Abstract

A flexible deployment system is used to deploy subsea/downhole well equipment or modules from a multi-purpose vessel without requiring a moon pool and a derrick or tower. The deployment system may include the vessel and a deployment frame disposed on the vessel. The deployment frame includes a protruding section extending as a cantilever beyond an external edge of the vessel, and the protruding section includes an aperture formed therein to facilitate construction of the well equipment or modules through the protruding section. The deployment system also includes an actuation assembly coupled to the protruding section to selectively transition the protruding section to a collapsed, split, or retracted orientation out of a deployment path of the well equipment or modules. The system allows for controlled deployment of well equipment or modules including at least a string of downhole tools or tubulars coupled end to end from the side of the vessel in a single trip.

Abstract

A power triad of an umbilical may be rotated during multiple transition lengths to position each power cable of the power triad equally at radial orientation over the length of the umbilical. A first portion of the umbilical includes the triad in a first radial orientation, a second portion of the umbilical includes the triad in a second radial orientation, and a third portion of the umbilical includes the triad in a third radial orientation. The triad is rotated a first one hundred twenty degrees from the first radial orientation to the second radial orientation during a first transition length. The triad is rotated a second one hundred twenty degrees from the second radial orientation to the third radial orientation during a second transition length. The use of three radial orientations along the length of the umbilical may reduce imbalances between the power cables of the triad.

Abstract

A subsea connector that includes a connector capable of selectively connecting to a spool body to form a connector assembly. The subsea connector may include an adapter ring that is capable of connecting the spool body to the connector. The connector assembly may be lowered onto a wellhead member and locked into place by a movable piston and split lock ring. While the connector assembly is in the unlocked state, the adapter ring may be rotated moving the connector up or down with respect to the spool body, which lands on the wellhead member. The movement of the connector may be used to vary the alignment of the connector locking means with respect to the locking profile of the wellhead member. This change in position may be used to modify the preload force applied to the connector when locked onto the wellhead member.

Abstract

An internal tree cap having a running configuration and a latched configuration to be selectively secured to a tree spool. The tree cap may include an inner sleeve movable between upper and lower positions. The movement of the inner sleeve to the lower position may simultaneously engage a locking profile within the tree spool and energize a sealing element around the exterior of the tree cap. The tree cap may be a low profile tree cap that is flush with the top of the tree spool when installed. The tree cap may provide a collateral beneficial locking means to secure a tubing hanger within the tree spool. A lower housing may be attached to the tree cap to seal on the exterior of the upper neck of the tubing hanger. The tree cap may include a profile to accept a wireline plug.

Abstract

A locking tree cap for use on a subsea tree. The tree cap may be installed and retrieved using a remote operated vehicle. The tree cap may include deflectable collet fingers that lock the tree cap to a tree spool. The deflectable collet fingers may be adapted, such as with enlarged heads, to extend into recesses of the tree spool when the tree cap has been landed on the tree spool. The tree cap may be locked onto a tree spool before energizing sealing members within the bores of the subsea tree, thereby protecting the sealing members from damage during the installation of the tree cap onto the tree spool. The tree cap may include soft landing means such as a plastic cap, on the end of stabs to protect the sealing members as the tree cap is landed. The tree cap may include a secondary locking mechanism used to further secure the tree cap to the tree spool.

Abstract

A retrievable tree cap for use on a subsea tree having a concentric bore. The tree cap may be installed and retrieved using a remotely operated vehicle. Hydraulic pressure may be used to lock the tree cap onto the subsea tree and to set the tree cap seals. The tree cap is locked onto the subsea tree before setting the seals within the concentric bore. The tree cap includes a locking means that may engage a profile within the subsea tree regardless of the radial orientation of the tree cap. The tree cap may be used to hydraulically isolate an annulus bore from the production bore of the subsea tree. The tree cap may provide for the injection of a corrosion inhibitor within a cavity of the tree cap and may also provide for the removal of water trapped between the tree cap and the subsea tree.

Abstract

A coupling switches control fluid from a tubing hanger to a downhole completion of a subsea well. The coupling, located between a tubing hanging running tool and a downhole completion, includes a coupling body and a tubing hanger. A hydraulic poppet switches control fluid flow from a first and second flow path. The hydraulic poppet includes an isolation sleeve for opening and closing a first and second inlet port. At least two perimeter seals provide fluid isolation for the first flow path. A retainer seal seals the coupling body against the second inlet port. A retaining sleeve holds the coupling body against the tubing hanger. A first and second circumferential seal are located on opposite ends between the coupling body and tubing hanger. The hydraulic poppet is adapted to move perimeter seals and the retainer seal to open and close the first and second inlet ports.
