Study Notes
Procedures for Abnormal Conditions in LNG Storage and Distribution
- Abnormal conditions are controllable conditions that might cause a safety condition but have not elevated to an emergency condition.
- Taking an LNG storage tank out of service for maintenance or repair requires a written detailed procedure.
- Warming and cooldown procedures are necessary for maintenance and repair of LNG storage tanks.
- High Distribution Pressure exceeding its Maximum Allowable Operating Pressure (60 psi) is an abnormal operating condition.
- Distribution Pressure at Site #1 is typically operated at 45-50psi, well below the MAOP of 60 psi.
- Gas detection procedures vary depending on the level of methane detected, with different safety precautions and procedures for each level.
- Flame detectors that detect a fire require following the Fire Protection Plan.
- False detections caused by low temperature, glaring sun, or other causes require a specific procedure to identify and address the issue.
- A glycol leak requires protective wear, measures to stop the spread of further spill or contamination, and use of spill kits.
- Maintenance of Master Meter Dry Gas Filters requires monitoring differential pressure and changing filter elements at half of their collapsible differential pressure of 12.5 PSIG.
- All procedures require proper training and adherence to standard operating procedures.
- Safety precautions and procedures should be followed at all times to prevent accidents and emergencies.
