ESD Tests Sample Clauses
ESD Tests. Emergency shutdown (“ESD”) systems will be tested during precommissioning, commissioning or operation with LNG/Natural Gas in the system as follows. If unplanned inadvertent ESD trips occur during initial operations then the below corresponding ESD test will be deemed completed:
a. Tanks will be loaded to test the high level shutdown function; the test shall be conducted to verify liquefaction shutdown;
b. ESD shutdown will be initiated to ensure that each LNG Train is shutdown safely and in proper sequence during operation; and
c. Power failure simulation shutdown will be initiated to ensure a safe, smooth shutdown sequence is achieved during LNG Train operation.
ESD Tests. The LNG tank high level alarms and emergency shutdown (“ESD”) systems will be tested during precommissioning, commissioning or operation with LNG/Natural Gas in the system as follows. If unplanned inadvertent ESD trips occur during initial operations then the below corresponding ESD test will be deemed completed: • Each Tank will be loaded to test the high level alarm function; the test will not be done during ship unloading operations. • Ship unloading ESD tests to confirm proper and safe operation of the ESD systems for the ship unloading systems. The ESD-2 system for ship unloading will be simulated during commissioning with pins in place on the PERC interface connection. Operating procedures will stipulate that the PERC system is tested (with pins in place) prior to receipt of every LNG shipment. • ESD-3 shutdown will be initiated to ensure that send-out system is shutdown safely and in proper sequence during LNG vaporization and sendout operation. • Power failure simulation shutdown will be initiated to ensure a safe, smooth ESD-3 shutdown sequence is achieved during LNG vaporization and sendout operation.
