AI Technical Summary
Technical Problem
Hydraulic fluid leakage and excessive use in hydraulic motors of blowout preventers (BOPs) due to parallel arrangements, leading to inefficiency and increased fluid requirements.
Method used
A series arrangement of hydraulic motors coupled via a connector conduit, allowing shared fluid flow for multiple motors, reducing fluid usage by sequential operation.
Benefits of technology
Substantially reduces hydraulic fluid consumption by up to 50-90% compared to parallel arrangements, minimizing leakage and hardware requirements.

Abstract
A system includes a blowout preventer (BOP) having a ram assembly having first and second pistons. The first piston is configured to drive a first ram into a cavity of the BOP and the second piston is configured to drive a second ram into the cavity. The system also includes a motor assembly having first and second motors. The first motor is configured to cause an extension of a first lock to constrain the first piston and the second motor is configured to cause an extension of a second lock to constrain the second piston. The first and second motors are fluidly coupled to each other in a series arrangement via a connector conduit. The connector conduit is configured to flow a motor fluid sequentially through the first and second motors.
