Cause & Consequence
- Uncontrolled release of a flammable gas or liquid
Specific Incident Equipment
ESDV on gas compression system
Low level alarms on the DCS system may not have been investigated at the initial failure of the LCV control. Immediate investigation may have identified that low level was present in the vessel and that the LCV was not maintaining the level above ESDV2107 trip and reset level, forcing the ESDV to compensate.
- Ensure all knock out high & low level alarms are active and monitored
- Ensure operational integrity of relevant LCVs
- Assess heat trace management across the site
