Electrohydraulic control and monitoring

The subsea control module (SCM) is the heart of the production control system. It provides electrohydraulic control and monitoring for a wide range of field equipment and functions, including tree valves and chokes, manifold valves, pressure and temperature monitoring, downhole intelligence control and monitoring, sand detection, corrosion monitoring, and multiphase flow measurements. We have delivered equipment for more than 650 subsea wells and more than 800 SCMs worldwide. Our SCM is qualified for water depths to 10,000 ft [3,000 m]. 

Compact version for additional flexibility

A compact, lighter version of the EH MUX subsea electrohydraulic multiplex system is available for multiple applications ranging from those requiring limited functionality to applications that require a dedicated data hub to handle communication from multiple instruments located on the seabed. This lighter version uses the field-proven components of the standard EH MUX system with a compact build that enables installation via lift line, diver, or both.
