Autonomous Shutdown Valves (ASV)

Overview

Autonomous Shutdown Valves (ASV) are designed to operate subsea PLEM valves used in CALM Buoy and similar tanker loading/unloading subsea pipeline systems. Comprising of a subsea hydraulic valve actuator and control system, the ASV can operate subsea pipeline ball valves on demand or automatically based on pipeline pressure changes. The ASV also provides fully automatic and reliable fail-safe valve automation of subsea PLEM valves to isolate subsea pipelines from flexible risers in all weather conditions.


Applications

Valve automation of subsea PLEM valves used in subsea pipeline loading systems, CALM Buoy pipeline systems and similar systems.


Operating Ranges

  • Water depths down to 200m
