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.
With the development of social economy, my country's marine industry has also made considerable progress, and the trend of large-scale ships has become increasingly obvious. In recent years, people have paid more and more attention to the maneuverability of large ships, especially whether large ships can navigate safely in restricted waters. In order to ensure the navigation safety of large ships in restricted waters, this article analyzes the characteristics of restricted waters and the maneuverability of large ships themselves, and analyzes the causes of some maritime accidents. It points out the navigation risks of large ships in restricted waters and proposes safe navigation. Countermeasures: Reasonably adjust the speed and timing of rudder use; maintain a reasonable quay wall distance; maintain a reasonable draught difference; make careful sailing preparations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
