This paper considered the concept and characteristic OSV operation business for support the offshore plant and suggested amendment Maritime Transportation Laws, legislative proposals to solve the legal absence and to develop offshore service industry. Because Maritime Transportation Laws specialized for the carriage of passenger and goods by sea is not perfectly covered with Offshore support business in Korea. So it is necessary to make an explicit amendments for the article of Maritime Transportation Laws that founds absence of the law with the definition of terms to correspond related existed regulation reflected on the characteristic offshore support business by using OSV to develop offshore plant industry including support, service, supply, transportation etc. I expect that this paper will be a basic study to make a government policy, law, regulation to activate Offshore Service Industry in the future.

Recently, a logistics between south and north Korea is rising rapidly by increasing of 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 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 social and economical feasibility study is performed about a shipping route which is using barge transportation system between Incheon and Gaesung. And also we propose several candidate shipping route and investigate a technical feasibility on a realistic possibility of shipping service by some investigation activities. Finally, the optimized shipping route and barge transportation system are proposed in this paper.

Marine ships have played an important role as a carrier, transporting much more than 80% of all international trading, and marine transportation is an internationally competitive, strategic, and great national important industry. However, those marine ships have the characteristics such as voyage of long distance, large-volume and lower speed than the other carry system. Therefore, it is important to manufacture a larger and faster ship, however, the steel plates which are consisted with most of those ships has brought about many corrosion problems in sea water such as general corrosion, localized corrosion, cavitation and erosion corrosion etc.. Most hulls of the ships have been protected with paintings, sacrificial anode, marine growth prevention system, and impressed current cathodic protection methods against numerious corrosion problems mentioned above. However, these conventional methods are not very effective because the rudder of ships stern are exposed to very severe corrosive environment such as tides, speeds of ships, cavitations and erosion corrosion, etc.. In this study, electrochemical and cavitation characteristics was investigated for the rudder material of ship which is exposed to serious corrosive environment. As a result, it is considered that the optimum cathodic protection potentials of rudder material is the range of -0.6 V ~ -0.8 V(Ag/AgCl) in static seawater.

With international urgence of terror situation, many methods of terror techniques and skills are appearing and more intense and threatening terror is braking out not only in the air(plane), but also in the sea(ship). Korea is surrounded by 3 sides of sea and is a proud maritime nation that should advance to foreign country through the sea because South Korea and North Korea are confronting. Korea depend on the maritime transportation, 99.7% of exporting, importing material resources. Therefore, acquisition of the marine safety has the great affect on national security and economical life. On the high tension of situation about threat and possibility of maritime terroism, the potential ways of the improvement policy for counter-tactics against big maritime terror are the following. First, we should construct clear and well-organized network for accurate information about maritime terrorism Second, we should have the information of all domestic, foreign passenger's ships Third, national important facilities such as atomic energy plant, thermo-electric power plant, shipyard need policies to manage all emergency situation Fourth, government authorities should improve tactic abilitities by competing with support and budget inside of nation as well as outside of nation. To develop big maritime terror of our country, we will have to hold cooperative training & tactics contest of big maritime terror by cooperating educational industry organization with similar institute, improve the ability of members of big terror and acquire tactics information by excavating and exchanging a new technique through tactics seminar and public hearing.

The positive and negative opinion to cargo demand of Incheon's SAMT in the near future remains cloudy. Considering port and shipping environmental changes and the logistics situation of China which explains the lack of facilities in Chinese airports, the creating of SAMT cargoes of the Incheon region could catches a favorable opportunity to be a logistics hub in the North-East Asia. On the other hand, as open-sky policy and direct-call service has been carried out between China and N.A.(North America), Incheon could cause a loss of competitiveness in SAMT because the enhancement in the aspect of the connectivity of Chinese airlines and shipping lines makes customer sent to last destination their cargoes whenever they want. In the same context, this paper analyses on conditions of domestic and international SAMT and proposes in this uncertainty future forecasting of SAMT of Incheon by scenario planning according to changes in integrated SAMT, measuring the likelihood of final scenario. This study shows the Sea & Air multi-transport volume will have either slight increase or decrease from the current condition. Consequently, RFS expansion and system & service improvement through strong ties with major cities in China will be required in a short run aspect. Nonetheless, we also need to take domestic & international transportation environment into account in the long run.

This paper describes the development of moving watched chamber. For the most part, the watched chamber have been located in the inner-bay. But, there are many problems of sea-water pollution. Therefore, the watched chamber must be relocated to undeveloped coastal area. The watched chamber which is located in the bay has a bit of damage by bad weather. But, the moving watched chamber would be exposed to bad water. It is desirable to improve the system of chamber. If we make a good design of the moving watched chamber with studying of waves and hydrodynamics, it would be possible to culture fish at the coastal sea area. When a fixed system is changed into a movable one, we can obtain the following advantages: 1. The possibility of diminishing the sea water pollution, easying the overcrowded state in a inner-bay farm, and relieved of limitation caused by bad conditions such as waves, red tides and terrains. 2. It would be easy not only to move the watched chamber system in accordance with weather conditions or occurrence of red tides, but also to select good sites for watched chamber fishes. 3. Transportation and good supervision with the automated design system can results with the effectiveness which increases the amount of aquatic products.
