The invention relates to a moon pool and to a drillship comprising same. The moon pool is formed in the drillship, and comprises a first space penetrating through an upper deck from the bottom surface of the drillship to enable drilling, and a second space which is formed at the side portion of the first space in the lengthwise direction of the drillship, and which has a bottom surface opened toward the lower side of the drillship. As the second space of the moon pool is formed at the side portion of the first space of the moon pool in the lengthwise direction of the drillship, the moon pool has an elongate effective length, to thereby vary the vertical movement of the seawater in the moon pool and reduce resistance of the drillship during sailing. Further, a separation wall is arranged such that a top surface thereof is located at a predetermined height between the first space and the second space, to reduce the amplitude of sloshing movement of the seawater in the moon pool, and reduce ...
