NEW ORLEANS — The Bureau of Ocean Energy Management, Regulation and Enforcement
(BOEMRE)/U.S. Coast Guard Joint Investigation Team (JIT) today released its final investigative
report on the April 20, 2010, Deepwater Horizon explosion, loss of life, and resulting oil spill.

 
The report is comprised of Volume I, covering the areas of investigation under the jurisdiction of the
Coast Guard; Volume II, covering the areas of the investigation under BOEMRE jurisdiction; and a
supplement to Volume I – the Final Action Memo from Coast Guard Commandant Adm. Bob Papp.

 
The JIT was formed on April 27, 2010, by a convening order of the Departments of the Interior and
Homeland Security to investigate the causes of the Deepwater Horizon explosion, loss of life, and
resulting oil spill, and to make recommendations for safe operations of future oil and gas activities on
the U.S. Outer Continental Shelf (OCS). The JIT held seven sessions of public hearings, received
testimony from more than 80 witnesses and experts, and reviewed a large number of documents and
exhibits pertaining to all aspects of the investigation.

 
Volume I, released April 22, 2011, includes findings on five aspects of the disaster under Coast
Guard jurisdiction – including the explosions on the Mobile Offshore Drilling Unit (MODU) Deepwater
Horizon; the resulting fire; evacuations; the flooding and sinking of the Deepwater Horizon; and the
safety systems of the MODU and its owner, Transocean. The Coast Guard's Final Action Memo
details actions directed by Adm. Papp, as a result of the JIT's work, reflecting the Coast Guard's
commitment to all of those affected by this tragic yet historic event and underscoring its commitment
to the stewardship of our maritime environment.

 
Volume II includes findings on the causes, both direct and contributing, of the Macondo blowout and
the resulting explosion and fire aboard the Deepwater Horizon. In Volume II, the JIT details evidence
developed during the investigation and concludes that BP, Transocean and Halliburton's conduct in
connection with the Deepwater Horizon disaster violated a number of federal offshore safety
regulations under BOEMRE's jurisdiction. Volume II also includes recommendations for the
continued improvement of the safety of offshore operations.

 
In the wake of the Deepwater Horizon tragedy, BOEMRE launched the most aggressive and
comprehensive reforms to offshore oil and gas regulation and oversight in U.S. history. The reforms
strengthen requirements for everything from well design and workplace safety to corporate
accountability. An additional rule, which will be made available for public comment in the coming
weeks, will incorporate additional safety requirements that are related to the findings of the
investigation.

The JIT Final Report is available here.
