For moving cargo between the North Pacific region and Northern European ports, the Northern Sea Route, along Russia's coastline, is 35-60％ shorter than the traditionally used routes through the Suez or Panama Canals. in addition to its shorter distance, there exist extensive ports und shipping infrastructure, and the potential for developing new markets in Russia and other northern countries including Korea and Japan. These incentives attracted considerable attention from the international shipping and shipbuilding industries and have formed a cooperative international research program, called as the International Northern Sea Route Programme (INSROP) This paper is a general compilation of the historical usage, recent trade developments, the physical environment, and the practical considerations that may shape future operational mode of shipping in the NSR based on results from INSROP reports. This study focuses mainly on an operation of commercial icebreaking cargo vessels that may be utilized along the NSR.

As the competition among ports emphasizes container cargo nowadays, it is essential for Incheon Port to respond wisely to the trend. But the timely establishment of basic logistics infra for the attraction of container cargo is delayed in comparison with rival ports; marketing activity is also depressed. Furthermore the understanding and the effort for the marketing of the institutions and businesses concerned with Incheon Port are less than sufficient. The marketing research for customers who are the basis and axis of marketing activities is almost wholly lacking. Things investigated by rival ports and external research institutions differ much in statistic according to the persons who cite them. As the study of port marketing is very theoretical and general, its application to reality is so much restricted. Therefore, this thesis considers ways for the main group of marketing to think and behave, from the viewpoint of shipping agents and the owners of cargo - the practical using group of Incheon Port. This thesis aims to deliver the systematic information and consistent view concerned with marketing.

The port, differently from general working place, is a closed area to execute security, customs, and quarantine procedures. The loading and unloading is being done differently by cargoes, ships, berths, and equipments. To load and unload a lot of equipments and different types of labor are required, in which work flow is very complicated. As above mentioned the port is very unique and deteriorated working place including danger. The purpose of this thesis is to propose ways to analyze and establish the preventive measure for cargo handling accidents in port. We have collected 923 accidents happened at Incheon Port during the period from 1994 to 2003. And to analyze and establish the preventive measure we have employed an advanced 6sigma DMAIC technology presently in spotlight as the best tool for management innovation. For the purpose of effective safety management of cargo handling in port, this thesis will help to revise and establish the law, system, standard, and standard working manual with respect to the port loading and unloading system. Now frequency of cargo handling accidents in port is highest for the second time among all industries, so we proposed the new safety management system to substitute port safety committee and to take full charge of safety in Ministry of Maritime Affairs and Fisheries.

Incheon Port has been served as not only the center of the Yellow Sea and port for trade with China but also domestic gateway port for the metropolitan area, playing a professional role as the greatest domestic Port which processes a variety of items such as imported raw materials, bulk cargo, oil and gas and so on. This study was conducted based on step by step business process between port entry and departure of ship, and incurred cost according to port industry classification and performance on the port facility. Bulk cargo and general cargo such as grain, food, steel, scrap metal, wood, coal, LNG, LPG and oil etc., which have a vast majority of import goods, have been treated by 57,062 thousand tons and 7,409 thousand tons of container cargo were processed at Incheon Port in 2009. Bulk vessels and carriers moving items such as LPG, LNG and oil recorded 38,836 thousand won and full-container vessels recorded 11,001 thousand won as the amount of notified port facility usage fees in 2008.

The double hull VLCC(Very Large Crude Oil Tanker) have been designed to have each four(4) longitudinal bulkheads and transverse bulkheads in general. Actually, the inside longitudinal bulkheads among four(4) longitudinal bulkheads, which are extended up to the end of the aft cargo hold for continuity of the members, have been designed with knuckled type inboard due to the narrowed hull shape at bottom region, but sometimes the straight type of longitudinal bulkheads were adopted based on the degree of the hull lines shape. However, regardless the type of longitudinal bulkheads, inside and outside longitudinal bulkheads conflict each other in aft cargo hold region This makes the structure more complex thus giving difficulties to structural design and production. Recently, a vessel of straight type was reported to have cracks on bracket end and tripping bracket toe in aft cargo hold region. As a solution to this problem, in designing the first 60m Beam VLCC, DSME developed a new cargo hold structure which is good in production and structural point of view by structural strength and fatigue analysis of fore and aft cargo hold.

해양플랜트는 일반 선박과는 달리 작업이 진행되면 고정된 위치에서 장시간 운용되는 특성으로 인하여 높은 신뢰성을 요구하고 있으며 안전 확보를 위하여 사용자 및 유지보수 작업자에게 센서 기반 상태 정보가 필요하다. 본 논문에서는 해양플랜트용 Cargo Lift에 대한 안전진단 및 점검을 위한 모니터링 시스템을 제안한다. 해양플랜트 Cargo Lift에 탑재된 센서부와 임베디드 시스템 계측부, 실시간 데이터 확인을 위한 모니터링부로 구성되며 조선해양 분야에서 장비들의 고도화 및 통합화에 따라 승강기에 대한 운행정보 및 센서 계측 정보의 교환을 위해 선박 표준 네트워크 IEC 61162-450을 기반으로 한다.

In this paper, one of the widely-used ice resistance prediction methods, introduced by Spencer(1992) of the Institute for Ocean Technology, Canada, is reviewed. Spencer's component-based scaling system for ship-ice model tests is analysed to estimate the ice resistance of various types of icebreaking vessels (Canadian MV Arctic, Terry Fox, R-Class icebreaker, US icebreakers Polar Star and Healy, Russian SA-15 cargo ships, Japanese PM Teshio and a model ship). The general form and the non-dimensional coefficients in ice resistance prediction formula are obtained using the published ice model test and full-scale sea trial data. The applicability of Spencer's method on R-Class icebreaker is discussed to estimate ice resistance for the larger icebreaking cargo vessels. Additional parameters to account for the difference in hull forms of icebreakers and cargo vessels are recommended to be included in the Spencer's original ice resistance prediction formula.

지금까지 일반화물의 항만하역능력은 수리적 모델을 기반으로 단순 계산하는 방법으로 산정되었다. 본 논문은 수리적 모델 기반의 계산 방법이 갖는 현실을 반영하지 못하는 한계점을 극복하고자 시뮬레이션 기법을 적용하였다. 항만에서 전용부두의 하역작업 사례로 적정 하역능력을 산정하기 위해 안벽 프로세스 규칙들을 반영한 선박 입항부터 출항까지 발생되는 프로세스를 모델링하였고, 프로토타입을 개발하여 시뮬레이션을 수행하였다. 묵호항의 실제 처리능력과 시뮬레이션 결과를 비교하였고, 시뮬레이션 프로토타입의 입력변수 조건을 반복적으로 실험함으로서 적정 능력을 산정할 수 있었다.

현재 국내에서는 물류시설의 부족, 물류시설의 비효율적 운영, 복잡한 유통구조, 물류산업의 낙후, 폐쇄적 정보 이용 등으로 인하여 필요 이상의 물류비용이 발생하고 있다. 이런 문제들을 해결하기 위해서는 물류구조의 전반적인 개선 및 물류시설의 확충 등이 필요하다. 하지만, 이러한 노력들이 기존의 원단위식 규모예측으로 이루어진다면 차량의 하역특성을 세밀히 고려하지 못하게 되고, 또한 향후 하역작업의 기계화 및 자동화 등으로 인한 작업능률의 향상을 반영하지 못 할 우려가 있다. 따라서 본 연구는 화물터미널에서의 화물차량의 이용현황을 기초로 대기행렬이론(queueing theory)을 적용함으로써 화물차량의 하역특성이 고려된 화물터미널의 최적규모산정법을 제시하였다. 또한, 현재의 하역시스템에서 이루어지는 작업들이 기계화 및 자동화, 정보화되었을 경우에는 화물터미널의 최적규모에 어떠한 영향을 미치는가에 대해 분석하였다. 분석결과, 하역시간의 규칙성 증가가 화물터미널의 규모변화에 미치는 영향은 크지 않은 것으로 나타났으며, 하역속도 및 서비스율의 향상은 화물터미널의 규모변화에 매우 큰 영향을 미치는 것으로 나타났다.

The ship structural design problem is formulated as a general nonlinear optimization problem with constraints. Characteristics of the general structural problems and various optimization techniques are discussed, with special emphasis on penalty function method for constrained problems. A simple example of the solution of a midship structure design of cargo vessel, which complies with the rules of the Korean Register of Shipping is shown using SUMT-exterior method with some search methods.
