In response to the Deepwater Horizon oil spill of 2010 , ExxonMobil , Chevron Corporation , ConocoPhillips and Shell Oil committed to providing a new containment response capability . These founding companies of MWCC recognized the need to be better prepared in the event of a deepwater well control incident . As a result of unprecedented industry collaboration , MWCC introduced the Interim Containment System in February 2011 , improving previous response capabilities and helping the industry get back to work in the U.S. Gulf of Mexico . In January 2015 , MWCC accepted its Expanded Containment System forming the MWCC Containment System which builds upon the past system capabilities
