Abstract

A lock sequencing system includes a first fluid line that couples a fluid source to a first portion of a piston cavity of a blowout preventer and to a hydraulic motor of a lock. A first discharge valve is positioned along the first fluid line to delay delivery of fluid to the hydraulic motor of the lock to cause sequential closure of a ram coupled to the piston and locking of a locking member of the lock. A second fluid line couples the fluid source to a second portion of the piston cavity of the blowout preventer and to the hydraulic motor of the lock. A second discharge valve is positioned along the second fluid line to delay delivery of fluid to the second portion of the piston cavity to cause sequential opening of the ram coupled to the piston and unlocking of the locking member of the lock.
