PURPOSE:To easily and safely motor a ship, by leading an eye splice carried at the front end of a muli-step cylinder device to a ship mooring bit in association with a detected signal indicating the position relative to the ship mooring bit on a quaywall corresponding to the multi-step cylinder device. CONSTITUTION:The transmission and receiving of signals between the first to third PTRs 50A, 50B, 50A and a PTR53 on a quaywall 47 causes a position of a multi-step cylinder device 9 relative to a mooring bit 52 to be calculated by and stored in a main computer 55 and the ship mooring bit 52 for accessing each multi-step cylinder device 5 is determined and is inputted in the main computer 55 from which a signal is transmitted to an auxiliary computer 56 incorporated in a base 4, for driving a turning hydraulic motor, a derricking cylinder and the multi-step cylinder device 9. Thereby, each eye splice is led and moored to each ship mooring bit 52. |
