The federal agency that oversees the offshore oil and gas industry says an investigation into BP's Atlantis platform in the Gulf of Mexico found some problems, but none that caused unsafe conditions.
The agency found problems with the way the company organized, stored and labeled engineering drawings and documents.
The probe stemmed from a lawsuit filed by a former BP contractor in April 2009, a year before the deadly Deepwater Horizon explosion and resulting oil spill in the Gulf. The contractor had claimed the absence of proper documentation created an increased safety risk.
The Bureau of Ocean Energy Management Regulation and Enforcement says allegations that Atlantis workers lacked access to critical drawings and that BP made false submissions to the agency were unfounded.
BP says it always maintained that Atlantis is safe.
