Abstract: Abstract： The wind resistance of a large containership is emphasized given the indication of the intent of the International Maritime Organization to the application of the key green ship design and operation index such as the energy efficiency design index(EEDI) and a tendency of the containership maximization nowadays. In this paper, on investigation were conducted and the wind profile was studied and compared with other experiment results from wind tunnel tests to validate the feasibility of the open wind resistance test for the wind resistance measurement in a towing tank. Besides, the wind drag force on a 3 100TEU containership with containers and superstructure was measured in the wind turbine test with a 1.0∶87.5 scale model. Through a series of container layout cases, the difference of the wind drag force was analyzed and simulated by using CFD. It is proved that open wind test is a simple and effective measurement. Through cross validation, the results are proved credible and CFD has the priority in terms of precision and detailed simulation. The wind drag can be reduced through configuration optimization.
