Disaster rig owners blame BP

The owner of the rig that exploded in the Gulf of Mexico last year has largely blamed oil giant BP for the disaster.

A report by Transocean report released today said the Deepwater Horizon explosion and resulting oil spill last year was the result of a succession of well design, construction, and temporary abandonment decisions that compromised the integrity of the well and compounded the risk of its failure. The Swiss firm said many of the decisions were made by well owner BP in the two weeks before the incident.
