Abstract: A wellhead assembly includes a tubular housing assembly having a housing sidewall, an axial bore, and a housing annulus passage extending from the axial bore through the housing sidewall. A tubing hanger is secured to a string of tubing and is selectively landed in the housing assembly. The tubing hanger has a vertical bore in fluid communication with the axial bore. A vertical tree assembly is selectively landed on the housing assembly, the vertical tree assembly having a tree member located axially above the tubing hanger. The tree member has a lateral bore for directing a flow of production fluid from a well. A tree annulus passage extends through a sidewall of the tree member. An external annulus passage extends external of the tree member and the housing assembly and is in fluid communication with the housing annulus passage and the tree annulus passage.

Abstract: Systems and methods for managing umbilical lines and one or more jumpers are provided. An example of a system includes a deployment platform carrying a winch and spool assembly, a tether management assembly, and an integrated electrical and/or hydraulic umbilical line extending between a spool on the winch and spool assembly and the tether management assembly. The winch and spool assembly is configured to deploy and to support the umbilical line. The tether management assembly includes a winch and spool assembly for deploying a flying lead and/or annulus jumper adapted to connect to an emergency disconnect package of a well control package for a well. A set of buoyant modules are connected to or integral with a portion of the umbilical line to be used to form an artificial heave compensation loop.

Abstract: A dog-style connector with a fail-safe mechanism for a marine riser system that connects a box portion and a pin portion of a riser. An actuator housing is affixed to an external surface of the box portion. The actuator housing has an outer bore and a threaded inner bore. An actuator body is threadably received in the inner bore. The actuator body has a hex head on its first end. The actuator body has a threaded fastener bore extending from the first end for receiving a threaded fastener. The actuator body has a second end that has a stem receptacle formed therein. The fastener bore is in communication with the stem receptacle. An actuator head, which includes a flange and a stem, is provided wherein the stem is positioned within the stem receptacle for sliding engagement therewith. Threads formed on the threaded fastener engage a threaded fastener receptacle formed in the stem of the actuator head.
