Subsea Control & Accumulator Modules - Oil & Gas | OneSubsea

Manifold- and Tree-Mounted Controls

Customize from a suite of standard components to meet your project needs

Dual-contact vertical tree instrumentation EFS.

Our manifold- and tree-mounted controls equipment includes

  • subsea control module (SCM) and its base
  • subsea accumulator module
  • downhole interface unit
  • electrical and hydraulic connections
  • various instrumentation.

The modular SCM is configured to suit your specific field requirements using field-proven designs built from a suite of standard components. Our reliable SCMs provide subsea production fields with market-leading availability and a short response time.
