地方港の現状と主要港との比較

Abstract

It is reported that local ports are under severe conditions in a sense of low workability. We carry out some researches on cargo handling volume of containers, number of cranes, kinds of berth and unused area in port. The obtained results are summarized as follows. (1) A characteristic of the local ports is cleared using a relation between the cargo handling volume and number of enterd ships. The local ports are classified into two groups, one has 1/3 of the handling volume per ship of major ports, and the other has 1/5. Moreover, the frequency of enterd ship tonnage for each port are also classified into 3 groupes. (2) It is well-known that the handling volume in the local ports is small. On the other hand, the possible handling volume can be calculated to be about 100, 000TEU. Using these data, we present a remaining volume for each port. It can be used for the future target for the port revitarization. (3) The unused ares for each port can be summarized, the low-used area however are hard to research. We present the ratio of the berth usage as an alternative index of the low-used area. (4) It is shown how the unused area are diverted as a short term temporary usage. (5) In the existing construction of port, the publicity is regarded as more important than the payability. So it is hard to show the lowest handling volume from the payability. If the lowest volume is calculated from the construction costs, it is clarified that it is approximately 70, 000 TEU/year.
