Marine Well Containment Company’s (MWCC) Containment System is comprised of industry-leading technologies and equipment, state-of-the-art maintenance and storage facilities and a highly experienced and capable workforce and response team.

Shore Base Locations
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 Gulf Coast.

  • The SURF Shore Base is located in Theodore, Alabama, near Mobile, where MWCC houses Subsea Umbilical, Risers and Flowlines (SURF) equipment, which is used to flow fluid from the capping stack to the Modular Capture Vessels (MCVs) as well as to provide dispersant and hydrate mitigation injection. The SURF Shore Base features 13 acres of equipment lay-down area, an 80,000 square-foot warehouse and one acre of easily accessible dockside space for heavy lift storage.
  • The MCV Shore Base in Ingleside, Texas, near Corpus Christi, is where MWCC houses, maintains and tests processing equipment for its two MCVs as well as its capping stacks. If needed in a response, up to two Aframax class tankers arrive to the shore base to be outfitted into MCVs with processing equipment that can separate sand and process liquids and gases flowed from the damaged subsea well. The shore base covers 12 acres and includes a 40,000 square-foot warehouse and equipment lay-down area necessary for the regular maintenance and storage of MWCC’s equipment.

Modular Capture Vessels
MWCC’s Containment System includes two MCVs – the Eagle Texas (MCV A) and Eagle Louisiana (MCV B). The MCVs are modified Aframax class tankers outfitted with modular topside processing equipment designed to capture, process, store and offload liquids from a damaged subsea well in a cap and flow scenario. The equipment has been assembled into large modules to facilitate more efficient transportation, lifting and installation from the shore base dockside onto the MCVs.

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. When not needed by MWCC, the vessels are operated by AET, Inc. for lightering service. Once called upon by the Responsible Party (RP) in a response, the vessels will mobilize to the MCV Shore Base within five to eight days to be outfitted into MCVs.

Capping Stacks
The capping stack, the centerpiece of the MWCC Containment System, is uniquely designed to cap or cap and flow a well in the U.S. Gulf of Mexico by creating a seal to shut off the flow of fluid from the well or by providing a conduit to safely flow well fluids to the two MCVs.

MWCC’s three capping stacks, which vary in dimensions, response capabilities and containment scenario, provide MWCC the ability to utilize the best capping stack based on the incident well’s specific parameters and condition.

SURF and Other Subsea Components
MWCC’s SURF equipment is used to flow fluid from the capping stack to the MCVs as well as to provide dispersants and hydrate mitigation injection.

MWCC’s subsea equipment includes flowlines, risers, Umbilical, Subsea Dispersant Injection System (SDIS), Hydrate Inhibition System (HIS), Subsea Autonomous Dispersant Injection (SADI) system, Riser Insertion Tube Tools (RITTs), Polished Bore Receptacle (PBR), Free Standing Risers (FSRs), Umbilical Termination Assembly (UTA), Light Duty Intervention System (LDIS), top hats, manifolds and additional ancillary equipment.

Reservist Response Team
MWCC and Wood Group PSN have established a Reservist Response Team made up of nearly 100 highly skilled and industry-experienced personnel, primarily based along the Gulf Coast.

In the event of a cap and flow scenario, the team will be deployed to maintain and operate the system – from the subsea equipment, including the capping stack, to the topside processing equipment onboard the MCVs. At all times, the Reservist Response Team is on call and ready to be deployed.
