  • Patent number: 10415329
    Abstract: A technique facilitates landing of a subsea component, e.g. a tubing hanger, by utilizing a poppet valve to provide an indication of proper landing. The poppet valve is combined with the tubing hanger or other subsea component and oriented to engage a corresponding landing surface. A pressure line is routed to the poppet valve, and the poppet valve is biased to an open flow position with respect to the pressure line during deployment. If the subsea component is properly landed, the corresponding landing surface is able to shift the poppet valve to a closed position. The closed position may be verified via pressure testing through the pressure line.
    Type: Grant

  • Patent number: 9534466
    Abstract: A cap system for subsea equipment that can be employed on various subsea equipment including but not limited to a vertical monobore tree, a horizontal tree, a wellhead and a tubing head spool. The cap system includes a cap assembly that has the flexibility of installation and retrieval for open water as well as a through a riser with a running tool. The cap assembly also does not require any orientation during installation. The cap system includes a debris cap assembly installable in engagement with the cap assembly. The debris cap assembly interfacing with the cap assembly provides the ability to inject and bleed fluids through a main bore and an annulus bore of the subsea tree independently and without removal of the debris cap assembly and cap assembly.
