In such a case, if the operating status information indicates that the mooring device of the dolphin 23 is operating, the supply device 20 is stopped. Further, when the information indicating the operating status indicates that the mooring device of the dolphin 23 is not operating, the supply device 20 is operated. Further, the liquefied natural gas replenishment support system 100 may operate the replenishment device 20 so that the replenishment device 20 does not interfere with the operation area of the mooring device based on the acquired information indicating the operating status. As a result, the liquefied natural gas can be safely replenished without interfering with the mooring device and the replenishing device 20 .

Next, hose 26 is connected to manifold 51 . In this case, if there is a difference between the diameter of the hose 26 and the diameter of the manifold 51, a reducer (not shown) may be used. Also, two hoses 26 need to be connected to respective manifolds 51 for replenishment of liquefied natural gas. Therefore, by suspending the two hoses 26 with the same crane 25 with a distance of 1.25 m, which is the same as the interval of the manifold 51, the two hoses 26 can be connected using QCDC (Quick connect disconnect coupling). It is possible to safely and efficiently connect and disconnect each manifold 51 .

The vessel 5 is then replenished with liquefied natural gas via the hose 26 . In such a case, the flow rate of the liquefied natural gas per hour may be measured using a measuring instrument such as a flow meter or a liquid level gauge of the LFV fuel tank. Also, the flow rate of the liquefied natural gas may be controlled based on the measurement results. In such a case, for example, the flow rate may be controlled so as to be set in advance. Also, the flow rate of the liquefied natural gas may be controlled based on the vessel information acquired in step S110 or the supply environment information acquired in step S130, for example. Alternatively, the properties of the liquefied natural gas may be analyzed by gas chromatography, and the calorific value of the delivered liquefied natural gas may be calculated. This enables more appropriate replenishment according to the situation of the ship 5 and the replenishment base 2 .

This completes the operation of the supply device 20 in this embodiment. As a result, appropriate replenishment of liquefied natural gas can be performed according to the mutual situation between the replenishment base 2 and the ship 5, so that the LNG-fired ship can be safely berthed directly at the replenishment base, with high accuracy and efficiency. It becomes possible to replenish with liquefied natural gas.
