This paper presents an interruption cost model of the feeder considering the local characteristics. KERI's survey results for the customers interruption cost are used through the research. Interruption cost of the feeder in a city is calculated in the ratio of customer's types. The customers consists of residencial, commercial, industrial and public type. The proposed method is applied to calculate interruption cost of the feeder in a small city and a metropolitan aria.

In these days, 8,000TEU container ship service launches in shipping service at latest based on the economy of scale, unit cost related with ship operation on ocean decreases in proportion to increase of ship scale and mega ship over 10,000TEU is on planning. Most of the exiting researches have performed from the perspective of total operation cost from mega port to mega port. However, the purpose of this paper is to estimate economic efficiency by ports selected Hub port from total cost point of view, operation cost, port charge, feeder cost, etc.

본 연구는 환적화물을 처리하는 모선사, 피더선사, 하주 등의 항만물류주체의 업무처리 생산성과 효율성을 제고하기 위한 정보시스템, Transhipment Container Handling System (TCHS)을 제시하였다. 국내의 환적화물에 대한 업무처리는 일반적으로 선사와 피더선사간의 환적화물계약업무 모선사의 환적화물을 피더선사에게 할당하는 업무, 마지막으로 미처 할당되지 못한 모선사의 환적화물과 피더선박의 잔여 선복을 거래하는 업무와 같이 3부분으로 구분된다. 그런데, 현재 이러한 업무를 처리함에 있어 개별적인 접촉과 적절한 정보시스템이 지원되지 않아서 많은 비용, 노력, 시간이 소비되고 있다. 그래서 본 연구에서는 환적업무에 관련된 항만물류주체의 요구조사를 통해 환적화물업무를 처리함에 있어 생산성과 효율성을 제고할 수 있는 정보시스템을 제안하였다. 본 연구에서 제안한 시스템은 현행 거래를 유지하면서, 각 업무의 효율적으로 지원하기 위한 시스템으로 온라인 계약지원시스템, 자동할당시스템, 협상기반 e-Marketplace 시스템으로 구성된다.

Recently, 8,000TEU class containerships has started operating the shipping service and the mega-containership of over 10,000TEU is on planning. A unit cost in relation to shipping service is decreased by the bigger ship based on the economy of scale. Most of the previous studies have been performed and focused on the total operation cost from mega port to mega port. However, the purpose of this paper is to estimate economic efficiency of selected hub ports from point of view of total cost such as service cost(or operation cost), port charge and feeder cost, etc. First, the service-network of mega containerships is based on data of a domestic shipping company operated main line and economic analysis of individual scenarios on the cost and traffic when 10,000TEU mega containerships offer the services. The three scenarios presented in this paper set up the hub ports which are the port of Busan, Shanghai and Yokohama The results show that port of Busan is economically the most efficient one among others.

This paper first tries to analyze total sea transport costs for the transshipment in Busan Port in comparison with direct transport to 4 Chinese Ports, Dalian, Tinajin, Qingdao and Shanghai, based on vessel operation scenarios. The results found that the transshipment in Busan port for the 4 Chinese ports are more expensive than the direct calling to the 4 ports, which implies that Busan port needs to make compensation as an incentive to the carriers providing transshipment service to it in order to keep their royalty. For the compensation, it suggested a method of calculating the Container Terminal Facilities Leasing Fee to levy additional revenue by port authority.

Recently, China opened Yangshan port and provides a variety of benefits for shipping companies. Japan plans to reduce logistics costs and improve efficiency through the established 'super major ports' project. According to the 'hub and spokes' system, the number of direct calls toward North-Chinese ports are increasing. This changing environment has negative effects on the amount of transshipment cargos in Korean ports. In order to make a hub port of a domestic port, it is necessary to develop northeast Asian Feeder networks. Therefore, this paper analyzes the structure of northeast Asian feeder networks through the case study of European feeder networks strategy. Finally, we suggests the plans to reinforce feeder networks, which are strategic terminal operation, strategic alliances between shipping companies and port co-operation, for win-win strategy in the competitive northeast Asian market.

Amid global economic crisis and skyrocketing oil prices, container shipping companies have raised a sustained series of efforts to reduce vessel operating costs. Under these circumstances, the Grand Alliance has decided to install the dedicated feeder instead of additional vessels in the CCX(Central China Express) and the NCE(North China Express) route. In other words, a vessel in a trunk route is transshiped by a dedicated feeder vessel in Busan port that is a transshipment port, rather than calling at Northen China port. In this study, the actual operating data of Grand Alliance container services were analyzed to determine the economic effect of transshipment through a dedicated feeder service. In this way, the Grand Alliance are saving vessel operating expenses in 'NCE' and 'CCX' routes, making the slow steaming of vessels possible in these trunk routes.

Many shipping companies have suffered about high oil cost and environment regulation as people are concerned about the environment, therefore concentrating on energy using efficiency of the ship. The Skysails Company of Germany developed Skysails System for 4 years, making Shipping Company take interest under such situation. Skysails System uses a large kite in the ship, decreasing fuel expenses. So examination and utility analysis on Skysails System application are a necessity by using weather condition in the Coastal Waters of Korea where feeder network was well-developed. As a result, we could find out the system's efficacy on fuel saving and environment cost saving.
