Disclosed is a mud storage device comprising: multiple mud tanks arranged on a hull for drilling offshore oil, gas, and others to receive mud introduced from the seabed; a mud transfer passage arranged on the bottom of a deck of the hull to transfer the mud to the mud tanks; and a mud control part arranged along a heading direction of the mud transfer passage to selectively control the transfer of the mud to the mud tanks. The present invention prevents the blockage of the transfer passage because the transfer passage for transferring the drilled mud is arranged on the bottom of the deck to facilitate the replacement, cleaning, and others of the transfer passage, and controls the amount of the mud stored in the tanks for storing the drilled mud without using additional valves, control devices, and others. |
