        It is very important and necessary for safe maneuvering and piloting of a VLCC to know the quantity of her sinkage and trim changes in advance when she enters into shallow water area from deep sea. It is already well known that the quantity of sinkage and trim of a vessel change when she navigates between the sea areas of different depths. In this paper, the authors induced five mathematic formulas to compute the quantity of hull sinkage and trim changes arising from the different conditions and speeds of vessels and sea depth. Also they checked and examined the conditions of 131 VLCC class vessels with the over all lengths between 200 to 360 meters and evaluated mean values of Cb, Lpp/B, Lpp/dm, the trim and mean draft(dm) of them according to the different groups of length and loaded conditions. Using the calculating math formulas and loaded conditions, the authors math tables to find the quantity of hull sinkage and trim changes due to the different size, condition and speed of vessels and the depth of sea.
