Blowout Prevention System Safety Events: 2018 Annual Report

This annual report summarizes blowout prevention (BOP) equipment failures that occurred during drilling and non-drilling rig operations in the Gulf of Mexico (GOM) Outer Continental Shelf (OCS). It includes analyses of the types of equipment component failures reported and key information about them, such as root causes and follow-up actions. The report also discusses opportunities to improve data quality and accessibility. This report is based on data from 1,196 failure notifications submitted to SafeOCS in 2018, the second full year of well control equipment component failure reporting, as well as aggregated data collected since the program’s start in July 2016. Overall, the amount of rig activity in the GOM increased, while reporting activity decreased from 2017 to 2018. The number of wells spud, total wells with activity, number of active operators, and number of BOP days increased. However, the number of operators reporting failure events, the number of rigs involved in those events, and the number of reported events decreased. In 2018, 14 of 32 operators associated with rig operations in the GOM reported equipment component failure events. Reporting operators accounted for 82.1 percent of wells spudded and 85.3 percent of drilling activity. The reported events occurred on 40 of the 59 rigs operating in the GOM during this period. Nearly 95 percent of reported events (1,127 of 1,196) pertained to subsea BOP systems, as opposed to surface BOP systems.
