Study on the Wave Loads and Structural Stresses of Container Ship

Abstract

In this article ship motions and wave loads are analyzed by using three dimensional motion of the ship program. As an example of a 5500TEU container ship, the heading angles of maximum motions and loads, amplitude of movement under the action of unit regular wave, load conversion functions, conditions and RAO of middle section at different angles have been gotten. The maximum dominant load parameters are also obtained. Then the long-term wave loads are calculated through the spectrum theory, and the results are compared with the values of classification rules. At the end forces and stresses distribution of the ship hull structure under dominant wave loads are also calculated by the dynamic load method with ANSYS software. The conclusions can be used to analyze ultimate loads of the container ships, and can also be the reference of ship structural design.
