Abstract: It focuses on the assessment of the overall strength of container ships. The basic theory of the method is to determine the local loads based on a single Equivalent Design Wave(EDW), and adjust the hull girder loads to reach the envelope values of multiple EDWs, in order to represent the calculation results of multiple EDWs at one time. It is proved that the most dangerous load case in the multiple EDWs, which may be omitted by traditional rules, able to be covered by this method. The calculation workload is able to be greatly reduced because there is no need for a large number of design wave calculations. It is applicable to the strength check and the determination of the structural design scheme in the early design stage.
