This study revealed practical implications by analyzing the clauses and disputable issues of the Korea Service Contract. Korea introduced Servcie Contract in the container part since Hanjin Shipping's bankrupcy and distributed the standard form(2019). After that, the standard form was revised during the supply chain crisis(2022). In the standard form, there are clause that require agreement due to conflicting interests of shipper and carrier. Therefore, the main clauses of the standard form were analyzed to derive the practical meaning to the both parties. In addition, in the process of introducing the standard form, the most disputable issues, liquidated damages and minimum quality commitment, were deeply analyzed to explain how shipper and carriers' benefit and loss differ as the clause changes. In conclusion, both parties must set LD at a very reasonable level so that they do not proceed separately with penalty. In addition, 'evenly' is a much more important than quantity for carrier in the establishment of MQC, so extra box option for shipper even during the peak season is needed to accommodate with service contract.

According to globalization of world economy by extension of production, sales and distribution all around the world and international transportation system changed into a transport system that puts great importance on speediness and value-added services, international transport system is changing into a Multimodal Transport Routing centered system that systematically connects marine, air and rail transports. Due to such changes production, sales and distribution must be provided in time and Multimodal Transport Routing, which can provide multi-dimensional logistics services to customers of global network, is needed but information connection for international transport and connection system between transport modes are insufficient and can not be activated. Especially in Korea, selection standard of 3rd party logistics companies and transport companies is presented, but logistics exclusive companies, which plan and execute the transportation, can't present a systematic evaluation standard for international Multimodal Transport Routing, selection. Thus, this research surveys important previous studies about Multimodal Transport Routing, selection, derives an evaluation standard for Multimodal Transport Routing, selection through interview with company officials, and presents a theoretical basis for Multimodal Transport Routing, selection through systematic analysis of Multimodal Transport Routing, selection using Analytical Hierarchy Process (AHP).

The offshore plant structure has been transported to the site by barge because it is hard to manufacture in site. When the structure was transported on the sea, offshore plant structures and connection were experienced repetitive submarine load. For this reason, it was known for that the axial force of high-strength bolted connection was declined. Therefore, in this study, high-strength bolted connection was evaluated the shear fatigue performance under longtime fatigue load during marine transport. The experimental variables were selected intial axial force, surface type, and bolt type because they ar important factors in the change of axial force of bolts. As a experimental results of considering various variables, the variation of axial force showed within 1%. Therefore, the high-strength bolted connection was verified structural safety under longtime fatigue load.

부산항에서 환적되어 일본으로 향하는 화물을 대상으로 각 일본항만까지의 해상운송에 지역별 JR(Japan Rail) 컨테이너센터까지의 내륙운송을 합한 이동경로와 비용에 관한 측면을 조사하여 이를 시나리오 분석을 이용하여 연구를 수행하였다. 일본을 네 개의 지역으로 나누어 일본의 항만을 큐슈, 동부, 중부, 관서지역으로 구분하였으며, 일본 주요대형항만과 중소형항만을 비교하여 효율적인 운송루트를 찾는 것에 중점을 두고 분석을 수행하였다.

해운물류를 통해 컨테이너 화물 운송에 소요되는 기간은 목적지에 따라서는 3개월 이상의 시간이 소요된다. 또한, 육상운송, 항만적치, 해상운송 등의 다양한 경로를 거치며 이동하며, 이때 필요로 하는 기능 또한 다양화 된다. 따라서 임베디드 장치를 이용한 해운물류 모니터링에서는 상황에 따라 사용해야할 통신방법과 센서 등이 달라지게 되며, 따라서 일반적인 배터리로는 화물 도착시까지 상태 모니터링의 라이프 타임을 보장 받을 수 없다. 본 논문에서는 해운물류의 흐름에 따라 필요한 통신모드 및 센서만을 사용하고, 배터리 관리를 통해 동작을 제어하는 방법을 제안한다 따라서, 다양한 통신 모드와 센서를 효율적으로 제어하고, 배터리 상태를 모니터링하고 관리함으로써 해운물류에서 화물의 출발부터 도착까지 라이프타임을 유지하여 지속적인 모니터링 정보를 제공할 수 있다.

최근 국제 운송에 큰 부분을 차지하는 해상운송에서의 오염물질 배출이 큰 논란이 되고 있다. 이 연구에서는 고속·대형의 컨테이너선, 크루즈, 여객선, 기타선 등이 기항하는 부산북항을 대상으로 선박의 배출물질을 계산하였다. 선박 대기오염물질 산정을 위해서는 선박의 활동 정보와 배출물질 계산에 활용할 선박 마력 정보가 필요하다. 먼저 AIS를 이용하여 선박 활동정보를 수집하고, 선박 마력은 선박 특성이 뚜렷한 컨테이너선과 탱커선의 제원을 DB화하여 추정하였다. 선박의 배출물질을 산정할 수 있는 추정 알고리즘을 개발하고 이를 이용하여 황산화물, 질소산화물, 입자상물질, 휘발성유기화합물의 배출물질을 계산한 결과 각각 48.3%, 42.5%, 5.4%, 3.8%의 비율로 산출되었다.

근래에 해상물동량의 증가로 선박에 의한 해상운송이 늘어나면서 우리나라 연안뿐만 아니라 전 세계 해상의 교통흐름을 복잡하게 만들었다. 특히, 주요 항만 인접해안, 협수로 및 주요 통항로는 더욱 복잡한 교통흐름을 보여주고 있다. 이에 어느때 보다 선박에 의한 해양사고 발생 가능성이 높아졌다. 이 연구에서는 해양사고가 생길 가능성이 가장 높은 해역에서의 원활한 교통흐름과 안전운항을 위해 우리나라 뿐만 아니라 전 세계적으로 설치 운용중인 VTS 시스템에 대해 고찰 하였다.

The maritime traffic analysis has been conducted in various ways to solve problems arising from the complex marine environment. However, recent trends in the maritime industry, such as the development of the maritime autonomous surface ships (MASS), suggest that maritime traf ic analysis needs change. Accordingly, based on the studies conducted over the past decade for improvements, automatic identification system (AIS) data is mainly used for maritime traffic analysis. Moreover, the use of geographic information that directly af ects ship operation is relatively insufficient. Therefore, this study presented a method of using a combination of shape format data and AIS data to enhance maritime traffic analysis in preparation for the commercialization of autonomous ships. Consequently, extractable marine traffic characteristics were presented when shape format data were used for marine traffic analysis. This is expected to be used for marine traffic analysis for the introduction of autonomous ships in the future.

This paper considers logistics decision support system which deals with transportation mode selection considering transportation and carbon emission cost. Transportation and carbon emission costs vary with the choice of transportation modes and to become competitive companies need to find proper transportation modes for their logistics services. However, due to the restricted capacity of transportation modes, it is difficult to balance transportation and carbon emission costs when designing logistics network including transportation mode choice for each service. Therefore this paper aims to analyze the trade-off relationship between transportation and carbon emission cost in mode selection of intermodal transportation and to provide optimal green logistics strategy. In this paper, the logistics decision support system is designed based on mixed integer programming model. To understand the trade-off relationship of transportation and carbon emission cost, the system is tested with various scenarios including transportation of containers between Seoul and Busan. The analysis results show that, even though sea transportation combined with trucking is competitive in carbon emission per unit distance travelled, the total cost of carbon emission and transportation for the sea transportation may not have competitive advantage over other transportation modes including rail and truck transportation modes. The sea-based intermodal logistics service may induce detours which have negative impacts on the overall carbon emission. The proposed logistics decision support system is expected to play key role in green logistics and supply chain management.

세계해운시장에서 그리스의 역할은 막중하다. 그리스 선주들이 직접 운항하는 선대는 많지 않지만 지배선단은 세계해운시장을 좌우할 정도로 그 규모가 크다. 세계 원유와 정유의 60%가 해상 운송되고 있는데, 그 중 25%가 그리스 유조선에 의해 운송되고 있을 정도이다. 그리스가 세계해운 1위국의 위치를 고수하는 저력은 어디서 나오는지, 그리스 해운산업의 현주소를 알아본다(편집자 주)
