The BBC recently reported that the United States issued a slamming smack down to BP oil spill. They called it the worst oil spill in US history, BP had poor leadership and truly without a doubt, a poor cement job by BP and its contractors.
They did it!
BP was “ultimately responsible” for rig safety, with Transocean responsible for safe operations and worker safety. BP tried to save time and money at the cost of safety, and Transocean operated normally despite the hazards, it said.

Right.. Look here is the memo on this situation. To avoid a coverup, BP admitted fault but only to an extent. The EPA also insisted on dispersants too so I don’t really know if it’s just BP or a collaborated cluster.. Commissioned in April 2010, just days after the explosion at the rig, the report also offers recommendations to improve the way the offshore drilling industry is regulated.
Issued a report by the Bureau of Ocean Energy Management, Regulation and Enforcement and the US Coast Guard Joint Investigation Team. For it echoes previous reports in concluding that multiple factors contributed to the disaster.
Poor Risk Management
The explosion was “the result of poor risk management and last-minute changes to plans. For it’s a failure to observe and respond to critical indicators. Especially inadequate in control response, insufficient emergency bridge response training by companies and individuals responsible,” it said.
