Marine Well Containment Company (MWCC) is responsible for the maintenance, deployment and operation of the Containment System during a response to a deepwater well control incident in the U.S. Gulf of Mexico. MWCC utilizes the facilities and services of Technip USA and Core Industries to store, maintain and test the equipment in Mobile, Alabama. The selection of Mobile for its SURF shore base allowed MWCC to tap into the skilled and industry-experienced workforce of Alabama to achieve its mission to be continuously ready to respond to a deep-water well control incident in the U.S. Gulf of Mexico.
