| Summary: | In order to improve the safety of shipping process, this paper designs a graphical user interface for calculating the static water bending moment of super large ore earner. Due to the complexity of the actual loading conditions, the long hull girder and the mobility and sinking of cargo, the irregular distribution of gravity and buoyancy along the direction of the captain of the VLCC is prominent. In the actual loading process of ships, compartment loading is adopted in many cases, and the position where the maximum shear force and bending moment appear is generally not in the corresponding position. Traditional ship strength analysis methods can be divided into two kinds. One is to establish the ship’s finite element model to calculate the ship’s strength. The other is to calculate the ship’s strength according to the simple beam bending theory. In this paper, a 360m VALE MAX ore carrier is taken as an example to calculate the local bending moment of the ship at a specific position by using QT software. Compared with the ship loading manual, the error of the program is small, and the program has guiding significance in the actual shipping process.
