A new report from the National Academies of Sciences, Engineering, and Medicine identifies strategies for improving the reliability of bolts used in offshore oil and gas drilling rigs, thereby reducing the risk that a bolt failure could cause a spill of oil, drilling fluids, or natural gas into the environment. Although the oil and gas industry has made important advances in improving the reliability of bolts, there are multiple opportunities for the industry and the U.S. Department of the Interior’s Bureau of Safety and Environmental Enforcement (BSEE) to work together to further improve reliability and safety culture, the report says.
