BP sued Cameron International and Transocean yesterday (April 20th), exactly one year after the Deepwater Horizon
oil industry explosion.
The oil giant claims that the disaster, which killed 11 men, was contributed to by both companies.
Suing rig owner Transocean for $40 billion (£24.28 billion) in damages, BP states that all the safety devices in place on the rig failed.
Meanwhile, the company suggests that Cameron International is responsible for the design of a faulty blowout preventer - something that it says also contributed to the disaster.
Following the event, BP lost some $40.9 billion, which it hopes to claim back in damages from the lawsuits.
Recently, Reuters reported that the firm came close to being awarded a safety accolade.
It revealed that the company was on the shortlist for the innovation in safety gong from Oil & Gas UK, however it narrowly missed out.
Instead, the accolade went to NATS, an air traffic control group.
