Marine Well Containment Company (MWCC, USA) has announced that its single ram capping stack, which is part of the company’s interim containment system, can now cap a well containing fluids with temperatures up to 177°C (350°F). Increasing the rating to that temperature required upgrading multiple pieces of equipment to ensure higher temperatures could be tolerated while still maintaining safe operation of the capping stack.

MWCC has received technical input from its member companies and industry providers throughout the rerate process and worked closely with regulators to ensure all requirements were met. The capping stack is now approved for use in these new applications and is part of MWCC’s long-term service offering to members and to non-members on a per well basis.

The most recent single ram capping stack is the centrepiece of the company’s interim containment system and weighs 100 tons. MWCC is the only well containment provider that has this industry-first capping stack capable of handling temperatures of 177°C (350°F) at pressures up to 15k psi. This summer, MWCC made available a more compact dual ram 10k psi capping stack designed to reach deepwater areas where well casings and riser systems are closely spaced.
