of the most advanced customers

As the move towards LNG fuel gathers pace in the marine industry, it is essential that crews are thoroughly and expertly trained on handling the related systems. This new simulator is designed to raise training levels on LNG bunkering and supply systems, and will therefore also raise onboard safety levels.

Detailed physical modeling, including the following effects:

  • LNG thermodynamics and phase transition in tanks, piping, heat exchangers
  • LNG composition corresponds to the selected source of bunkering
  • LNG weathering due to boil-off process in the tank
  • Dilution of fuel gas with nitrogen, used to purge the system
  • Methane number and Lower Heating Value affecting the engine operation
