  • Present International trend of political and economical globalization plays a decisive role in or effect on the domestic problem between South and North Koreas. According to the timely historical tendency, economical cooperation or transportation between the two Korean regimes grows fast and the need of developing optimized logistics system grows significantly as well. In the present research, various transportation methods such as trucking, train, and short sea shipping(SSS) are surveyed and investigated. Based on the survey, a pusher-barge system, among various SSS systems, is introduced as the best or optimized transportation method between Incheon and Gaesugn.

  • Recently, the logistics industry in Asia is growing rapidly mostly with Chinese economic development. A variety of studies have been carried out to reduce the logistic cost under the situation that the global freight traffic continues to increasing. The Short Sea Shipping(SSS) system, a multi modal transport system centered around coastal shipping to realize high value-added logistics, achieved considerable success in EU. To implement the SSS system in Korea, it is necessary to develop the various essential technologies related to development of efficient ships and port facilities, including equipment for loading and unloading containers, operating and managing systems for freight terminals and technologies for tracking and securing containers. The present paper focuses on the survey of the current essential technologies available for implementation of the SSS system and suggests the direction of future development in the technologies.

  • Recently, a vessel's maneuvering performance is considered to be an important subject to secure safety at short sea shipping. Especially the high turning performance, which is required to avoid the marine pollution by the ships that was grounded, becomes more severe. In this paper, we discuss the effect of increasing rudder force on turning performance of short sea shipping ship by free running test in towing tank. First of all, we make the 47K PC model ship and high-lift rudder using Coanda effect. And we make the free running test system for the turning test in towing tank. And also we perform the turing test of 47K PC model in several changes of Coanda jet momentum and evaluate the turing performance such as advance and tactical diameter. Finally, we confirm that the increasing of rudder force is very effective to improvement of turning performance of short sea shipping ship.

  • This paper considers the problem of determining the cargo flow and the transportation mode in each trade route while satisfying the demand. Especially, the problem incorporates short sea shipping in Korea, which is becoming more important in order to improve efficiency of Logistics. The objective is to minimize the sum of shipping and inland transportation costs. To solve optimally the problem, this paper employs a linear programming model, which is an operations research technique for optimization. The problem is formulated by extending the well-known network design problem by considering capacity at seaport and limitation of total number of vehicles. The model is solved using CPLEX, a commercial linear program software. The test results using a real cargo flow data in Korea show that the model represents closely the real situation.

  • Recently, freight floe between south and north Korea is rising rapidly by increasing cf economical exchange between two Korea and growth of Gaeseoung Industrial Complex. Considering this trend of economic cooperation between two Korea, in addition to a land transportation route it is necessary to secure various logistics and transportation route. A barge transport system which has many merits such as a little initial investment and convenience of harbor loading/unloading has been also used to transport freight widely in the EU and USA. In this paper, firstly, a Gaeseoung industrial complex and its cargo transport are investigated and several candidate shipping routes which are using barge transportation system are proposed. And also we investigate a technical feasibility on a realistic possibility of shipping routes by some investigation activities. Finally, a suitable barge system of candidate shipping route(1) and(2) is proposed in this paper.

  • Recently, the transport quantity of goods between South and North Korea is rising rapidly by increasing of economical exchange between South and North Korea and growth of Gaeseoung industrial complex. In addition to a land transportation route, it is necessary to secure various logistics and transportation route for freight transportation between Incheon and Gaesung. In this paper, we investigated a construction of barge transportaion system between Incheon and Gaesung. The barge transportation system which has many merits such as a little initial investment and convenience of harbor loading/ unloading has been also used to transport freight widely in the EU and USA. Firstly, we investigated barge transport route, marine freight and barge fleet which consists of barge and pusher between Incheon and Gaesung. And next, we designed hull form and general arrangement of a barge and pusher based on shipping service condition, barge fleet, etc. Finally, a construction plans of barge transport system such as a operation of shipping service, berthing facilities, logistics center, intermodal transport are investigated.

  • The concern on the greenhouse gas emissions is increasing globally. Especially, the greenhouse gas emission from fisheries is an important issue from the Paris Climate Change Accord in 2015. Furthermore, the Korean government has a plan to reduce the GHG emissions as 4.8% compared to the BAU in fisheries until 2020. However, the investigation on the GHG emissions from Korean fisheries rarely carried out consistently. Therefore, the quantitative analysis of GHG emissions from Korean fishery industry is necessary as a first step to find a relevant way to reduce GHG emissions from fisheries. The purpose of this research is to investigate which degree of GHG emitted from the major offshore fisheries such as offshore gillnet fishery, offshore longline fishery, offshore jigging fishery and anchovy drag net fishery. Here, we calculated the GHG emissions from the fisheries using the Life Cycle Assessment method. The system boundary and input parameters for each process level are defined for the LCA analysis. The fuel use coefficients of the fisheries are also calculated according to the fuel type. The GHG emissions from sea activities by the fisheries will be dealt with. Furthermore, the GHG emissions for the unit weight of fishes are calculated with consideration to the different consuming areas as well. The results will be helpful to understand the circumstances of GHG emissions from Korean fisheries.
