い、やはり船の利用効率が低下する。(Prior Art) Far-sea fishing fleets must be refueled during long-term operations. In addition, the fish that are caught must be frozen and transported to designated ports one after another.
Previously, while a dedicated tanker was prepared for refueling, frozen fish had to be transported on a separate reefer ship. As a result, tankers are empty on their return trip, and refrigerated ships are empty on their outbound trip, resulting in a problem of poor ship utilization efficiency. Therefore, it is conceivable that one ship could be used as both a tanker and a reefer ship, but in conventional reefer ships, the freezing chamber is made of wooden plywood, and the cooling system and cooling pipes are also installed inside this freezing chamber. Therefore, it was impossible to put fuel into this freezer. Therefore, it is conceivable to use some of the holds of one ship as fuel tanks and others as freezing rooms, but in this case, some holds will always be empty on the outbound and return journeys. As a result, the efficiency of ship utilization decreases.

され得る。(Effects of the Invention) As described above, the present invention includes an inner tank made of a steel plate, a cooling air descending passage formed in the inner tank, and a cooling air passage defined by a drainboard at the bottom of the inner tank, The cooling air supplied from the cooling device installed outside the inner tank is guided down the cooling air downpath to the cooling air passage under the gratings, and then sent between the grates into the inner tank for circulation. On the other hand, since the tank is equipped with a vent that can be opened and closed, it can be used as a freezing tank or an oil tank by cleaning the inside of the tank, greatly improving the efficiency of ship utilization. Cooling air flows directly into the inner tank, allowing the cargo to be cooled directly and efficiently. Furthermore, when the inner tank is used as an oil tank, fuel also enters the cooling air descending passage and the cooling air passage, so the fuel capacity is not sacrificed. Since it is fixed inside the hull through insulating joists to allow slight movement, the load applied to the inner tank can be widely distributed not only to the inner tank but also to the hull, resulting in a lightweight inner tank. The structure can withstand sufficient loads. Further, since the strain that occurs in the hull during navigation can be absorbed by a slight relative movement between the inner tank and the hull, excessive stress is not applied to the inner tank, and the inner tank can also be well protected.
