Containment System Overview

Marine Well Containment Company’s (MWCC) Containment System provides operators in the deepwater U.S. Gulf of Mexico the well containment technology and equipment necessary to mount an effective response to a subsea well control incident.

The company’s Containment System includes two Modular Capture Vessels (MCVs), enhanced Subsea Umbilical, Risers and Flowlines (SURF) equipment, three capping stacks and additional ancillary equipment. In designing the system, MWCC worked with regulators from the Bureau of Safety and Environmental Enforcement (BSEE) and the U.S. Coast Guard to ensure all expectations were met and that the system would not only safeguard the U.S. Gulf of Mexico but continue to allow new permits to be issued.

The MWCC Containment System is built for use in the deepwater U.S. Gulf of Mexico in water depths from 500 feet to 10,000 feet, temperatures up to 350 degrees Fahrenheit and pressures up to 15k psi. MWCC’s suite of containment equipment enables the company to mobilize and deploy the most appropriate well containment technology based on the unique well control incident and equipment requirements. The system has the capacity to contain up to 100,000 barrels of liquid per day and handle up to 200 million standard cubic feet of gas per day.

The Containment System combines equipment from the company’s previous Interim Containment System (ICS) and the Expanded Containment System (ECS). MWCC’s Containment System is available for use by members as well as non-members on a per well basis. In keeping with the company’s mission to be continuously read to respond, the equipment is regularly tested and maintained to ensure a ready state at MWCC’s two shore bases.

The company is committed to advancing its technology to meet members’ needs and will continue to make upgrades and enhancements to its Containment System as necessary.
