U.K. energy giant BP PLC (BP.LN) has vowed to hold itself to a higher set of deepwater drilling standards than those already prescribed by U.S. authorities as it aims to assure regulators it is ready to return to operations in the Gulf of Mexico following last year's Deepwater Horizon disaster and subsequent oil spill.

BP said it announced the new voluntary standards in a letter to the chief of the federal organization responsible for issuing
U.S. offshore drilling permits. It said the undertakings go beyond existing regulatory obligations and showed its determination to apply lessons it learned from last year's accident.

"BP's commitment in the wake of the Deepwater Horizon incident is not only to restore the economic and environmental conditions among the affected areas of the Gulf Coast, but also to apply what we have learned to improve the way we operate," said BP Chief Executive Bob Dudley.

"We believe the commitments we have outlined today will promote greater levels of safety and preparedness in deep water drilling," said
Dudley .

Drilling operations in the
Gulf of Mexico came to a standstill after the Obama administration imposed a moratorium on deep-water activity in the region following Deepwater Horizon.

Since the ban was lifted in October,
U.S. regulators have issued at least 15 deep-water drilling permits. Houston-based Noble Energy Inc. (NBL) received the first of these in late February for a project in which the largest stake is held by BP.

However, the company has yet to receive approval for any new well drilling projects.

Bureau of Ocean Energy Management, Regulation and Enforcement Director Michael R. Bromwich said: "We welcome additional safety steps and best practices that companies may decide to implement that are in addition to the requirements that are applied across the board."

Bureau officials said there is no agreement or accord in place with the company to allow it to resume offshore drilling and cautioned that today's announcement was BP's alone. Bromwich said last month that BP's applications for permission to drill in the Gulf would be treated on its own merits and wouldn't be prejudiced by last year's events.

BP's announced new safeguards include using a second set of hydraulic shear rams, which are large pincers designed to pinch close the drill pipe inside the blowout preventer in an emergency.
