Wärtsilä AmmoniaPac – safe handling of the fuel

Wärtsilä AmmoniaPac is a complete fuel supply system for ammonia-fuelled ships, including

  • bunkering station skids
  • storage tanks
  • main process equipment.

The control and monitoring system safely bunkers and stores the liquid ammonia and provides stable and reliable gas flow to the engines. As an important addition to the AmmoniaPac, the Wärtsilä Ammonia Release Mitigation System (WARMS) prevents ammonia release from the process system.
