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.

Aker Solutions | Date: 2015-05-11

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from fluids circulating in steam tubes arranged inside the combustion chamber, and a flue gas, where the flue gas is withdrawn from the combustion chamber and is cooled to a temperature that results in condensation of the flue gas, or conversion of the flue gas to a supercritical fluid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 clamp connector (1) is designed for subsea operations. It is disposed around two different hubs for engaging and disengaging the hubs. It comprises clamp segments (9), bracket members (6) and ring elements (2). Each clamp segment (9) is so supported and configured in the connector (1), such that it can rotate tangentially and transversally along the respective ring element (2) for engaging and disengaging the hubs.

A vertical subsea Xmas tree (200) having a production bore (203) and two valves (10) in the production bore (203). Each valve (10) has a valve gate (18, 20) which is functionally connected to an actuator (38, 40) moving the valve gate bidirectionally between an open position and a closed position. The production bore (203) is sealed off by the valves (10) in the closed position. The valve gate (18, 20) is provided with a string cutting edge (34).


The invention provides a multipurpose tool arrangement for riserless invention of a subsea well. The multipurpose tool (40) which is adapted to be connected at the lower end to a Christmas tree (50) which has a tubing hanger (52) and an annulus bore (60) being defined through said tubing hanger (52). Said tool (40) comprises a tubular element (48) and a Christmas tree connector (41), said multipurpose tool (40) is adapted to receive a second tool (64), which is operated by a cable (49), said second tool (64) in turn being adapted to install a plug (70) in said tubing hanger annulus bore (60), through said multipurpose tool (40), said arrangement also comprising a pressure control head (47) through which said cable (49) extend. The invention also provides a method for removal or installing of a Christmas tree.

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).

A method of sharing data in a subsea network comprising a plurality of nodes interconnected by a plurality of data connections arranged to carry data to and from equipment in subsea installations, the method comprising: storing data in a mass subsea data store provided across one or more nodes in the subsea network configured to act as a subsea data server; and on receiving, at the subsea data server, a request for access to data stored in the mass subsea data store, the subsea data server retrieving the requested data from the data store and causing the requested data to be sent over the subsea


Patent
Aker Solutions | Date: 2016-06-08

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.

A lifting device for lowering a pipeline end from a water surface to a seabed, alternatively later retrieval of the same from the seabed to the water surface, said pipeline end being provided with an outboard connecting part designed for mating and connection with an inboard connecting part on the seabed. The lifting device includes a hang off clamp adapted for connection with the outboard connecting part, at least one lifting arm pivotably connected to the hang off clamp at a respective first end of said at least one lifting arm and a yoke, said yoke being adapted to be releasable connected to the at least one lifting arm at a respective second end of said lifting arm, said at least one lifting arm having a locking arrangement for securing the at least one lifting arm to the hang off clamp in a non-rotational resting position. A method for lowering of a pipeline end from a water surface and retrieving a pipeline end from a seabed by use of the lifting device is also disclosed.


Patent
Aker Solutions | Date: 2016-09-28

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).
