The typical recovery procedure is as follows:
- Isolate air filling line from the Engine Room to the Emergency air bottle in the Emergency Generator Room.
- Confirm the air filling valve of the emergency air bottle open
- Start the emergency air compressor and fill up the air bottle to about 15 bar.
- Start the emergency generator manually and take on the load.
- Start one of the Main Air Compressors connected to ESB. Press up any one of the air bottles.
- Make sure the fuel supply pump to the generators is open.
- Start any one generator. Confirm normal operation of running the generator and take it on load. Emergency generator ACB will be disconnected automatically.
- Restart all pumps and confirm operating normally
- Reset boiler trip and fire boiler as quickly as possible when the vessel is in port, at anchorage or under maneuvering.
- If any difficulty is encountered in firing the boiler in a reasonable time, change over Aux Engines and Main Engine to Diesel Oil.
- Once plant power resumption complete and all operations normal, stop the Emergency Generator
- Resume Main Engine operation if vessel underway.
- Restart ventilation fans, HFO and LO purifiers.
- Make power available for cargo operation etc as required.
- Confirm that all running machinery is operating normally and restart the Air Conditioning plant.
