    Abstract: The invention concerns a method of producing various massive blanks of encapsulated pipe connections by pressure moulding metal powder material, such as an encapsulated manifold (1) on a base plate (2). In an open mould of steel plates are installed a planned network of both curved and straight pipes (4) both for fluids, via a series of control valves (3) to a control module for hydraulic couplings, and for through pipes (5) for couplings for hydraulic and electrical distribution. From holes in the mould walls pipe ends are extending, which are sealed to the holes in the mould plates. External plates entered on to pipe connectors and locked before the HIP process hold the geometry of the piping network. When the network of pipe and cable connections is established, the top plate is sealed to the mould. A flexible steel bellows is fastened to the top plate, and is used to fill the mould with casting powder and for replenishing to eliminate volumetric shrinkage in the mould during the HIP process, whereafter the mould is removed, and the cast blank is machined before external pipe network and cable connections are connected.

    Abstract: The Invention concerns a permanent subsea sampling and analysis system (1), which typically is integrated into a replaceable equipment module for a choke valve (2) of a subsea production well. The analysis system (1) separates a sample into liquid fractions consisting of crude oil, condensate and produced water and then measures the salinity of the water as well as the volumetric ratio between the liquid fractions. With this equipment it will be possible to check, at regular intervals, the development in salinity of the produced water from a singular well without disturbing the production from the well. The information from the analysis system (1) may be used to update the calibration set-up of the multiphase flow meter of the well, or to reveal a possible water breakthrough resulting from water injection into a reservoir, or for other reservoir analyses. Due to the analysis equipment becoming permanently installed on the subsea well equipment, costs of taking samples via intervention operations from vessels are avoided, also avoiding temporary shut-down of production from other wells producing to a joint subsea manifold for the purpose of investigating which well may possibly have experienced water breakthrough.

    Abstract: The invention relates to a method of using new flushing ports (1A, 1B) when cleaning a piston accumulator (7). Dirty hydraulic oil is returned out via the main port (2) and a return passage (9) until a cleanness grade has been reached. Clean hydraulic oil is forced into the piston accumulator (7) via the axial bores (3A, B) of the flushing ports (1A, B) and further in sloping bores (3C, D), bringing the hydraulic oil into the volume (8) in an upward, tangential direction below the piston (5), into a flushing circulation. By reducing the gas pressure on the gas side (4) of the piston (5) in relation to flushing pressure input from a valve (6), a volume (8) is created on the oil side between the piston (5) and the end bottom (3). The return passage (9) is closed and the piston (5) is brought into its upper position, so that an internal cylinder wall (10) is cleaned. Upon pressure build-up, the return passage (9) is opened, and the piston (5) returns to its end position on the oil side while the supply of clean hydraulic oil is maintained, and the operation is repeated until a clean-ness grade has been achieved.
