Tree-, Manifold-, and HIPPS-Mounted Controls

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

Dual-contact vertical tree instrumentation EFS.

Maximize uptime and exceed production targets

OneSubsea's reliable subsea control systems help you maximize uptime and exceed your production targets. Our tree-, manifold-, and HIPPS-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.
