[3 Explanation of effect]
As described above, the ship fuel supply method according to the embodiment of the present invention includes a fuel loading process (S104) for mounting the storage facility 20 transported by the fuel carrier 40 on the fuel supply source ship 10 and a fuel supply source. The fuel supply step (S108) of supplying fuel from the storage facility 20 on the ship 10 to the fuel supply destination ship 60 is included. In this way, by using the fuel supply source ship 10 capable of mounting the storage facility 20 transported by the fuel carrier 40, fuel can be supplied to the fuel supply destination ship 60. As a result, fuel can be supplied to the fuel supply destination ship 60 without using a dedicated bunkering ship.

Therefore, there is no need to build, own or use the right to build, own or use a dedicated bunkering vessel, and there is no need for a dedicated fuel shipping berth for a dedicated bunkering vessel. Since the dedicated fuel shipping berth is generally shared with ocean-going vessels or close to the ocean-going vessel dedicated berth, it is necessary to adjust the usage schedule of ocean-going vessels and berths. By eliminating the need, it is not necessary to adjust the usage schedule. Since it is not necessary to adjust the usage schedule, the fuel supply time to the fuel supply destination ship 60 can be flexibly adjusted, which enhances convenience.

In addition, the fuel supply source ship 10 on which the storage facility 20 can be mounted (the fuel carrier 40 can be mounted) and the fuel carrier 40 such as a tank lorry are technologies for which safety has been established, so that safety is ensured. can. In particular, the demand for small ferries that can be used as the fuel supply source ship 10 is decreasing due to the development of the road network, so it is possible to utilize such small ferries (used small ferries) and improve economic efficiency. You can expect it. Further, if the fuel carrier 40 can be owned or dispatched, it is possible to enter the fuel supply business (bunkering supply business) to the fuel supply destination ship 60, so that the barrier to entry to the bunkering supply business is lowered.

Further, even when the fuel supply destination vessel 60 is in cargo handling or passengers getting on and off, fuel can be supplied (bunkering supply) to the fuel supply destination vessel 60, and the operating rate of the fuel supply destination vessel 60 decreases. Can be suppressed. Bunkering supply can also be performed at the anchorage of the fuel supply destination ship 60. Further, since the fuel supply source ship 10 may move linearly on the sea toward the fuel supply destination ship 60, the travel distance may be shorter than that of a truck (tank lorry) moving on land to supply fuel. , The movement efficiency will be improved, and the range of activities will be widened. In this way, the time and place for bunkering supply is widened. Further, when the storage facility 20 is disembarked from the fuel supply source ship 10, the fuel supply source ship 10 is in a state in which no dangerous goods are loaded, so that the crew can be replaced even if the cargo is not being handled.

Further, in the fuel loading process (S104), the fuel carrier 40 is mounted on the fuel supply source ship 10 together with the storage facility 20.
