New Estimation Method of Wind Forces Acting on Ships on the Basis of Mathematical Model

The new method to estimate longitudinal and lateral wind forces for ships is presented in this paper. The proposed estimation procedure is based on the mathematical model of the wind forces acting on ships. Each term of estimation method is decided by a regression analysis using many wind tunnel experimental data. This method has same accuracy level to the authors’ previous method, which was more accurate than the earlier reported prediction methods, and has more rational form of estimation rather than the previous one.
