This paper presents some experimental results about Position Mooring (PM) system applied to the barge ship. In PM operation, the station keeping in surge, sway of vessel is provided by the mooring system. In this paper, a system consisting of a barge vessel and mooring lines is mathematically modeled. The position and orientation of the vessel are controlled by changing the tensions of the mooring lines. The PID and robust control strategies are applied to evaluate the efficiency of proposed system. Experimental results of each control strategy are presented and discussed.
