The Brazilian government began urging the use of the remote-control equipment in 2007, after an extensive overhaul of its safety rules following a fire aboard an oil platform killed 11 people, said Raphael Moura, head of safety division at Brazil's National Petroleum Agency. "Our concern is both safety and the environment," he said.
Industry critics cite the lack of the remote control as a sign U.S. drilling policy has been too lax. "What we see, going back two decades, is an oil industry that has had way too much sway with federal regulations," said Dan McLaughlin, a spokesman for Democratic Florida Sen. Bill Nelson. "We are seeing our worst nightmare coming true."
U.S. regulators have considered mandating the use of remote-control acoustic switches or other back-up equipment at least since 2000. After a drilling ship accidentally released oil, the Minerals Management Service issued a safety notice that said a back-up system is "an essential component of a deepwater drilling system."
The industry argued against the acoustic systems. A 2001 report from the International Association of Drilling Contractors said "significant doubts remain in regard to the ability of this type of system to provide a reliable emergency back-up control system during an actual well flowing incident."
By 2003, U.S. regulators decided remote-controlled safeguards needed more study. A report commissioned by the Minerals Management Service said "acoustic systems are not recommended because they tend to be very costly."
