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.

An installation tool arrangement enables installation of a flexible elongated element, such as a conductor, cable, tube or tube bundle, into a pipeline and to extend the flexible elongated element from the surface of the sea to the seabed by the use of a per se known pipeline pigging technique. The tool arrangement includes a first pipe junction tool at the pipeline entrance end for the flexible elongated element, and a second pipe junction tool at the pipeline exit end for the flexible elongated element. The installation tool arrangement includes a leading pig connected to the flexible elongated element to have it advanced through the pipeline toward the seabed by advancing said pig by means of the fluid flowing in the pipeline.

A semi-submersible floating structure for the drilling and production of offshore oil and gas is provided. The semi-submersible floating structure includes a pontoon having a plurality of pontoon sections, an outer edge, and an inner edge, the pontoon sections defining an interior space. The semi-submersible floating structure further includes a plurality of columns extending vertically upward from the pontoon. Each column has an upper section having an upper column width; and a lower section. The lower section has a bottom end coupled to the pontoon and aligned with the outer edge of the pontoon, the bottom end having a lower column width greater than the upper column width, at least part of the bottom end protruding into the interior space. The lower section further has a flared portion between the upper section and the bottom end; the flared portion having a width that varies from the upper column width at the upper section to the lower column width at the bottom end. A pontoon center-to-center distance between central axes of opposing sections of the pontoon is greater than a corresponding column center-to-center distance between central axes of opposing upper sections of the columns coupled to the opposing sections of the pontoon.

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.

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.

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).
