Blowout Prevention System Events and Equipment Component Failures

The 2016 SafeOCS Annual Report, produced by the Bureau of Transportation Statistics (BTS) of the U.S. Department of Transportation, presents, for the first time, insights into blowout prevention equipment (BOP) component failures reported for the Outer Continental Shelf (OCS). The report is an analytical product of the data and information collected from the BOP equipment component failure notifications mandated by the Bureau of Safety and Environmental Enforcement’s (BSEE) Well Control Rule (WCR), which covers drilling and non-drilling well operations in three regions of the OCS: Gulf of Mexico, Pacific, and Alaska.

In the report, data are organized and analyzed to illustrate patterns of BOP equipment component failures, operational impacts, failure causes, and possible data improvement opportunities. Special emphasis is placed on where component failures occurred (such as on surface or subsea BOP stacks), when component failure occurred (such as in-operation or out-of-operation), and which systems were affected (such as barriers and support systems).

Due to the reported data, the 2016 SafeOCS Annual Report covers only the reports for marine drilling rigs (platform, bottom-supported, and floating) in the Gulf of Mexico region from July 28, 2016 to December 31, 2016. The data presented in the report has been de-identified and aggregated to protect confidentiality.
