摘要： Subsea power supply assembly supplying electric power to a motor at a second location from a first location. The subseas power supply assembly includes a variable speed drive (VSD) and a step-up transformer connected to it. At a subsea location the assembly includes a first step-down transformer with input and output and an uninterruptible power supply having an input. A step-out cable supplies power from the step-up transformer to the motor. The cable connects to the first step-down transformer. The speed of the electric motor is proportional to the output frequency of the VSD. The power receiving input of the uninterruptible power supply connects to the output of the first stepdown transformer, thereby receiving electrical power with frequency equal to the output frequency of the VSD.

摘要： A handling device (1) for an installable and retrievable subsea apparatus (2) to engage a docking device (3) on a subsea installation, the docking device (3) having a pair of engagement members (4, 5). The device (1) is provided with a top member (6) and a pair of engagement arms (7, 8) depending therefrom to extend along the outside of the apparatus (2). Each of the arms (7, 8) at a free end thereof is provided with a hook (7′, 8′) configured to engage in releasable way the engagement members (4; 5). A rotatable handle (9) is located above the top member (6) and has an integral or linked stem (10) which extends through the top member (6) and is pivotally linked to a top region of the apparatus (2).

摘要： A subsea or downhole pump includes an inlet and an outlet. A flow of a multiphase fluid entering the inlet can have a variation in a gas volume fraction (GVF). The subsea or downhole pump includes or is operatively coupled to control devices which provide for a control as the GVF varies. The control devices include a first transmitter for an electric pump current, a second transmitter for at least one of a pump speed, a pump frequency, and a pump voltage, and a controller. The controller reduces a speed of the subsea or downhole pump when a measured pump current decreases, and increases the speed of the subsea or downhole pump when the measured pump current increases.

摘要： A well tube configured for use with a subsea well assembly which includes a Christmas tree arranged on top of a subterranean well. The well tube includes a bore, a lockable insert arranged within the bore, and a locking assembly. The locking assembly includes a locking dog which moves into and out of a locking position, an actuator which moves the locking dog, and a control channel which couples the actuator to an exterior of the well tube and controls the actuator to move the locking dog to removably lock the lockable insert within the bore

摘要： The invention relates to agate valve hydraulic actuator, said actuator comprising a cup shaped sleeve (9) which is operably coupled to an opening or closing element (5) of the gate valve (2), the actuator further comprising a movable primary piston (13) arranged within a primary cylinder (12) arranged at the inside of the cup-shaped sleeve (9), said primary piston (13) being con figured to move the sleeve (9) and hence said opening and closing element (5) towards an open or closed position of the gate valve (2) by a force applied to the primary piston (13). The hydraulic actuator is distinctive in that it further comprising a movable secondary piston (11) arranged within a secondary cylinder (10) arranged at the inside of the cup shaped sleeve (9), said secondary piston (11) being configured to move the sleeve (9) to the same position of the gate valve (2) as the primary piston by a force applied to the secondary piston in case of failure of the primary piston (13), said primary piston (13) and secondary piston (11) are independently operable of each other.

摘要： A weak link arrangement (1) designed for location on an umbilical (6, 7) extending on the seabed between respective structures potentially subjected to environmental hazards, like being snapped by an iceberg, which umbilical includes communicating fluid pipes and electric cables, is described. The weak link arrangement (1) includes a seabed frame (2) supporting an umbilical having a weak link multiconnecting structure (3) (UTA) installed in line, which weak link multiconnecting structure (3) (UTA) ensures continuous communication through the fluid pipes and electric cables until emergency disconnection takes place. Such disconnection is initiated by accidental pull in the umbilical, which pull activates disconnecting means and cable severing means.

摘要： A riser top connector assembly (20) is shown. The assembly (20) includes a first connector part (21) arranged on a flexible jumper prepared for connection with a second connector part (40) arranged on top of a marine riser tower assembly projecting from the seabed. The first connector part (21) is provided with suspension means adapted to engage with supporting means in order to be supported and be able to tilt in the marine riser tower assembly. The first connector part (21) includes a housing (22) that receives an extendable termination hub (23) having a clamp connector (24) attached thereto. The jumper termination hub (23) is alignable with a riser hub (44) on the second connector part (40) when the first connector part (21) is being tilted relative to the marine riser tower assembly.

摘要： 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/m3, and where the liquid or supercritical fluid formed, is safely deposited, and a plant for carrying out the method, are described.
