Abstract
Turning-Basin as one of harbor facilities is designed based on the ministerial ordinance of the Ministry of Transport, and provided for mariners as the port users. On the other hand, it is important that the mariners' intentions are reflected to the design procedure of port facilities when the details of this such as the dimensions and the layout are planned. For that purpose, it is indispensable that the design criteria to evaluate these facilities are defined from mariners' view point. In the present paper, it is considered that Turning-Basin is represented by the two elements, which are the dimension and the layout. These elements were evaluated quantitatively employing the simulation technique and the design criteria were shown, taking into account the differance of the ships, and the influence of the external force, and the design criteria proposed here will be available to each port on case-by-case basis.
