LOCKING SYSTEM FOR A BLOWOUT PREVENTER FUNCTION

摘要

A hydraulic locking system for a blowout preventer function is provide. The locking system enables implementation and practical engagement as part of the routine functioning of the blowout preventer. The locking system may be adapted to fluidly interconnect a control system port and a function port so as to trap and release hydraulic actuation pressure against the function port and any blowout preventer function fluidly communicating thereto.

主权项

1. A system for locking actuation pressure in a BOP function, comprising:
a control system configured to control a hydraulic pressure therein; a control line fluidly communicating the BOP function to the control system; and a hydraulic locking apparatus disposed along the control line, wherein the hydraulic locking apparatus comprises:
a function port adapted to fluidly communicate to a portion of the control line connected to the BOP function;a control system port adapted to fluidly communicate to a portion of the control line connected to the control system; anda locking mechanism movable from an unlocked configuration to a locked configuration, locking the actuation pressure against the function port.
