    • PROBLEM TO BE SOLVED: To provide a ship can enhancing its propulsion efficiency by taking an adequate posture corresponding to the navigating condition during the navigation. SOLUTION: An LNG ship 1 comprises a plurality of ballast tanks 17, 18 which are arranged along the longitudinal direction L of a hull 3 to adjust the posture including the trim and the draft of the hull 3, pumping devices 19, 20 for ballasting water in or draining water from the ballast tanks 17, 18, and a pumping control unit 41 for controlling the pumping operation of the pumping devices 19, 20. The pumping control unit 41 has a fuel consumption suppression mode 49 for operating the pumping devices 19, 20 so as to realize the posture that the required horse power of a main engine 11 is reduced corresponding to the navigating condition during the navigation.
