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.
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.
