Performance prediction of full-scale ship and analysis by means of on-board monitoring. Part 2: Validation of full-scale performance predictions in actual seas

Abstract

In this paper, full-scale ship performance in actual seas, which was predicted by the method described in part 1 of the present study, was validated through a comparison with onboard monitored data. The full-scale performance of a large bulk carrier was monitored by a dedicated on-board monitoring system, and the monitored data were thoroughly analyzed and reduced to the form of performance parameters applicable to the comparison with the prediction results. The full-scale ship performance predictions evaluated in the form of shaft power increase agreed quite well with the analyzed monitored data obtained under actual operating conditions. Thus, the effectiveness of the performance prediction method presented in this study was fully confirmed.
