説明

<p>An index that can mutually evaluate the navigation performance of ships of different sizes will promote an introduction of vessels with excellent navigation efficiency. In this study, the Energy Efficiency of Navigational Indicator (EENI) and the energy efficiency of propulsion indicator (Kn) were introduced to compare the operating performance of coastal vessels with each other. A methodology using the bootstrap was introduced to accurately identify curves of these indicators even with a small sample, because the number of coastal vessels is small. This methodology was applied to the results of sea trials of 16 coastal cement and limestone ships, and the relationship between ship energy efficiency and displacement was clarified.</p>
