Design of switch system of RMR lift pump group

Abstract:

In offshore oil production trees or subsea equipment pipeline systems， when it is necessary to perform switching operations such as opening and closing the pipelines， manual operation is not feasible in deep-sea environments. Therefore， work-class ROVs or underwater measurement and control systems are typically employed for remote control. This paper aims to achieve a multi-state working mode of the RMR lift pump group pipeline， establishing an underwater HPU system based on the principles， parameters， and structural design of underwater hydraulic systems. Selection of hydraulic control ball valves as the actuator， and a reliable testing scheme for ball valves adapted to the underwater working conditions of RMR is proposed. A design for a pipeline switching system suitable for the RMR lift pump group has been completed. This research has a wide range of application value for the RMR lift pump sets and other underwater equipment pipeline switching systems design.
