Transocean Blames BP for Deepwater Horizon Rig Disaster

Transocean Ltd. said its internal investigation found BP Plc was largely responsible for last year’s fatal drilling catastrophe in the Gulf of Mexico and reiterated its refusal to help BP pay claims stemming from the worst U.S. offshore oil spill.

Transocean, owner of the Deepwater Horizon rig that was destroyed in the April 2010 blowout of BP’s Macondo well, said today in a statement that the disaster resulted from BP’s faulty decision-making and inadequate attention to risk management.
