Zusammenfassung:	PURPOSE: A drilling ship is provided to prevent a door driver from becoming corroded and contaminated by holding the door driver in a first holding unit and externally discharging water from the first holding unit by a water discharge unit, when a moon-pool door is completely opened. CONSTITUTION: A drilling ship comprises hull(10), a moon-pool door(30), a door driver(50), a first holding unit(60), and a water discharge unit(70). Moon pool(14) is formed in the hull. The moon-pool door is hinge-coupled in an inner wall defining the moon pool to be able to vertically rotate and opens/closes the moon pool. One end of the door driver is coupled to the moon-pool door and the other end of the door driver is hinge-coupled to the hull. The door driver supplies driving force to the moon-pool door. The first holding unit is formed in the hull to be communicated with the moon pool.
