BP Exec Back on the Stand in Oil Spill Trial

NEW ORLEANS (AP) _ A BP executive who led the company’s internal probe of the 2010 oil spill in the Gulf of Mexico says his investigators didn’t explore whether top BP managers had a role in causing the disaster because they didn’t have access to employees and records from contractors.

Mark Bly has served as BP’s global head of safety.

He testified Thursday at a federal trial for spill-related litigation.

He said his team didn’t have enough information to conduct a “systemic evaluation” of what caused the blowout of BP’s Macondo well without cooperation from rig owner Transocean and other companies that worked on the project.

A report issued by Bly’s team in September 2010 focused on mistakes that rig workers made before the blowout triggered an explosion that killed 11 workers.
