The present invention relates to a system to automatically relieve pressure of a moon pool section of a drillship. More specifically, the system to automatically relieve pressure of a moon pool section of a drillship, rapidly and artificially eliminates negative and positive pressure generated as the moon pool is formed on a drilling area through a rotation of a fan by a motor. To achieve this, the present invention comprises: a ship body forming the moon pool; a weather-tight structure covering the moon pool of the ship body to form the drilling area, having a ventilation hole on one side thereof; a fan installed in the ventilation hole, and rotated in a forward and reverse direction by the motor; a pressure gauge installed inside the drilling area measuring the pressure; and a control unit rotating the motor in the forward and the reverse direction when a positive pressure or a negative pressure is generated in the drilling area through pressure measurement by the pressure gauge, relieving pressure in the drilling area. |
