Aker Solutions ASA, a Norwegian oil services company headquartered in Oslo, provides oilfield products, systems and services for customers in the oil and gas industry worldwide. The company, with roots back to 1841, was known as Aker Kværner prior to 2008.The predecessor company, Aker Kværner was founded in 2004 as the result of a major restructuring of a complex 'Aker Kværner' business unit, formed originally in 2002 by the merger of Aker Maritime and Kværner Oil & Gas. On 3 April 2008, Aker Kværner was renamed Aker Solutions, partly due to the difficulty that most non-Norwegian people found in pronouncing "Kværner".The company was majority controlled by Aker ASA until 2007. Through a major ownership restructuring on 22 June 2007, Aker ASA completely exited its holding in Aker solutions, and transferred a 40% stake to Aker Holding - which in turn owned by Aker ASA , the Norwegian Ministry of Trade and Industry , SAAB and Investor AB .The company employs approximately 28,500 people in more than 30 countries. It has annual revenues of approximately NOK 44.9 billion. Wikipedia.

A method for generation of electrical power and/or steam or vapour, by combustion of carbonaceous fuels, where carbonaceous fuel is combusted in a combustion chamber at a pressure of 40 to 200 bar in the presence of oxygen enriched air or substantially pure oxygen to produce electrical power and/or to generate steam from fluids circulating in steam tubes arranged inside the combustion chamber, and a flue gas, where the flue gas is withdrawn from the combustion chamber and is cooled to a temperature that results in condensation of the flue gas, or conversion of the flue gas to a supercritical fluid having a density of at least 600 kg/m^(3), and where the liquid or supercritical fluid formed, is safely deposited, and a plant for carrying out the method, are described.

A cable arrangement for feeding power and signals to downhole equipment, such as an electrically submersible pump (6), within an oil or gas well, comprising an upper suspension element (15), a lower connector (22), a docking station (11) for the downhole equipment coupled to said connector (22), and a cable (8a), comprising lines for power and signal. The cable extends between, and is coupled to, the upper suspension element (15) and the lower connector (22). The docking station (11) is adapted for attachment to the inner surface of a production tubing (5), that a narrow gap is formed between the production tubing (5) and the downhole equipment (6). The cable (8) is shaped to fit inside the gap by having a first dimension in the radial direction of the gap, which is smaller than the gap and a second dimension in the tangential direction of the gap, which is substantially larger than the first dimension.

Subsea power supply assembly (10, 20) supplying electric power to a motor (11) at a second location (90) from a first location (80), comprising a variable speed drive (13) (VSD) and a step-up transformer (15) connected to it. At a subsea location the assembly comprises a first step-down transformer (17) with input (17a) and output (17b) and an uninterruptable power supply (25) having an input (25a). A step-out cable (19) supplies power from the step-up transformer (15) to the motor (11). The cable (19) connects to the first step-down transformer (17). The speed of the electric motor (11) is proportional to the output frequency of the VSD (13). The power receiving input (25a) of the uninterruptable power supply (25) connects to the output (17b) of the first step-down transformer (17), thereby receiving electrical power with frequency equal to the output frequency of the VSD (13).

An oilfield tubular, such as a stinger (1), designed to be installed in a tubing hanger (2) in an XMT (Christmas tree) located on the sea bed, is presented. The oilfield tubular (1) is exposed to the production bore (4) pressure, and includes axial sealing means (6) located on an end (1a) of the tubular (1). The axial sealing means (6) includes a metal c-ring seal (6a), which metal c-ring seal (6a) is smaller in cross section than the thickness (t_(1)) of the oilfield tubular wall (1c). The opening (6b) of the metal c-ring seal (6a) is facing the high pressure side of the production bore (4). This pressure tend to expand the c-profile to firm engagement with contacting surfaces.

Subsea well assembly having a Xmas tree (107, 207) and wellhead (103). From a tubing hanger (113) a tubing extends into the well. A part of a production flow passage extends vertically from the tubing hanger (113) in a vertical bore (111) of the Xmas tree. A fail close production master valve (PMV) (117) is arranged in the production flow passage. The tubing hanger (113) is arranged below the Xmas tree (107), such as in the wellhead (103). The Xmas tree (107) exhibits a branch (115) that deviates from the vertical bore (111), which branch constitutes part of the production flow passage. The fail close type production master valve (PMV) (117) is arranged in the branch (115).
