The main component of the tree mounted control system is the Subsea Control Module (SCM). The SCM contains electronics, instrumentation, and hydraulics for safe and efficient operation of subsea tree valves, chokes, and downhole valves. Other tree mounted equipment includes various sensors, electrical and hydraulic connectors.
Over 1,000 subsea wells are controlled using FMC’s tree mounted control systems with an uptime rate of 99 – 100% for most systems. The technology today controls wells at distances up to 120 km, and in water depths of 3,000 m/10,000 ft with 15k reservoir pressure rating.
FMC's standard SCMs are available in various sizes and functionality.
