  • 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.

  • Publication number: 20140116716
    Abstract: A spool module for a subsea well production tree and system is presented. The spool module is similar to traditional process modules, except that the spool module includes all its components and their conduits inside one body (or block). This module includes retrievable components used for production and annulus flow lines into one package. The spool module includes the production choke, annulus choke, and conduit bores integral in the block. The spool module includes all of these elements machined into one body having no additional conduits or piping outside of the body. The spool module may also be used in connection with a subsea tree during production of a well, or with several wells on a template or as part of a manifold.
