  • Flow variation system
    Patent number: 10317014
    Abstract: Methods of remotely, selectively controlling the flow rate of fluid moving through a subsea pipeline during dewatering of the pipeline involve a control unit of a subsea valve actuation system selectively, autonomously varying the flow of fluid through a fluid flow conduit of the system fluidly coupled to the pipeline at the pig receiving end thereof based at least partially upon one or more signals emitted by at least one pressure transducer or flow meter fluidly coupled to the fluid flow conduit.

  • Facilitating the transition between flooding and hydrotesting with the use of an intelligent pig
    Patent number: 10215341
    Abstract: Methods of remotely facilitating the transition between flooding and hydrotesting a subsea pipeline include a control unit of a subsea valve actuation system closing off fluid flow out of the pipeline at the receiving end thereof based at least partially upon one or more signals emitted by at least one intelligent pig that has passed through the pipeline during flooding and without the involvement of an external source at the surface, or a UV, at the pig receiving end of the pipeline.

  • Pipeline hydrate inhibitor and method of reducing hydrates using the hydrate inhibitor
    Patent number: 10124375
    Abstract: Compositions and methods for reducing the formation of hydrates within subsea or over-land pipeline systems. The compositions and methods include the use of organic salt solutions, such as an acetate salt solution, to precondition, treat, and/or dewater the pipeline systems, or employ the use of the organic salt solutions during other pre-commissioning operations. An effective concentration of an organic salt solution acts to reduce hydrates and/or inhibit hydrate formation within the pipeline systems.

  • SUBSEA TRANSITION SYSTEM
    Publication number: 20180045598
    Abstract: Methods of remotely facilitating the transition between hydrotesting and dewatering of a subsea pipeline include a control unit of a subsea valve actuation system determining when hydrotesting of the pipeline has been completed and autonomously allowing fluid flow out of the pipeline at the receiving end thereof without the involvement of an external source at the surface, or a UV, at the pig receiving end of the pipeline to allow dewatering the pipeline from the launch end of the pipeline.
