Evaluation on Ship Performance in Actual Seas : Ship Speed, Fuel Oil Consumption and Main Engine Power

Abstract

Ships reduce their performance in actual seas caused by natural forces, aging deterioration and biological fouling. The speed loss, which is one of the important index of their performance, is already described in the last paper using probabilistic method. In this continuation, this paper also describes the performance of the fuel oil consumption and the main engine power using the probabilistic method. Thereafter performance evaluation of ships is attempted. From a probabilistic point view, the desirable performance evaluation is proposed.
