Open Water Lubricator Valve (OWLV)
Hydraulically operated Ram type BOP valve
Well isolation and cutting, well intervention Blow Out Preventer (BOP)
Pressure balanced BOP well isolation Ram valve designed for superior reliability & performance
- Open Water Lubricator Valve [OWLV]
The En-Tervene Open Water Lubricator Valve is single piston mounted on a vertical axis to the well bore and the predetermined piston to ram travel relationship provides maximum force in the cutting/close stroke. The En-Tervene is equipped with verification lines for guaranteed retraction and a secondary system activated in the event of losing hydraulic control makes it an innovative piece of engineering.
- Cutting capability from 0.108” slickline up to 2 7/8” coiled tubing with a 0.204’’ wall thickness 90 KSI coiled tubing c/w 7/16’’ logging cable
- Should surface hydraulic control be lost, the secondary system can be activated to retain both upper and lower valves in the open position.
- Chemical injection facility below the rams via a dual protected NRV.
- Open verification lines to verify piston has fully retracted to the open position.
- The valve provides protection against dropped objects to the upper surface of the ram bodies. Impacts up to 35KJ have no effect on the operational or sealing reliability.
- Bi-directional sealing
- The En-Tervene OWLV is a fully pressure balanced system enabling a Fail-as-is (FAI) operating mode.(Traditional BOP fails open)
- Actuation mechanism in the En-Tervene OWLV ram design comprises a single piston mounted on a vertical axis to the bore well. (Traditional BOP operated via dual horizontally opposed pistons)
- Significantly reduced external envelope
- Negates requirement of complex ram lock system
- Piston to ram travel relationship predetermined to provide maximum force in the cutting/close stroke area
