ABERDEEN, UK — Interventek will supply qualified 20,000-psi open-water well intervention shear and seal valves to Trendsetter Engineering in Houston.
The agreement gives Trendsetter exclusive global rights to deploy the 20K, 5-1/8-inch open-water valves over the next five years, with the first set to be delivered later this year.
The 20K Revolution valves will provide the well control function in the company’s new 20K Trident subsea intervention system, which is due to start operations on a forthcoming HP/HT subsea completion and intervention campaign in the Gulf of Mexico.
Interventek previously supplied Trendsetter with various 15,000-psi Open-Water Revolution valves, for use in multiple campaigns involving the 15K Trident intervention systems.
Tony Kitchener, sales and marketing director at Interventek, said the 20K Revolution series was qualified to rigorous API-17G and API 17TR8 standards.
Mike Cargol, vice president of services at Trendsetter, added, “This technology is the key to achieving a reliable HP/HT solution with around a 60% size and weight saving compared to other offerings. The result is a robust system, which can be reconfigured to support hydraulic, riserless or open-water risered interventions and mobilized quickly on a broad range of vessels with minimal modifications.
“The bottom line for the operator is enhanced safety, rapid response, increased operational efficiency and reduced cost.”
According to Interventek, subsea HP/HT interventions would normally employ hydraulic gate valves or rams for well control, but these are said to be slower to operate, larger and heavier.
The company’s shear and seal mechanism employs internal components and rotary actuators to shear through a range of wireline or coil tubing conveyance systems and seal the wellbore in a single operation, allowing for size and weight reduction of the assembly.
