U.S. Halts Drilling on Gulf Wells With Flawed Bolts

Feb 7, 2013
(Bloomberg)

Deep-water oil exploration has been disrupted from the Gulf of Mexico to Brazil by the discovery of faulty bolts used in safety equipment less than three years after the worst-ever U.S. maritime crude spill.

Energy explorers such as Chevron Corp., Royal Dutch Shell Plc and Transocean Ltd. said they have been directed by U.S. regulators to suspend work aboard rigs that employ General Electric Co. devices connecting drilling tubes to safety gear and the seafloor. The equipment must be retrieved so defective bolts can be replaced, the U.S. Bureau of Safety and Environmental Enforcement said in an alert issued on Jan. 29.
