Abstract
A technique facilitates formation of subsea connections. A free portion of a stab plate connection system is moved into proximity with a fixed portion of the stab plate connection system at a subsea location. The free portion is initially engaged with the fixed portion via a docking probe. Subsequently, a local actuator is used to draw the free portion into an operating engagement with the fixed portion in which line couplers of the fixed portion are engaged with corresponding line couplers of the free portion.
Claims17
A method of forming a subsea lead connection, comprising:
- moving a free portion of a stab plate connection system into proximity with a fixed portion of the stab plate connection system at a subsea location;
- engaging the free portion and the fixed portion via a docking probe;
- operating an actuator on the fixed portion to draw the free portion into an operating engagement in which line couplers of the fixed portion are engaged with corresponding line couplers of the free portion;
- and
- further comprising selectively disconnecting and separating the free portion from the fixed portion via an ejection mechanism.
2 more elements
A method, comprising:
- employing an ROV to move a free portion of a stab plate connection system onto a docking probe of a fixed portion positioned at a subsea location;
- releasing the ROV from the free portion;
- after releasing the ROV, drawing the free portion into further engagement with the fixed portion;
- and setting a disconnect eject mechanism of the stab plate connection system;
- and
- further comprising selectively disconnecting and separating the free portion from the fixed portion and subsequently fully engaging the free portion and the fixed portion without recovery of the free portion to a surface location.
3 more elements
A system, comprising:
- a fixed portion of a stab plate connection system, the fixed portion having a plurality of line couplers;
- and
- a free portion of the stab plate connection system, the free portion having a plurality of corresponding line couplers and an ROV handle to enable delivery to the fixed plate via an ROV;
- wherein an engagement mechanism of the fixed portion is oriented to enable preliminary engagement of the free portion with the fixed portion upon delivery via the ROV;
- and
- wherein a local actuator is permanently coupled to the stab plate connection system to move the free portion and to draw the plurality of corresponding line couplers into engagement with the plurality of line couplers and further comprising a disconnect ejection mechanism to selectively disconnect and separate the free portion from the fixed portion without causing damage requiring recovery to a surface location.
