A remote locking system for a blowout preventer (BOP) includes a locking mechanism configured to move to adjust the remote locking system between an unlocked configuration in which the remote locking system enables movement of a ram of the BOP and a locked configuration in which the remote locking system blocks movement of the ram of the BOP. The remote locking system also includes a gear assembly coupled to the locking mechanism, a motor coupled to the gear assembly, and an electronic controller configured to provide a control signal to activate the motor to drive the locking mechanism to move via the gear assembly.

A rotary lock system includes a gear configured to be driven to rotate via an engine. The rotary lock system includes a rotatable starter component configured to engage the gear via an interface. The interface includes a circumferential gap to enable the gear to rotate through an angle before contacting and driving the rotatable starter component.

Starter engine system for a rotary lock

A locking assembly includes a first motor gear configured to be rotated in a first direction. The locking assembly also includes a second motor gear configured to be rotated in a second direction. The locking assembly also includes a first lock gear configured to be rotated in the first direction in response to the first motor gear rotating in the first direction. The locking assembly also includes a second lock gear configured to be rotated in the second direction in response to the second motor gear rotating in the second direction. The locking assembly also includes a locking mechanism configured to be rotated in the first direction in response to the first lock gear rotating in the first direction, and to be rotated in the second direction in response to the second lock gear rotating in the second direction.
