The structural design against bow flare wave impacts has long employed semi-empirical calculations that were established by the results of model tests and actual damage records. This design method, however, relied very much on the assumptions on which the approximate equations were established. Thanks to the recent development and improvement in numerical analysis techniques, a bow flare wave impact phenomenon can be calculated more directly using the numerical simulation of fluid-structure interaction. Recently, Mitsubishi Heavy Industries, Ltd. (MHI) has established a more direct method of structural design against bow flare wave impacts by applying the latest simulation techniques instead of the semi-empirical methods. This design method was then applied to the structural design of new large-scale container carriers.
