최근 중국 동북 3성과 극동 러시아지역의 개발전략은 현 정부의 유라시아 이니셔티브 국가전략과 맞물려 그 중요성이 배가되고 있는 실정이다. 자루비노항 등을 유라시아 물류네트워크의 허브로 적극 활용해야 한다. 본 연구는 현실적 변화가 뚜렷할 중국 동북 3성을 포함하여 우리나라의 투자가 병행되고 있는 러시아 극동지역, 기타 몽골지역을 대상 존으로 삼고 자루비노항을 경유 가능한 물동량 수요 여부와 예상 품목 등을 전망하였다. 현지의 관련정보 등의 부재를 극복하기 위하여 우리나라의 기존 정보와 원단위를 활용하였다. 이는 파일롯 연구로써 동북 3성 전역을 대신하여 지린성의 산업단지시설에 국한하여 이를 도출하였다. 전통적인 교통 4단계 수요추정방법을 근간으로 운송 분야에 적합하게 수정, 보완한 방법론을 제시하였다. 본 연구는 유라시아 동북지역 물류에 대한 인식제고와 함께 정부가 의지를 가지고 추진하고 있는 해당지역 물류정책에 시사점을 제시하는데 기여한 측면이 있다고 판단된다.

본 연구는 국내 액체화물량이 가장 많은 울산항에서 발생한 해양사고 통계자료를 토대로 해양사고 위험도와 취약성을 분석했다. 울산항에서 발생된 해양사고 발생 위험성, 환경피해도, 환경오염사고 취약성에서 상당히 취약한 것으로 드러났으며 분석결과를 바탕으로 향후 울산항에서 발생할 가능성이 높은 해상사고 시나리오와 사고대응전략을 마련하였다. 또한 울산항에서 발생한 대형 해양오염 사고에 대비하기 위한 대응전략으로서 제어장비와 기반인프라를 구축하고 제어센터를 설립하여 해양사고안전 기능을 통합하는 것이 필요하다고 판단된다. 특히, 울산항과 같이 액체화물특화 항만의 경우 물동량의 규모나 해양오염사고의 빈도를 볼 때, 안전관리 상설기관의 유치가 절실하며 안전항만을 구축하는데 필수적으로 고려해야 할 것으로 사료된다.

As per the rapid development of world economics the marine traffic volume was increased accordingly and caused frequent disasters in human lives and natural environment in the consequence of accidents. As the result of the above they started to establish Vessel Traffic System(VTS) and separation scheme in waterway from 1960' to prevent the marin traffic accident but the problem of safety at sea appears now as neither fully defined nor sufficiently analysed. At the present, the dominant factor in establishing the strategy of marine traffic has been safety of navigation concerning only with the ship, but the risk of society derives almost wholly from the nature of cargo. To measure the degree of danger for each ship there is suggested concept of safety factor numbers denoting the level of latent danger in connection with ship and her cargo. In this paper, where the strategy of VTS is put on controlling density of safety factor for control area. it suggested algorithms how to assign the vessels and also to get optimal sequence of vessels located to a sector in the sense of minimizing the passage delay. For the formulation of problem, min max and 0-1 programming methods are applied and developed heuristic algorithm is presented with numerical example to improve the efficiency of calculation.

Yangtze River channel is in natural condition for a long time. There are more to be done in grade of navigation and transport. Since 1980's the rate of vessel in JiangSu channel is going up every year, especially for ocean vessels. Meanwhile, the serious factors such as no sailing at night have become a battlement causing the long period for vessels, high cost for shipowners, lower competitiveness for JiangSu ports along the Yangtze River. It also can not meet the port logistic development. After the Ships' Routeing in JiangSu has been carried out. It has improved the safety of navigation in JiangSu area and reduced the risk of pollution or other damage to the marine environment caused by ships colliding or anchoring in or near JiangSu channel. By analyzing, compareing, calculating and model forecasting. The main focus of the paper is put on the study the development of port, channel in JiangSu and efficiency in many fields. Navigation efficiency of the sailing at night; Safety efficiency of reducing the risk by ships; More efficiency of the higher cargo volumes of the other ports in Yangtze River with the increase cargo volume of JiangSu ports along Yangtze River. The purpose of this study is: To get the social and economical efficiency after the Ships' Routeing in JiangSu has been carried out. Also the role of the Ships' Routeing of JiangSu in the development of Port and Channel.

A new method for ship Inner Shell optimization, which is called Parametric Inner Shell Optimization Method (PISOM), is presented in this paper in order to improve both hull performance and design efficiency of transport ship. The foundation of PISOM is the parametric Inner Shell Plate (ISP) model, which is a fully-associative model driven by dimensions. A method to create parametric ISP model is proposed, including geometric primitives, geometric constraints, geometric constraint solving etc. The standard optimization procedure of ship ISP optimization based on parametric ISP model is put forward, and an efficient optimization approach for typical transport ship is developed based on this procedure. This approach takes the section area of ISP and the other dominant parameters as variables, while all the design requirements such as propeller immersion, fore bottom wave slap, bridge visibility, longitudinal strength etc, are made constraints. The optimization objective is maximum volume of cargo oil tanker/cargo hold, and the genetic algorithm is used to solve this optimization model. This method is applied to the optimization of a product oil tanker and a bulk carrier, and it is proved to be effective, highly efficient, and engineering practical.

With the recent increase in the volume of liquid cargo transportation, there is a need for STS( Ship To Ship) globally. In the case of the STS mooring, the safety assessment should be conducted according to other criteria because mooring is different from the general mooring at the quay, but there is no separate standard in Korea. Thus in this study, STS mooring simulation and sensitivity analysis using OPTIMOOR program, the numerical analysis program, was conducted to identify the characteristics of the STS mooring. The target sea modeled the Yeosu port anchorage in Korea and the target ship was selected as the case of VLCC (Very Large Crude Oil Carrier)-VLCC. Through the numerical simulation and sensitivity analysis, the characteristics of STS mooring were identified. Also based on these results, we focused on establishing the standard for STS mooring safety assessment. Numerical simulation results show that the STS mooring safety can be changed according to a ship's cargo loading condition, pre-tension of mooring line, sea depth, encounter angle with the weather, and the weather condition. Additionally, the risk matrix is prepared to establish the safe external force range in the corresponding sea area. This result can be used to understand the mooring characteristics of STS and contribute to the revision of mooring safety assessment criteria.

국내 항만산업의 발전과 더불어 내륙운송 산업 또한 발전하였으며 이에 따라 항만은 내륙과 연결하는 거점 역할이 증대되고 있다. 이에 따라 항만과 각 지역들 간의 화물 흐름에 관한 연구가 활발하게 진행되고 있다. 하지만 우리나라 기종점 통계 자료는 단순하게 O/D분석방법을 이용하여 구축되어 화물의 정확한 운송경로를 파악하기 어려운 문제점이 있다. 또한 이러한 통계자료는 철도를 이용한 복합운송을 제대로 고려하지 못하는 단점이 있다. 이에 따라 본 연구에서는 P/C개념을 도입하여 부산항을 입출항하는 컨테이너를 대상으로 화물경로분석을 실시하여 화물의 정확한 운송경로를 파악하고 이에 따른 각 지역 간의 기종점 자료를 재구축하였다.

The Pohang Youngilman Port is the only international trade port in the Daegu-Gyeongbuk region, but its cargo throughput has been stagnated since its opening. Finding out ways to revitalize the port has been a big issue in the region, taking its potential business effects on the surrounding areas into consideration. This study, therefore, aimed to critically evaluate the government policies and empirically analyze business environments of the Pohang Youngilman Port as a fundamental to reach solutions for its revitalization. The policy evaluation showed that there are discrepancies in viewing contexts, implementations and mechanisms of the port at each government level, which resulted in implementing various but inconsistent solutions. Also, the interview results were analyzed to point out the fundamental problems, such as limited cargo volume due to weak hinterland development, lack of shuttle shipping between Busan New Port and Pohang Youngilman Port, and lack of large shippers to diverse the shipping network. This study has academic and managerial implications in suggesting measures for facilitation of the Pohang Youngilman Port by amalgamating various viewpoints of governments and stakeholders, which can be used for policy development as well as practical solutions for the port.

To develop the port productivity and effictiveness, the introduction of the On Dock Operating System in Pusan Container Terminals has to be considered and the present Off Dock CY be closed step by step. This work aims to evaluate the needed CY area in Pusan Port under the On Dock Operating System. This researching flow is as follows. Firstly, estimate total sea-borne container cargo volumes in Korea and distribute them to all container terminals according to the past trends and the planned port development. Secondly, estimate the average period and the average tiers stored at On Dock CY in case of On Dock Operating System. Thirdly caculate the needed CY Area to handle the distributed container cargo volume under the On Dock Operating System. Finally, the following results are obtained. (1) In 1998, opening the Gamman Terminal, 827 thousands cubic meters are insufficient. (2) In $2001\sim2004$, the insufficiency of needed CY Area will be maximized and estimated to be 936 thousands cubic meters in 2001. (3) In $2005\sim2011$, opening the Gadu Terminal, the insufficiency of needed CY Area will be decreased and estimated to be 240 thousands cubic meters in 2011.
