THE TIME PREDICTION OF SHIP MOTIONS AT SEA

The work described in this paper is related to the time prediction of ship motions under wind, wave and current excitation. The prediction is based on mathematical models generated in real time by using system identification techniques. The applications of ship motion prediction are numerous. The potential improvement in the safety of landing aircraft and helicopters on carriers and other naval and commercial ships is of particular interest. A case study is included in the paper. Roll measurements obtained from the sea trials of a frigate are analyzed, and actual and predicted ship responses are compared. The results demonstrate that prediction of ship motions using on-line system identification methods is feasible.
