Application of NAPA in Grain Stability Calculation of Bulk Carrier

The process of applying NAPA to calculate ship’s grain stability is introduced in this paper combined with calculations for a variety of loading conditions of 82000DWT bulk carrier project. NAPA BASIC macro for calculation report auto generating is compiled. The result shows that NAPA has steady performance, powerful calculation function and flexible application. NAPA can be used to calculate the ship’s grain stability conveniently and accurately.
