Nowadays, progress is remarkable in the field of nautical instruments, such as GPS and others, and which can be utilized to acquire the precise ship position. We are developing a monitoring system for riding at anchor, and the data is taken from the modern electronic instruments aboard T.S. FUKAE MARU. At Kobe University we operated this monitoring system for more than 2 years, and during actual voyage conditions. It was used for the prediction and warning of-anchor dragging. When we observed on monitoring screens, the ship's motion in terms of the anchoring, our new system found not only the regular swinging of the ship, but also some irregular swinging. In order to help the officer of the watch to judge the anchoring status, we analyzed the ship's motion during 47 anchorings of T.S. FUKAE MARU. As a result, we can classify three patterns of swinging; 'Regular swinging', 'Circular movement focused on the bow' and 'Bulbous = Irregular concentrated movement'. The details of this research, with some discussion included, are given in this paper.
