According to an embodiment of the present invention, a trolley seat structure for a drillship comprises: a main deck where a moon pool is formed; a reinforcing unit composed of a vertical plate vertically formed downward from the main deck and has a penetrating hole for access, and an inclined plate which forms an inclination toward a side wall of the moon pool on the vertical plate in order to support a trolley by protruding from the inner circumferential surface of the moon pool; and a supporting unit vertically placed upward on the main deck placed on a row with the vertical plate, and has a shorter length than the vertical plate. The trolley seat structure for a drillship has a penetrating hole on the vertical plate so that a worker can easily access inside the trolley seat structure, thereby facilitating work such as painting and improve work efficiency. |
