초록
The shipbuilding and shipping industries have recently adopted regulations, such as the energy efficiency design index, existing energy efficiency index, and carbon intensity indicator, from international maritime organizations. However, these regulations do not reflect factors such as the country-specific sailing habits of captains, sailing patterns by route, port environments, and speed regulations in different waters. In this study, we analyze the general factors and profiles that affect the sailing modes of ships and driving modes of automobiles, identify the problems that occur when applying the concepts of automobiles to ships, and investigate their solutions. Based on this, a sailing mode generation algorithm was developed, and the sailing modes of the training ship were constructed from the sailing profile of one voyage. The results can serve as basic data for developing representative sailing mode methodologies generated based on the probability that derives various sailing profiles of different types of ships into one representative sailing mode. In addition, the representative sailing modes derived for specific waters and routes can be used to design optimization systems for new ships and measure the standardized fuel efficiency of ships with various sailing profiles.
