CONSTITUTION: A ventilation device of a drilling ship comprises a derrick(110), a moon pool(120), an air intake member(130), and a air exhausting member(140) The derrick forms the space which is sealed from outside. The moon pool is formed in a lower part of the derrick. The air intake member supplies external air to the moon pool or derrick. The air exhausting member discharges the air flowing to the top of the derrick. |
