Marine Well Containment Company upgrades capping stack temperature rating
HOUSTON -- Marine Well Containment Company (MWCC) announced that the single ram capping stack, which is part of the company’s interim containment system, can now cap a well that has fluids with temperatures up to 350° F. MWCC is the only well containment provider that has this industry-first capping stack capable of handling temperatures of 350° F, at pressures up to 15,000 psi.
The single ram capping stack is the centerpiece of the company’s interim containment system and weighs 100 t. Increasing the rating to 350° F required upgrading multiple pieces of equipment, to ensure higher temperatures could be tolerated, while still maintaining safe operation of the capping stack. MWCC 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 re-rated capping stack is the most recent containment system enhancement. This summer, MWCC made available a more compact dual ram 10,000-psi capping stack designed to reach deepwater areas where well casings and riser systems are closely spaced.
