In Japan, there are provided tug requirements in each compulsory pilot district. However, most of the requirements only show the number of required tugs but not showing how to determine the numbers. Therefore, the conflict, which is about the requirements of tug numbers, occurs between captain and pilot sometimes. The purpose of the study is to find a method of making the practical tug requirements particularly in Kobe area and Osaka area of Hanshin Port. First, we researched the tug requirements which are used in Kobe area and Osaka area to clear the present condition of the requirements. Second, we calculated the output of required tugs by using the external force calculation. Then, we compared the current requirements with the results of the external force calculation. According to the results of the comparison, we found that the current tug requirements for Kobe area and Osaka area of Hanshin Port are applied to the condition when wind blew less than 8m/sec. Finally, we made the method of making the tug requirements using the external force calculation.
