  • Patent number: 10851805
    Abstract: An actuator assist apparatus for use with an actuator has a housing and a piston member slidably disposed in the housing. The piston member divides the interior of the housing into a first fluid chamber and a second fluid chamber. The actuator assist apparatus is configurable between a first, primed, configuration and an activated configuration. A force applicator is configured to store energy when the apparatus is in the primed configuration and release the energy to move the piston member relative to the housing. Movement of the piston member applies a force which assists in urging the actuator towards an extended configuration, thereby reducing the minimum operating pressure of the actuator.

  • Patent number: 9297235
    Abstract: A production control system for an underwater well, comprises: first electrically operated means for supplying first hydraulic fluid, for opening a first control valve of the well; second electrically operated means, for supplying second hydraulic fluid at a higher pressure than said first fluid, for opening a further control valve of the well; electronic circuitry (SEM1) for providing electrical power for operating said first and second means; and means for controlling the sequence of closing said control valves as a result of a loss of electrical power from said electronic circuitry. The controlling means comprises: electrical power storage means; detection means responsive to said loss of power from said electronic circuitry; and means coupled with said detection means for using electrical power from said storage means to keep said further control valve open for a period after closure of said first control valve and close it after said period.

  • Patent number: 6564872
    Abstract: Modern subsea wells utilise an electrohydraulic control system which switches hydraulic power to various control components in dependence on received control signals. The mounting and interconnection of the control components tends to be complicated. The invention provides a manifold comprising a first manifold body 6 having a number of openings and flow passageways therethrough. The manifold body is selectively configurable by selecting predetermined openings in order to achieve a desired configuration of flow passageways between control devices 1, 2, 13, 4. The manifold simplifies the interconnection of the hydraulic components and provides greater flexibility in the location of the components. The manifold body also provides a platform for mounting the control devices.
