Deepwater Horizon accident and response

The Discoverer Enterprise arrives to install the capping equipment - July 2010

BP, government agencies and others worked together to control the spill and minimize its impact on the environment, human health, and the economy.

At its peak in 2010, the response effort involved the mobilization of approximately 48,000 people, the coordination of approximately 6,500 vessels and the deployment of approximately 2,500 miles (13.5 million feet) of boom to contain or absorb the oil. BP spent $14 billion and workers devoted more than 70 million personnel hours on response and clean-up activities. The Coast Guard ended the last remaining active cleanup operations in April 2014 and transitioned these areas to the National Response Center reporting process. The operational phase of the response ended in February 2015.

Immediately after the accident, BP also committed $500 million over 10 years to support independent research through the Gulf of Mexico Research Initiative (GoMRI).
