UNDATED (AP) - A published report says Deepwater Horizon rig workers were concerned about safety and the condition of some equipment on board.
The New York Times cites a confidential survey done before the April 20 explosion.
A spokesman for Transocean, the owner of the rig leased by BP, confirmed the existence of the reports to The Associated Press.
The Times reports that another report to Transocean by Lloyd's Register Group found that several pieces of equipment -- including rams in the failed blowout preventer -- had not been inspected since 2000.
Guidelines call for inspection every three to five years. Transocean says most of the equipment trouble was minor and the blowout preventer was inspected according to manufacturer guidelines.
