But on this article, we are to discuss regarding secret behind bunker calculation which may lead to loss of product to the opposition party.īasically, bunker is calculated in weight, following the formula: Mass = Volume x Densityĭuring shipbuilding project, each vessel is provided with bunker and water tanks as well as its capacity in a separate table in which each tank capacity in volume marked sequentially with levels of sounding or ullage also with correction factors under various trim and heel conditions of the vessel. We have in the previous article discussed on ship bunkering operation and things involved. Therefore both parties eyes are always at a watch and it becomes the game of brain. The receiver never wishes to lose a drop neither the supplier wishes to give out more that request.
