Marine Well Containment Company (MWCC) has announced the completion and delivery of its Expanded Containment System (ECS), bolstering well containment capabilities and response readiness for operators in the deepwater US Gulf of Mexico
The company’s three capping stacks include the Subsea Containment Assembly (SCA), 15k psi Capping Stack (single ram) and the 10k psi Capping Stack (dual ram)

The enhanced system builds on the equipment and technology put into place with MWCC’s Interim Containment System, made available in February 2011.

“The completion of the Expanded Containment System represents a major milestone for our company and a significant investment from industry,” said MWCC chief executive officer, Don Armijo. “Arrival of the full system underscores MWCC’s commitment to meet members’ needs and to provide industry-leading well containment equipment and services.”

The containment system, which consists of equipment from the company’s interim and expanded systems, was built for use in deepwater depths up to 10,000 feet. It 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. MWCC’s suite of containment equipment enables the company to mobilise and deploy well containment technology and equipment that can be adjusted to meet the unique requirements of a well control incident. The containment system includes two modular capture vessels (MCVs), three capping stacks, subsea umbilical, risers and flowlines (SURF) equipment, and additional ancillary equipment.

MWCC’s two shore base locations provide the storage, maintenance and skilled personnel necessary to support the deployment of MWCC’s containment system and are strategically located along the US Gulf Coast.

The company’s three capping stacks include the Subsea Containment Assembly (SCA), 15k psi Capping Stack (single ram) and the 10k psi Capping Stack (dual ram). These stacks vary in size and capabilities and will be utilised depending on specific incident factors.

MWCC’s SURF equipment is used to flow fluid from the capping stack to capture vessels on the surface. The company’s two MCVs, the Eagle Texas (MCV A) and the Eagle Louisiana (MCV B), are modified Aframax tankers outfitted with modular processing equipment designed to capture, process, store and offload liquids from a damaged well. Each MCV can process up to 50,000 barrels of liquid per day with 700,000 barrels of liquid storage capacity and can offload the liquids to shuttle tankers.
