Reported SPPE Events by Valve Type

Sort by frequency Sort by event significance
Note(s):
  • Date refers to event date.
  • More than one type of reported event can occur within a single reported failure.
  • Order of significance (higher significance at top) is based on the extent of degradation of installed well safety systems and potential consequence to personnel and the environment.
  • Failed to open is typically an operational failure as opposed to a safety risk; in these cases, the valve is still capable of performing its safety function of containing the well pressure in a shut-in state.
  • See section titled "Failures and Potential Consequences" in Oil and Gas Production Safety System Events – 2020 Annual Report.
  • The events shown represent two SCSSV failures involving a leak of well fluids to the sea via the hydraulic control system in April 2022. One other event reported as an HSE incident was reclassified as an external leak because it did not meet the SafeOCS definition of an HSE incident, which is an event that results in consequences to health, safety, or the environment above a specified threshold (see Appendix F of the annual report). This event occurred in December 2021 and involved a spill of 5 gallons of hydraulic fluid that was contained on deck.
Contributing Factors to Equipment Events
Note(s):
Reported Corrective Actions
Note(s):
  • Date refers to event date.
  • Reporters can choose more than one corrective action, resulting in a total greater than 100 percent.
  • See section titled "How Failures Were Addressed" in Oil and Gas Production Safety System Events – 2020 Annual Report.
  • Most of the corrective actions classified as “other” involved internal cleaning of the valve, for both surface and subsurface valves.
