PURPOSE: A method for repairing a ship on the ground is provided to reduce construction costs per a unit building berth by managing multiple building berths with one system in which an inner wall, a floating dock, and a heavy object transferring device are integrated. CONSTITUTION: A method for repairing a ship on the ground is as follows. A repairing ship(10) is lifted by a floating dock(20) in an inner wall(40). The lifted ship is transferred to land building berths of an inner wall site(50) by using a heavy object transferring device. The ship is repaired in the land building berths. After repairing the ship is finished, the ship is retransferred to the floating dock of the inner wall by using the heavy object transferring device. The floating dock is submerged so that the ship can be floated on the sea.
