The goal of this study is to forecast the scales of seaborne trade of iron ore and coal. It is assumed that the seaborne trade of iron ore is the function of two independent variables(crude steel production, world GDP) and the seaborne trade of coal is the function of two independent variables(crude steel production, world electricity generation). The result shows that the regressions of two functions are statistically significant respectively. As the results of forecasting, the seaborne trade of iron ore in 2010 may be 892 million tons which is increased 5.1% compare to the level of 2009. Also the seaborne trade of coal in 2010 may be 827 million tons which is increased 6.1% compare to the level of 2009. In terms of the compound annual growth rate, it is forecasted that the iron ore may show 4.7% of increasing rate from 2009 to 2015 and the seaborne trade of coal may be increased 6.1% annually for the same period.

The aim of this paper is to make projection of the demand for export loaded container throughput originating at Incheon port in Korea over the period in question. Systematic analysis is used as a forecasting method instead of quantitative analysis. First of all, the method explores coincident indicators which may reflect the square measure of neighboring industrial complexes which originate/destinate general cargo in export traffic trends. It is noted that in terms of the export loaded container throughput, per unit production scale is intermediated transforming from square measure of production facilities to freight weight in Korea. Consequently, the future progress of the volume can be anticipated relying on the development schemes for developing square measure out of the total square of the industrial complexes. Thus, moving-into percentage of the industrial complexes, percentage of business categories, percentage of capacity and percentage of passing through via Incheon port are adopted and the future traffic demand is projected taking advantage of them.

항만의 개발은 투자시점에서 10여년이 소요되는 대규모 자본과 시간이 소요되는 사업이므로 항만 물동량을 사전에 정확히 예측하지 못하면, 과잉투자, 중복투자 또는 기관시설이 부족하는 등 큰 문제에 봉착하여 진다. 항만 물동량 예측은 항만 개발에 앞서 매우 중요한 과제이다. 따라서 본 논문에서는 파워심 프로그램을 활용한 항만 물동량 예측 시뮬레이터 개발에 앞서 기초 연구단계로 항만 물동량 발생 요소들의 관계를 정립하고 인과관계를 시스템 다이내믹스 기법을 이용하여 밝혔다. 이 시뮬레이터는 항만 물동량 예측 등 관련 산업기술 발전에 기여하리라 전망된다.

Pyeongtaek·Dangjin port handles the largest volume of finished vehicles in Korea, including more than 95% of imported cars. However, since the volume of imported cars has been stagnant since 2015, officials planning to invest in port development or automobile-related industries must make new forecasts. Economic variables such as the GDP often have been used in predicting automobile volume, but prior research showed that the impact of these economic variables on automobile volume I has been gradually decreasing in developed countries. These variables remain important predictors, however, in developing countries that experience rapid economic growth. In this study, predicting the volume of imported passenger cars at Pyeongtaek·Dangjin port, the decreasing Korean population was a major factor we considered. Our forecast showed that the volume of imported passenger cars at Pyeongtaek·Dangjin port will gradually decrease -by 2021. The Mean Absolute Percentage Error (MAPE) verification was performed to measure the accuracy of the predicted results, and the scenario analysis was performed on the share of imported passenger cars.

International logistics systems for cross-border trading aim not only to reduce costs and time, but also to maximize added value. For accuracy of shipping time, cost reduction, rapidity, and safety improvement, demand for Ro-Ro shipping as a global supply chain operating system has increased. To anticipate these demands, this study estimates the optimal demand and scale of Ro-Ro berth construction by analyzing shipping volumes between Korea and Japan. Based on Ro-Ro shipping speeds and distances between Korea and Japan, the shipping volume (container and general cargo) of Busan port is sorted into two separate zones. After analyzing the ratio of items that have great potential benefits from using Ro-Ro shipping, we estimate possible shipping volumes using Ro-Ro berth provision. The results reveal that two berths for 20,000t vessels are additionally required to accommodate the estimated volume. Results suggest the construction of an exclusive Ro-Ro berth in Busan port. This would not only accommodate the demand between Korea and Japan, but also provide a way to avoid the lean-to-one-side port policy.

The purpose of this paper is to construct the model that enables to estimate the amount of tanker voyage charter by region or by ship size. This paper decomposed the mechanism of voyage and time charter step by step, and apply the accumulated date of KMI chartering database. The results of the estimation is that the amount of voyage charter in 2007 will be 25,751 or 23.3% increase compared with that of 2000. And the amount of voyage charter in Korea will be 9.3% of the world amount, and will be 26.6% of the Far East amount.

Suez운하를 이용할 경우 부산항에서 로테르담항까지의 수송거리가 11,340마일이 북극해 항로를 이용할 경우 6,860마일로 36%가 줄고 수송기간도 10일 이상 단축되므로 북극해항로를 통한 유럽과 아시아간의 상업적인 수송이 이뤄진다면 해운회사들의 물류비용이 대폭 절감될 것으로 전망된다. 이런 시점에서 2011년 9월 한-러 국장급 해운회담이 열렸으며, 2011년 11월 23일 부산 누리마루 APEC House에서 "북극해항로 상업운항의 현황과 전망"이라는 주제로 국제세미나가 개최 되었다. 현재 북극해 항로를 통과한 선박이 2007년 2척, 2008년 3척, 2009년 4척, 2010년 10척이었던 것이 2011년에는 34척 총 82만톤의 통과 수송이 이뤄졌고, 러시아 북극내의 물동량은 2백20만톤에 달할 것으로 전망되었으며, 2012년의 통과 물동량은 100만톤을 상회 할 것으로 전망된다. 이에 북극해 항로에 대한 소개와 빙하지역을 항해하는 선박에 대한 운항지침에 대하여 검토해보고저 한다.
