HOUSTON — A 2-foot-long metal clamp that failed to cut a pipe on the ocean floor may be to blame for the catastrophe.
All subsea oil wells are equipped with steel blades known as shear rams that are supposed to slash through the pipe at the top of the well during dangerous pressure surges and close off the flow. A 2002 study commissioned by the Minerals Management Service, the agency that oversees the offshore oil industry, found 50 percent of the shear rams tested failed to cut through pipe and halt the flow.
The shear ram is part of a piece of equipment known as a blowout preventer that sits atop a well to reduce the force at which oil and gas travel to the surface.
