Difference in LNG volume during transportation?
A ships loads 135,000 m3 of LNG, she reached a discharge port in 5 to 6 days while burning gas to engine room (as fuel) and other boil off gas generated simultaneously and while gauging at discharge port, it was found that the volume is same as 135,000 m3 nothing less. How is that possible as it has happened on one or two ship in a fleet. Is it something to do with LNG density or BOG density or cargo expansion contraction?
I am really looking for the answer, someone with LNG experience please answer this for me, I would appreciate.

I assume that the LNG is in atmospheric pressure. The actual volume of the tanker itself is more than 135,000 m3. The reason is so it can maintain the inner tank temperature during loading and unloading of LNG in port and as fuel using the excess LNG inside the tank.

Is this happens with all ships? or the same ship all the time?
Probably measurement error.
