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.

Abstract: A permanent subsea sampling and analysis system is integrated into a replaceable equipment module for a choke valve of a subsea production well. The analysis system is self-contained, and 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 all in the same sampling container.

Abstract: The invention relates to a method for two-step separation of water, salt and particles from a hydraulic fluid by the use of a control unit. The hydraulic fluid is carried into a return oil tank with an electrostatic coalescer provided with a high-voltage transformer with direct current to two electric grids whose electrostatic field gathers water into drops which settle into a collecting tank. The hydraulic fluid is circulated to a filter module for removing any remaining water, salt and particles in filter elements connected in parallel, having hygroscopic cellulose fibers which swell until saturation, the swelling being measured by a sensor measuring the degree of saturation, alternatively conductivity.

Abstract: The invention relates to a method for production of a cylindrical acid proof, seamless pressure vessel having hemispherical top and bottom by powder moulding in an HIP (Hot Isostatic Pressing) process. Sheet metal moulds are produced constituting an internal shell (1), lower part of an external shell (3), upper part of an external shell (4) with filling spout (5) with corresponding top and bottom. Distance pins (2) decide the wall thickness and are mounted outward from the internal shell which is led down into the lower part of external shell (3) whereafter shell part (4) with filling spout (5) closes the volume be-tween the internal and external shells which is then filled with powder through the filling spout (5). The pressure vessel is placed in an HIP-process container for vacuuming, sealing, supply of high-pressure inert gas such as argon, at high temperature such as 1000 °C, for processing together with the distance pins (2) to a compact and homogenous material.

Abstract: The invention relates to a method for two-step separation of water, salt and particles from a hydraulic fluid by the use of a control unit (1). The hydraulic fluid is carried into a reservoir oil tank (4) with an electrostatic coalescer (3) provided with a high- voltage transformer (2) with direct current to two electric grids (43, 44) whose electrostatic field gathers water into drops which settle into a collecting tank (5). The hydraulic fluid is circulated to a filter module (9) for removing any remaining water, salt and particles in filter elements (92) connected in parallel, having hygroscopic cellulose fibres which swell until saturation, the swelling being measured by a sensor (93) measuring the degree of saturation, alternatively conductivity.
