This equipment includes the subsea control module (SCM) and its base, the subsea accumulator module, downhole interface unit, electrical and hydraulic connections, and various instrumentation.

The SCM is configured to suit your specific field requirements using field-proven designs built from a suite of standard components. The modular system approach enables customization to meet your project needs.

Reliable in design, OneSubsea SCMs provide subsea production fields with market-leading availability and a short response time.
