EFFECTS OF DIFFERENT WAVE SPECTRA ON DYNAMIC POSITIONING ACCURACY

To achieve high accuracy of positioning method for ships which have good mobility and are uninfluenced by the water depth, the dynamic positioning system has come into being. More and more ships working in deepwater area tend to install dynamic positioning system. The main objective of this study is...
