Recently, the size of container ships has been progressively increasing, and much attention is required for safe navigation in shallow areas such as coastal waters and ports due to increases in draft. It is necessary to understand the characteristics of ship motion not only in still waters but also with waves. Especially in shallow regions, squat due to the vertical movement of the ship can be an important evaluation factor for the safe navigation, and wave drift force acting in the horizontal direction can have a great influence on the maneuverability of a ship. In this study, a numerical simulation using computational fluid dynamics has been performed for the wave exciting force acting in the vertical direction and the wave drift force acting in the horizontal direction for a very large container vessel sailing in shallow zone. As a result, it was found that total resistance in still waters greatly increased in shallow water. Wave drift force was shown to decrease given longer wavelengths regardless of water depth. It was observed that the wave exciting force in shallow water was considerably larger than at other water depths. As wave height against the central part of the ship lowered, the aft side rose.

As ship builder companies have a tendency to pursuit the effect of scale economy, recently the ultra-large sized container ship is discussed very actively among them. It is expected that these situation will be continued for the time being. The need of accommodation re-arrangement is carefully proposed according to the tendency of ultra-large sized ship. In this paper, accommodation re-arrangement of ultra-large container ship is examined in the view of economy. We proposed separation of engine room and accommodation part through review and supplementaition of drawing generation in intial design stage. Also we investigated its merits and demerits to find out whether it can be realized or not in the view of economical efficiency. The RFR(Required Freight Rate) is considered as the objective function to evaluate the re-designed vessel. The economical benefits for increasing the number of TEU(Twenty-foot Equivalent Units)'s and the re-arranged space are analyzed in the view of ship owner and shipyards respectively.

This paper investigate the problems of standard container port handling capacity in establishing national port development plan in Korea. Considering container port developing, it's not easy to adopt container port service quality parameters such as lay time constraint of very large container ships by using the standard guideline of container port handling capacity. A simple methodology that connects vessel waiting to service time(w/s) and berth occupancy to costs has been used to evaluate the performance of a container terminal. But the total handling capacity have to be calculated by the performance of the handling system and number of equipments and layout of terminal by using computer simulation that represents of reality events needs to be performed by probabilistic techniques. A simulation model of estimation of container terminal capacity is introduced in order to establish a hub terminal for very large container ships that focus the port's quality of service and also suggest as tool for policy maker to justify a required port investment.

부산신항은 우리나라 최대이자 세계 제6위의 컨테이너화물 처리항만으로 자리매김을 하고 있다. 최근들어서 차세대의 친환경 선박으로 벙커C 연료유 대신에 LNG 연료유를 사용하는 선박개발이 본격화되고 있다. 이에 따라서 부산신항의 항만기본개발계획에 들어 있는 유류중개기지 축조 대신에 Bunker LNG(BLNG)터미널 축조를 검토하고 있다. 이 연구에서는 BLNG터미널 개발과 관련하여 초대형 컨테이너선의 남컨 및 북컨 터미널 입항접안에 장애요소로 작용하고 있는 토도의 유무 및 호란도 절개에 따른 해사안전법 상의 해상교통안전진단시행지침에서 규정하고 있는 위험요소에 대한 충돌확률과 선박 운항자의 주관적 평가를 중심으로 안전수역 확보에 대하여 종합적으로 평가, 분석하였다.

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.

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.
