Recently, in domestic shipping, a shortage of crew members resulting from the severe labor environment and the aging of members are serious problems, and there is concern about stable transportation becoming difficult because of this. The hiring of younger crew members by improving the labor environment and reducing the labor load is therefore an important target. The automatic mooring is one means of mitigating the labor load of standby operations. If the change of the mooring tension induced by tide level change and the draft change while loading can be prevented, and moreover, if the hull position can be kept automatic within the allowable limit, the labor load can be reduced. In the first paper, the simulator that calculates motions of the moored ship and mooring tensions was built, the controller was designed, and it was verified by the simulations and model experiments that performance was good. In this paper, improvement of the simulator and the controller was performed for practical use. That is, it was taken into consideration whether a fender and a hull contact by change of draft, and the number of mooring lines and fenders were increased. The good improvement effect was confirmed by the simulations and model experiments.
