The purpose of this paper is to evaluate the quay crane productivity in automated container terminal with perpendicular yard layout. In particular, four quay crane (single trolley/dual trolley/double trolley/supertainer) are considered to evaluate the productivity on the terminal performance. Each quay crane load or unload containers by a different process. For each quay crane, two productivities are considered and compared: mechanical productivity, net productivity. As the net productivity of quay crane is significant, in this paper, an application of simulation model to simulate automated container terminal is developed and a wide variety of computational experiments were conducted.

This study is to define the Automated Container Terminal(ACT) and container terminal system. Also, we analyze the present condition of the container terminal system in Pusan port and its automation level by systems approach. And this paper aims at evaluating on the priority of R&D investment until the beginning of the second stage of New Pusan Port Project(2006). In this process we have considered 8 factors (cost, labor, area, time volume, reliability, safety, convenience) to analyze 6 subsystems. The priority order of R&D until target year by sub-systems is as follow : Cargo Handling System〉Transfer System〉Port Entry System〉Storage System(Distribution&Manufacturing System included)〉Inland Transport System〉Port Information System.

지금까지의 컨테이너 터미널은 항만 하역작업에 주안점을 두고 운영되어 왔다. 그리하여 크레인 기술 향상, 장치장의 현대화 등 많은 노력을 해왔으나 21세기가 시작된 지금은 컨테이너 터미널 내부에 각각 이루어지던 작업이 통합되어진 형태로의 운영이 필요한 시점에 이르게 되었다. 국내에서 건설하려는 컨테이너 터미널은 지금까지와는 다른 형태로 건설되어야 한다. 현재 컨테이너 터미널 운영 시스템 터미널 내부에서 발생하는 전체를 총괄하지는 못한다. 크레인 모니터링, 게이트모니터링, 작업 상황 등이 모두 다르게 되어 있어서 하역작업에 관한 내용만을 모니터링하는 수준이다. 본 논문에서 서술하고자 하는 통합 모니터링은 컨테이너 터미널 내에서 관제실에서 크레인 운전 정보, 작업 지시, 상황 보고, 게이트 모니터링, 사고 예방, 사고 발생시의 경보 등을 모두 하나로 묶는 문제 파악에서 부터 해결 방안 제시 등, 첨단화된 지능을 갖춘 컨테이너 터미널을 구현하는데 필요로 하는 내용들을 서술하여 그 방법을 제시 하고자 한다.

This study aims at calculating berth length required of the given volume of containers. For this, unlike previous studies assuming 300,000 TEU per berth as the capacity of a berth, this study attempts to apply more realistic situation such as the distribution of vessel size, lifts per vessel, berth time by vessel size, and average berth occupancy ratio. the result are compared with that of Pusan New port planning.

In order to construct an efficient monitoring system for major port cities in Korea, the first step to build and manage related laws and institutional infrastructure with strengthen the cooperation of the relevant agencies, regional port authorities, and port corporations. Second, for the management of air pollutants emitted by ports, a management system should be established through systematic inventory source inventory and real-time monitoring system. Third, active countermeasures should be established to reduce the emission of air pollutants by sources such as ships, harbor equipment, and trucks. This will improve the air quality of major port cities and move them to clean port cities.

The purpose of this study was to draw out success factors of port operation for New International Passenger Terminal(NIPT) in Incheon Port using the fuzzy method. In this study, the success factors of port operation were firstly selected by literature review and finally adopted them by in-depth interview with experts who had working experiences over 15 years in the field of Korea-China Carferry shipping business and stevedoring business. Success factors of port operation of the NIPT have been classified into four principal factors such as 'land's use side', 'productivity side', 'cost side' and 'services side', and the comparative analysis was conducted among success factors of port operation. According to the results of analysis, in terms of "land's use side", securing CY space of full-empty containers(0.857) was the most important factor. Among detailed factors of "productivity side", building terminal automation system(0.806) was significantly needed. In the factors of "cost side" and "service side", land rental costs(0.861) and schedule management of berth operation(0.798) were selected as the most important factors. Consequently, new international passenger terminal has implications that the main port operations should focus on reasonable rents calculation, ensuring proper space of CY, and building automation system of terminal, There is a need to proceed to conduct a comparative study of the same operating mode of an international passenger terminal.

Busan New Port, under construction aiming for the hub of Northeast Asia and Partly in operation, had damaged up to 48 billion Won due to Typhoon 'maemi' in 2003. The present criteria of domestic harbor design only describes about the critical wave height with respect to the size of vessel for harbor tranquility. The berth operation ratio which represents the annual available berthing days is depending on the efficiency of cargo handling work and this depends on the motion of the moored vessel due to the wave action and the characteristics of cargo gears. The motion of moored vessel might be related not only to the wave height but also to wave period. Furthermore, the berth operation ratio relies on external forces such as currents and winds, including the characteristics of mooring system and the specification of the moored vessel. In this study we only deal with berth operation ratio in normal sea state, considering wave and current by measured data and numerical calculation. Especially we tried to evaluate the berth operation ratio for each berth adopting the variation of dredging and reclamation plan and the change of wave environment during the process of the new port construction. For better understanding and analysis of wave transformation process, we applied the steady state spectral wave model and extended mild-slope wave model to the related site. This study summarizes comparisons of harbor responses predicted by two numerical predictions obtained at Busan New port site. Field and numerical model analysis was conducted for the original port plan and the final corrected plan.

항만 내 대표적인 하역장비로는 RTG와 YT가 있으며 주로 디젤엔진을 사용하고 있다. 항만의 그린화 및 무인화를 위해 물류장비의 전기동력 전환의 필요성 증가 및 전기동력 충전을 위한 유선 또는 무선 충전기술 등이 고려 되고 있다. 본 논문에서는 항만에서 운영되는 전기식 YT의 운영 패턴을 고려해 수시로 충전이 가능한 무선전력 전송시스템을 제안하였다. 또한 제안한 시스템의 검증을 위해 실험용 시스템을 구축하여 전력전송 용량 및 효율실험 결과를 통하여 타당성을 확인하였다.

In order for Busan New Port to secure more trading volumes than the competing ports at home and abroad, an alternative plan for the new port management policy needs to be sought. By the way, aiming to minimize trial and error while maximizing effect in establishing and driving the new port management policy, there is necessity of referring to the developmental strategies of the advanced ports such as Singapore and Hong Kong that are possessing the globally leading position as well as maximizing the substantial value added and the employment-creation effect even qualitatively. Accordingly, the purpose of this study is to propose for a reasonable development strategy for Busan New Port in line with conditions and characteristics of Busan New Port by comparing and analyzing conditions and characteristics of these two advanced ports and by comparative analysis on the developmental strategy according to this.
