Single Line Stab And Coupler And Method Of Use

摘要

A single line stab uses internal threading that allows a remotely operated vehicle (ROV) to mechanically mate up the stab and receptacle without the use of additional tooling. The use of a single coupler allows for a compact stab instead of the large junction plates that are currently used. Can be used to hydraulically control valves, inject fluid, or to sample fluids sub sea.

主权项

1. A single line stab coupler, comprising:
a. a receptacle, comprising:
i. a receptacle housing comprising:
1. a receiving end and a mating slot through a predetermined portion of the receptacle housing, the mating slot defining a key receiver; and2. a connector end disposed opposite the receiving end;ii. a back plate disposed proximate the connector end; and iii. a hydraulic coupler disposed proximate the connector end and received at least partially into the back plate, the hydraulic coupler configured to operatively interface with a predetermined piece of subsea equipment; and b. a stab, comprising: i. a stab housing defining an interior void at least partially therethrough, the stab housing comprising a stab end configured to be cooperatively received into the receptacle and a handle end;
ii. an alignment key disposed about a predetermined portion of the stab housing, the alignment key configured to be cooperatively received into the mating slot when the stab is inserted a predetermined distance into the receptacle and align the stab into the receptacle;iii. a grab sleeve collet disposed within the interior void proximate the stab end;iv. a sleeve guide disposed within the interior void intermediate the stab end and the handle end;v. a locking rod slidingly disposed within the interior void and extending through the grab sleeve collet and the sleeve guide; andvi. a spring disposed about the locking rod intermediate the handle end and the sleeve guide.
