| Abstract: | The structure response research of oil tanker resulted from liquid sloshing is studied in the paper. The structure strength with thinking about the influence from liquid sloshing and without are compared, including the design wave parameters, the stress distribution of the load cases with maximum torque, maximum vertical bending moment and maximum horizontal bending moment. The structure fatigue strength with thinking about the influence form liquid sloshing and without are compared, including the fatigue assessment results, the fatigue damage results according wave direction. The research conclusion about influence research from liquid sloshing on ship structure performance is of important significance for design and assessment about oil tanker. |
