MWCC’s Containment System can cap or cap and flow a deepwater well control incident at water depths up to 10,000 feet. The system includes two Modular Capture Vessels (MCVs), which can each capture up to 50,000 barrels of liquid per day, three capping stacks, enhanced subsea equipment and additional ancillary equipment.
In 2012, MWCC worked closely with the Department of the Interior (DOI) and BSEE to complete a demonstration of its Interim Containment System (ICS) in the deepwater U.S. Gulf of Mexico. The demonstration included a physical deployment of the 15k psi Capping Stack (single ram) and validated that MWCC has a system in place that is ready to respond.
In 2014, MWCC conducted extensive testing of its Containment System, including two System Integration Tests (SIT) with the Eagle Texas and Eagle Louisiana to verify overall system functionality of the vessels and topside processing equipment. The SITs effectively validated the ability of the vessels, topside processing equipment and response personnel to safely and effectively respond to a well control incident. In addition, MWCC successfully conducted two-week sea trials with each of the MCVs, in coordination with the U.S. Coast Guard, to test the speed, maneuverability, equipment and safety features of the vessels.
MWCC maintains a constant state of readiness with thorough training of its workforce and response personnel, and a robust maintenance and storage process for its equipment.
Before equipment from MWCC’s Containment System can be deployed, the Responsible Party must conduct an initial site assessment to determine a safe working environment for response operations and personnel. Part of the site assessment includes the removal (if possible) of debris that may hinder the safe installation of response equipment.
MWCC and the RP work closely to determine specific equipment and configuration needed at the well incident site.
At this time, the company is committed to being continuously ready to respond within its current operational geography and does not have plans to expand its scope beyond the U.S. Gulf of Mexico. Should that change, MWCC will work with the appropriate parties and its membership to effectively and safely expand its operations while still maintaining its readiness to respond to an incident.
In addition, MWCC works with WoodGroup PSN to maintain a Reservist Response Team comprised of experienced and trained personnel to operate the Containment System in the event of an incident. At all times, the Reservist Response Team is on-call and ready to be deployed and receives regular, comprehensive preparedness training consisting of classroom and hands-on equipment familiarization as well as scenario-based operation and emergency exercises at the MCV Shore Base.
MWCC’s Containment System combines equipment from the ICS and ECS, including enhanced Subsea Umbilical, Risers and Flowlines (SURF) equipment; two Modular Capture Vessels (MCVs); and three capping stacks – the Subsea Containment Assembly (SCA), 15k psi Capping Stack and the 10k psi Capping Stack. The system is able to cap and flow wells in up to 10,000 feet – as compared to 8,000 feet previously – and is able to contain up to 100,000 barrels of liquid per day.
