Subsea Intervention System

Subsea Intervention System

Invention
  • Magnum Technology for Maximum Reliability: WOM’s Subsea Intervention System (SIS) makes full use of Magnum gate valve technology, incorporating Hydraulic Fail-Close Gate Valves and Subsea Magnum Gate Valve in both the Emergency Disconnect Package and the Lower Rise Package

 

Unique Design
  • Engineered for Safety:  WOM’s SIS isolates wellbore pressure while tools are being changed out providing two levels of redundancy for increased safety. A pilot-operated directional control valve fed from an independent subsea accumulator bank ensures a reliable and rapid response to ESD commands from the surface

 

 Extraordinary Craftsmanship
  • Industry Certified: WOM’s SIS is certified to API 6A and ISO 10423 specifications and is PR2 and PSL3G rated

 

WOM’s Subsea Intervention Systems are available in both Riser and Riser-less configurations. WOM’s LIS design considers maintainability and ease of internal/external inspection and cleaning. Seals and gaskets are easily replaceable in field conditions, areas where sea water/produced fluids may become trapped are easily dismantled. The Lightweight Intervention System (Riser-less) provides operators with deep water intervention capabilities from a wider variety of vessels and at less than half the day rate cost of traditional intervention systems. Deploying the LIS from a vessel has become an effective alternative to intervene and repair subsea wells compared to utilizing conventional drilling rigs.

  • Magnum Gate Valve and actuator can cut up to 2-7/8” coil tubing to shut in the well without leaving a slug in the valve body
  • Emergency Disconnect Package is a monoblock construction measuring 7-3/8” and is capable of withstanding up to 10,000 PSI
    • Safety valve capable
    • 7-3/8” Magnum Hydraulic Fail-Close Gate Valve capable of cutting electric line and fully sealing up to 10,000 PSI
    • Pilot-operated quick-dump valve causes actuator to automatically close with loss of hydraulic pressure
  • Lower Riser Package is a monoblock construction measuring 13-5/8” and is capable of withstanding up to 10,000 PSI
    • 7-3/8” Subsea Magnum Gate Valve capable of cutting electric line and fully sealing up to 10,000 PSI
    • 7-3/8” Subsea Magnum Gate Valve with fail as-is actuator capable of cutting coil tubing or wireline up to 2-7/8” and fully sealing at 10,000 PSI
