Transocean: Coast Guard report on oil spill flawed

The owner of the oil rig that exploded in the Gulf of Mexico last year says a Coast Guard report that faults the company for a poor safety culture and other shortcomings that preceded the disaster is full of errors.

Transocean said in a 112-page response submitted Wednesday to the U.S. government that the April 22 draft report should be corrected.

Switzerland-based Transocean insists the blast did not result from poor upkeep, that the blowout preventer was properly maintained and that the general alarm on the rig did not fail to operate automatically.

Multiple investigations have blamed a cascade of failures by several companies, including Transocean.

The April 2010 rig explosion killed 11 workers and sparked the worst offshore oil spill in U.S. history.
