Cruising Performance of a Large Passenger Ship in Heavy Sea

Abstract

The authors proposed a new estimation method of wind forces and moments acting on ships based on a physical-component-model of the wind loads. In this paper, using the wind loads estimation method, steady cruising performances of a large passenger ship are estimated in heavy sea in order to assess the strong wind and waves effects. Some important characteristics of the resistance increase in steady cruising condition in heavy sea for the large passenger ship are clearly revealed in the calculation.
