it's true vladimir and teus on the inaccuracy, we did it two times by using truck to carry load and get the net weight of load/cargo using weighbridge and unloaded to ship. upon completion of unloading, we did draft survey to the ship and compare survey vs weighbridge figures so the difference is very small around 2 mt.
what i am not really sure is how they get the trim and correction to the water density? i know the surveyor uses table etc
pls elaborate on the whole process
