A method is described which may improve the dynamic positioning of large ships im wind and waves, especially in case of non-parallel wind and wave directions. The proposed method applies the measurement of relative motions at two opposite side locations to estimate the wave direction and the wave drift force level. Combination with the wind measurement leads to an optimum heading set-point. The potential improvements are illustrated by results of tests and dynamic positioning simulations.
