Problems solved by technology

Also, the length of the outboard flow line from the flow block increases the total area from which a leak can form; therefore, the longer outboard flow line from the flow block increases the potential for leaks to occur
The length of the outboard flow line of the self-flowing module can also lead to increased production costs
This is due to the increased amount of material required to construct the pipeline, and due to the increased labor cost of constructing the long outboard flowline from the flow module

Abstract

A subsea wellhead assembly positions a flow module between an outboard flowline of a subsea tree and a tubing hanger spool flowline. The subsea production assembly includes a wellhead, a tubing hanger spool disposed on the wellhead, and a subsea tree disposed on the tubing hanger spool. Production fluid may flow from the wellhead through the tubing hanger spool, and then through the tree. A tubing hanger spool frame mounts to and extends laterally from the tubing hanger spool and supports a downstream flowline having an upward facing hub. A tree frame mounts to and extends laterally from the subsea tree and supports an upstream flowline having an upward facing hub. A flow module having downward facing flowlines that couple to the hubs so that the weight of the flow module is distributed between the frames of the tubing hanger spool and the subsea tree.

Description

technical field [0001] The present invention relates generally to subsea production equipment and, in particular, to an improved flow module arrangement between a subsea production tree and a tubing hanger spool. Background technique [0002] A conventional subsea wellhead assembly includes a wellhead housing that supports one or more casing hangers at the upper end of a string of casing that extends into the well. A tubing hanger spool or "THS" is placed on the wellhead assembly. A production tree or "tree" is placed on the THS to control the production of well fluids. The tree typically carries chokes and valves to control well fluid flow and sensors to monitor well fluid flow. [0003] The subsea production tree will control the flow of hydrocarbons out of the wellhead and direct the hydrocarbons to associated equipment such as manifolds, flowlines, etc. for further operations. A subsea tree may have a flow module, such as a choke bridge module, fabricated as an integr...
