Overview

The Cameron Omni-Choke provides the benefits and functionality of all-electric actuation to both greenfield and brownfield applications by virtually any traditional multiplexed controls system through a simple changeout of the choke. The SIIS compliant interface allows the Omni-Choke to be treated as a standard instrument, compatible with traditional subsea control modules. Functioning successfully since September 2008 in the K5F Field in the North Sea, the Omni-Choke makes all-electric performance a reality.

The Omni-Choke provides:

 

  • Electric actuation with field-proven subsea insert-retrievable choke
  • High operability, reliability, and availability
  • Smooth, accurate, precise operation and control with adjustable flow
  • Compatible, retrofittable, and remotely operable with any subsea production system
  • Detectable and measurable vibration-monitoring capability
  • Position feedback – Continuous, real-time position indication throughout the process
  • Superior response time – Less than five minutes from fully open to fully closed
  • Self-locking – fail as-is
  • Plug and play – standardized SIIS-compliant interface 
  • Condition-monitoring capabilities enabling preventive/proactive maintenance
