• As we know, due to wind action, a ship at anchor sways periodically, and this characteristic movement can be called a swinging pendulum movement. It is very difficult to understand and to explain such a complicated phenomenon because of its complexity on dynamic mechanism. To help understand this difficult phenomenon, the authors developed the integrated simulation system (ISS) for educational use. ISS uses various outputs which, when produced from a mathematical model simulating a ship at anchor, create an animation. This simulation system is a visual educational system, which not only has the function of simulating a ship at anchor, but also displays relevant information in real-time. The system can also estimate the danger of dragging anchor and show how the anchor-dragging mechanism works. To verify the educational effect of ISS, an experiment was performed, with impressive results. Students felt that a lecture supported by ISS was easy to understand and believe that it is necessary. The improved educational effect when studying the swinging movement of a ship at anchor was confirmed using animations produced by ISS. As a visual study resource, ISS and its animation provide a better understanding than a typical lesson in a classroom because of its simplicity. We believe that ISS can be used not only for educational purposes, but also as an assessment system for experiments that evaluate the safety of a ship at anchor. Such a system may be useful to researchers in other field. This paper discusses the usefulness from the viewpoint of ISS's educational use.
