Interventek Subsea Engineering has secured recent orders in excess of GBP 1M for their Revolution in-riser shear and seal safety valve.
The orders represent repeat business, from Louisiana based Professional Rental Tools LLC (PRT Offshore) to support well completion and intervention operations in the Gulf of Mexico. Interventek will supply its 6.375” 15,000psi working pressure valves to be included in PRT Offshore’s Subsea Safety System.
The PRT Offshore Subsea Safety System interfaces with the rig BOPs, subsea tree vendor tubing hanger running tool (THRT) and downhole functions during installation, workover or removal of subsea completions. The system is designed for deep water and high working pressure applications. The addition of the Revolution valve enables the operator to cut wire or coiled tubing introduced into the well and provides a seal from below after the cut. The valve also offers pump through capability to facilitate well kill operations.
Interventek’s Revolution valve can quickly and reliably cut all types of intervention media whilst protecting the integrity of its seal. Unlike other shear and seal devices, the technology uses separate cutting and sealing components so that the seal is not compromised. Resilient seals avoid the use of elastomer components for fluid containment, enabling use in HPHT and large bore applications. This simple, reliable design with many other features can be scaled to meet all wellbore sizes and operating pressures including 20,000 psi and is designed to meet API 17G requirements.
