of the drive screw is cut through.
