Completion Workover Riser System

FMC’s Well Access Completion Workover Riser (CWOR) system is used for installation, completion and intervention of Subsea Trees. It can be configured for FMC’s Enhanced Horizontal and Vertical Subsea Tree systems in addition to legacy and other suppliers’ Subsea Tree equipment.

The system is designed and qualified in compliance with the industry’s highest standards, including ISO13628-7 and Safety Integrity Level 2 (SIL-2). FMC provide full system integration of the CWOR system with the subsea equipment and vessel to reduce complexity of interface management, and therefore minimize operational risk.

FMC’s CWOR system is available in pressure ranges from 5,000 psi to 15,000 psi and bore sizes from 5 1/8” to 7 1/16”.
The system complies with ISO13628-7, has the capability for Safety Integrity Level 2 (SIL-2) control of both emergency shutdown (ESD) and emergency quick disconnect (EQD), whilst delivering accelerated response times, and is configurable to suit anchored, Dynamically Positioned and Jack-up vessels.

With FMC’s CWOR system, operators can benefit from:

  • Minimal operational costs with less offshore personnel
  • Minimal third party equipment on the vessel
  • Minimal operational risk through system integration
  • Minimal operational risk through Safety Integrity Level 2 (SIL-2) rated fast response control system
  • Minimal risk and maximum operating envelope through use of optional Riser Monitoring and Management
