In these days, an automatic operation technique for marchant ship is becoming higher lebel, but in the field of special work ship, it remained at lower lebel because of the speciality and difficulty. Bucket dredger is a type of dredging ship and put into a group of special work ship. It dredges sand, soil or rock with rotating buckets line which is constructed by connecting about 100 buckets. It uses 6 anchor lines for the movement of dredging such as route tracking, positioning and velocity control. The operation system using anchor line is applied another type of work ship. Automatic control for this operation requires solving the problem of interference among route tracking, positioning and velocity control. The authors approched it with modern control theory and conventional control method, and had the conclusion that generally the former is effective for every operation but the latter is adequate in case of bucket dredger. This algorithm was systemized with micro-computer and the performance was tested on real ship. The result of it was sufficent and this system was installed on the ship as the equipments using reguraly.
