Considerations
•
•
•
•
•
Which engine type?
The size of the tank?
Where do we place the tank?
Cape stone generator?
Start date of the refit?

BUNOVA CFD Simulation
Goal :
Approach :
Analysis of the explosion safety in case of gas leaks, by investigating
the ventilation rate of the LNG tank room.
Only the air flow is calculated, no actual gas leaks are simulated. It is widely accepted that for a semi enclosed
space, such as the LNG room of the Eiger, the ventilation is sufficient if the refreshment rate is more than 12 times
per hour. So the residence time in each part of the room should be smaller than 3600/12 = 300 seconds.
Conclusion : On average every 220 seconds, the engine room is refreshed
