This report presents an examination of techniques for computing current-induced forces and yaw moment on moored vessels based on experimental data or procedures from nine independent sources. No validated full-scale data were located, so only relative evaluations were possible. For the lateral and longitudinal current forces, the none sources were applied directly (or scaled) to two representative hull types. This comparison shows extreme differences among the nine methods. It is ...
Methods are presented for predicting the lateral and longitudinal steady wind drag forces and yaw moment versus incident wind angle for various ship types. These methods were developed based on experimental model data for 31 ships compiled from six independent tests. Except for hull-dominated ships, which are considered separately, the longitudinal wind drag force is computed using a constant headwind coefficient that has an accuracy of 12%. This coefficient can ...
