Deadweight cargo capacity Calculation

Deadweight Cargo Capacity Calculation 1. New DWT: The MV “XXXXX” has DWT 56.838mt and 12,82 m SSW draft. However, we have draft limitation @ Itacoatiara. So: (MV XXXXX Draft) – (Itacoatiara FW Draft) = 12,82 m – 11,5 m = 1,32 m = 132 cm Then, 132 cm x (TPC = 58,8mt) = 7.761,60mt New DWT = 56.838 – 7.761,60 = 49.076,4mt Unfortunately, this is not correct. As we have seen before, the water density impacts on the DWT. Typical load lines for a vessel. When the vessel reaches the sea water it will rise to the summer load line level. It is important to take advantage of the FWA because there will be a loss of cargo carried, and therefore a loss of revenue, if the vessel only loads up to the summer load line level in freshwater. In this example, the draft given is for FW. So, our draft limitation is even worst.   So, we have to re-calculate the draft limitation to SSW: 11,50 ÷ 1,025 = 11,22 m, SSW draft. The New DWT is 56.838mt – (12,82 m – 11,22
