Sažetak
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 to discuss the effects of different wave spectra on the dynamic positioning accuracy. First, considering some parameters of a certain dynamic positioning ship, the Response Amplitude Operator (RAO) is calculated by AQWA. Then, time domain simulations and calculations for the ship motion have been conducted by OrcaFlex based on JONSWAP, ISSC, Ochi-Hubble, Torsethaugen and Gaussian Swell, respectively. Finally, the analysis results are compared to discuss the dynamic positioning accuracy. Some useful conclusions and recommendations are obtained to lay a theoretical foundation of actual project practice.
