PURPOSE: A ballast system of a ship is provided to minimize the corrosion of an internal flow path caused by equilibrium water flowing in a ballast system of a ship and to prevent the inner flow path from being damaged by vibration and external force. CONSTITUTION: A ballast system of a ship comprises a first ballast tank, a second ballast tank, a first pipe(11), a second pipe(12), and a connection flange(30). The first ballast tank is arranged in one side of a partitioning wall. The second ballast tank is arranged in the other side of the partitioning wall to be separated from the first ballast tank around the partitioning wall. The first pipe is connected to the first ballast tank. The first pipe is formed with anti-corrosion material. A first pipe side flow path is formed in an axial direction of the first pipe in the inside of the first pipe. The second pipe is connected to the second ballast tank. The second pipe is formed with the anti-corrosion material. A second pipe side flow path is formed in an axial direction of the second pipe in the inside of the second pipe. The connection flange is installed in the partitioning wall. The first pipe is fixed to one side of the connection flange so that the first and second pipes are connected. The second pipe is fixed to the other side of the connection flange. |
