The amount of air pollutant, Sox and Nox, emitted by a ship during ocean navigation is regulated by the International Maritime Organization (IMO) to prevent air pollution on the sea. The author presented navigation optimization technologies to reduce exhaust gas by adjusting fuel consumption locally during voyages under wave conditions without consideration of tidal or ocean current, as well as restriction of main engine output and safe navigation speed under rough sea conditions. In this paper, navigation optimization technologies are improved to solve the optimization problem subject to all these additional conditions of the sea and ship operation, corresponding to actual navigation.Moreover, the effectiveness of expanded optimization technologies is confirmed for several combinations of the above conditions through numerical simulation.
