  • The appearance of over 10,000 TEU containerships (so called Mega-containerships) is determined. In order to operate these ships effectively, the number of these calling ports will diminish, and then feeder ships will transport cargoes from the hub-ports where mega-containerships call to the destination ports. In the hub-ports, handling containers for mega-containerships become huger, thus it is important for terminals to deal with cargo handling as soon as possible. However, the present terminal layout might have the limitation of maximum throughput per time unit. And then the transit time at the ports become longer. Therefore, we investigate the effect on some different terminal layouts with new alternatives. Actually, we discuss the ship-to-berth allocation at some adjacent berths for mega-containerships on three types of terminal layouts. First one is the conventional type consisted by some linear berths, most container terminals in the world are normally this type. Second one is the indented type consisted by linear berths and indented berths which we can handle from both sides of mega-containership simultaneously. Third one is the floating type consisted by linear berths and the floating berth. On this type, mega-containerships can moor between linear and floating berths. The merits of this type are that we can also handle from both sides of mega-containerships simultaneously, and ships can go through between linear berth and floating berths. Thus it is easier for ships to moor and leave berths. Under such assumptions, we examine the numerical experiments. In most cases, the total service times on the indented type are the longest among three types, these on the floating type are the next longer. Those reasons are that these layouts have the differences of berth occupancy obtained by the time and space axes, and whether the precedence constraints of ship service order needs or not.

  • 컨테이너 터미널은 유형별로 터미널 배치 형태, 장비 종류 및 규모 등이 다르기 때문에 생산성 및 경제성 측면에서 차이가 있다. 따라서, 객관적인 기준을 바탕으로 하여 생산성 및 경제성을 평가함으로써 각 터미널 형태에 대한 이해를 높일 필요가 있다. 본 논문은 이러한 필요성에 따라 기존의 재래 터미널, ECT 무인 터미널 그리고 Ceres 도크 식 터미널 등 현재 개장 중인 3개 터미널 형태에 대하여 총면적, 안벽길이, 투입 장비 등을 기준으로 생산성을 분석하고, 장비 구입비, 건설비, 인건비 등을 포함하는 총비용을 도출하여 경제성을 평가한다. 또한, 이러한 결과와 우리나라의 터미널 운영 환경을 고려하여 각 유형의 도입 타당성을 검토하고, 최적 유형과 유형별 도입 단계를 제시한다.

  • As the competition in the liner shipping industry is becoming fiercer, the shipping company is trying to find the way to keep the best competitive position by reducing the cost level as low as possible and offering the best quality of service to their customer. In order to achieve this goal, the selection of port and terminal that have the best quality of service and cost effective structure is essential for the shipping line, where they can only have a chance to save the money. In this context, the paper compares three European container terminals in order to understand the factors that have to be considered in the decision making process for the selection of terminal. And its advantages and disadvantages of each type of container terminal operation system were analyzed from the liner shipping company's point of view in terms of cost, time, flexibility, stability, hinterland connection, geographical position and terminal productivity. It is obvious that the cost factors are very important for liner shipping company to select their terminal. However, there might be even more important factors than the cost factors, such as quality of port and terminal service, mutual trust, and possibility of future development.
