전 세계 국제무역거래의 80%가 해상운송으로 이루어지고 있음에 따라, 연 6%로 세계 컨테이너 물동량의 증가가 전망됨에 따라 선박기인 온실가스의 증가에 대한 관심과 규제가 강화되고 있다. 즉 IMO 제62차 해양환경보호위원회에서 선박기인 온실가스 규제방안으로 EEDI와 SEEMP를 도입, 현재 발효 중에 있으며, 각 국의 항만당국 또한 대기오염 등의 환경규제 정책의 일환으로 그린 또는 에코포트 정책을 수립하여 이행 중에 있다. 이러한 해운환경의 변화로 인하여 해운선사는 글로벌 경쟁력 강화와 환경규제에 대응하기 위하여, 선박의 대형화를 통한 규모의 경제 실현은 물론, 급등하는 유가와 환경규제에 대비하여 고 에너지효율 및 저탄소 선박에 대한 수요가 늘어나고 있다. 이에 일본, 싱가폴, 노르웨이 등 EU 국가 등의 해운 선진국들은 1990년대 후반부터 친환경 선박의 개발에 대한 국가적 프로젝트를 체계적으로 이행해 오고 있으며, 이를 통한 친환경 선박기술의 확보와 친환경 선박시장의 점유율을 높이고 있는 추세이다. 따라서 본 논문은 선진 해운국가들이 수행중인 친환경 선박개발의 현황에 대한 벤치마킹을 통하여 상대적으로 뒤쳐져 있는 우리나라 친환경 선박개발 방안을 위한 여러 정책적 제안을 하고자 한다.

Busan Port is being operated inefficiently by a number of container terminal operators, which are dispersed in small groups. In particular, the small terminal at Busan Port is causing the dispersion of quantity, the increase of ITT cargo and the occurrence of a ship waiting at sea as the ship's Alliance became larger in 2016. As a result, studies such as integrated operations for the larger container terminals are being conducted. Therefore, in this study, we intend to set up a type of integrated operation for terminals at the new port of Busan and measure the practical effects through simulation to present an ideal direction for integrated operation.

This paper is concerned about applying the AHP(Analytic Hierarchy Process) for a priority analysis of equipment operation plan to improve productivity of the container terminal in Gwangyang port. In this study, main elements of container terminal are assumed as into yard equipment area, transport equipment area, berth equipment area and C/Center area. A questionnaire is used to collect the opinions of equipment operating department and operational planning department. On the whole, the result of the analyses reveals that the most important area is yard equipment area. Examining each department is responses, equipment operating department preferred the C/Center area to other areas, on the other hand, operational planning department preferred yard equipment area. The result of this study suggests some guidelines for deciding priority of operation plan in the container terminal.

Due to the financial crisis in 2008, the world economy collapsed leading to an increase in oil prices and a decrease in freight by shipping. To overcome this crisis, major shipping companies ordered larger ships, changed their trading route and improved operating of ships to overcome deficits. In particular, low-speed navigation was much favored by many companies so that it can reduce fuel consumption. However, the long-term operation of high-speed optimized engines in low-speeds has affected the jacket cooling fresh water (J.C.F.W.) system as they fail to maintain the normal operational temperature. The temperature of J.C.F.W. system dropped leading to low temperature corrosion. As a result, when the engine is operating at minimal load the functioning of existing J.C.F.W cooler is decreased and the use of fresh water generator is substantially limited. Therefore, an improvement in the functioning of J.C.F.W. system is necessary. In this paper, in order to review the improvements required for the operation of J.C.F.W. of low-speed operating marine diesel, an experiment was conducted by comparing and analyzing the results of the main engine J.C.F.W. system of a Panamax class bulk carrier 82k and a Cape class bulk carrier 180k by installing and uninstalling the J.C.F.W. Cooler. Thus, this paper proposed an improved design of the J.C.F.W. system that is suitable for the present low-speed operation.

Port industry has achieved a remarkable growth with a help from increase in container shipment and above all, transshipment that reflects international competitive power of Port industry amounts to 36% of the national harbor shipment. Therefore, this study speculates the impact of Port industry on national economy using the inter-industry relation table. As it considers the reason why international competitive power in Port facilities decreased as absence of investment, it is to present an effective investment plan for Port industry. Though Port industry as one of main national key industries play an important role in production of national economy, it has been evaluated as having relatively less importance. And when Port industry is managed independently, relying on foreign countries without improvement, price increase due to improper agreement of foreign enterprises and problems relating to securing safe transportational vehicles will have tremendous impact on national economy. And they should try to create added-value and support re-export of the exported and imported shipment through their processing and packaging by making Port zones bonded area. production of national economy, it has been evaluated as having relatively less importance.

Container Vessel is becoming larger and faster thanks to the rapid growth of global trade and development of technology. Therefore, 15,000TEU vessel is expected to be ordered in near future. Every nations in north-east Asia are facing strong competition to be logistics hub to get the initiatives of logistics in response to the rapid change of logistics environment. According to the globalization of economy and major ports in this region also are trying to catch big shipping line for their survival. Considering above circumstances of the advent of ultra-large container vessel and spoke-and-hub strategy, it is inevitably necessary to make a fast and accurate vessel job in the terminal in order to be a leading port To meet this objective, current vessel planning system has to be improved innovatively. Therefore, this thesis propose multi distributed vessel planning system which enables multi loading/discharging planning with several planner simultaneously for faster and more accurate than existing planning and enhances quality of planning through information sharing among planners. Also this thesis uses simulation through Arena to verify the efficiency of this multi-distributed vessel planning system.
