摘要： PROBLEM TO BE SOLVED: To automatically move a drilling part between hatches, and to automatically insert the drilling part into the hatcheds by controlling the drive of a traveling frame, a turning boom and a bucket elevator based on the movement command to move the drilling part between the hatches of a ship. SOLUTION: Because a hatch H1 at which a drilling part 25 is first carried out is preset, a column member 22 of a bucket elevator 20 is located at a hatch opening of the hatch H1, the target position where the drilling part 25 is parallel to a sea-side opening part of the hatch opening is preset based on the ship type data and the relative position data, and the movement route to move the drilling part 25 from the present position to the target position in the shortest distance without bringing the drilling part into contact with a hull is calculated. The movement commands to a traveling control device 51, a turning tower control device 52, a turning boom control device 53, an elevator turning control device 54, and a tilt link part control device 56 are generated based thereon, and transmitted to the respective control devices. The drilling part 25 is thus started to move to the designated hatch H1.
