Dangerous cargo in maritime transportation is increasing in international trade. The types and forms of dangerous cargo are very diverse, complex, and the scope is expanding widely. For this reason, it is increase risk of accident threatens the safety of ships and other cargoes, as well as serious damage. Carriers' require special care and handling of dangerous cargo and have a duty of care for safe transport. The shipper is obliged to notify the carrier of the nature and characteristics of the dangerous cargo prior to loading on the ship, the responsibility of the carrier varies depending on the notification or not. This study compares and analyzes the concept and classification of dangerous cargoes, the provisions of the Hague rules, Hamburg Rules and Rotterdam Rules about Carriers' Dangerous Cargo Liability Regulations, after reviewing case studies. We intend to provide information to dangerous cargo handling, the carrier.

This study is to improve the marine traffic environment along the west coast of the Korean peninsular so as to prevent the traffic accidents of the dangerous cargo carriers. The most used routes of the vessels were investigated from GICOMS database and the questionnaire survey. Gwanjanghang Sudo strait and Maenggol Sudo strait were considered to have some potential risks to the vessels. In this study, the alternative routes were developed to substitute the current routes near Gwanjanghang Sudo strait and the new boundary line of The Traffic Prohibited Area for Tanker was suggested to contain the Maenggol Sudo strait.

Marine casualties of dangerous cargo carriers lead to not only the loss of human life and properties, but also marine pollution caused by spilled oil and hazardous cargo. So the prevention of marine casualties and emergence response to minimize pollution are very important problems to be settled. But until now, most of salvage assistance jobs have been done based on rule of thumb without any technical support. It is not easy to cope with the incidents safely and rapidly under the current situation. The purpose of this paper is to develop a systematic and engineering salvage assistance tool available in the casualty sites. This paper contains the construction of salvage system, classification of technical items, and prototype system for the safety assessment. The developed system enable a salvage engineer in his/her salvaging jobs to perform safely and promptly.

IOn 7th of Dec. 2007, large oil spill took place the seas off the Taean coast caused by the collision between VLCC Hebei Spirit and crane floating barge Samsung-1 and a lot of problems were revealed during response to the accident. The author, accordingly, examined to analyze the cause of this accident on the aspect of spill prevention and presented some preventive measures, such as strictness to the current standard for tug operation, expansion of VTS service area and transfer of the VTS responsibility to Korea Coast Guard, designation of appropriate anchorage per ship's type, cargo and visiting purpose, and special management for dangerous goods carriers.

While major alliance container carriers in the post-corona era are enjoying the largest boom in history with their fleet reduction strategy, shippers companies are in a state of deteriorating import and export price competitiveness due to increased logistics costs, and forwarders who act for shipping companies' logistics services are also experiencing the burden of rising freight rates It is in a state of overheated competition and worsening profits for attracting shippers. For this purpose, research data, literature studies, statistical data and data from overseas specialized networks were used as prior research. Online surveys and telephone interviews were conducted, and as a result, four areas of cold chain (including perishable cargo), project logistics, UN procurement logistics, and dangerous goods logistics, which were found to be particularly in high demand, were analyzed to suggest entry strategies.

The Myodo-Strait at Yeosu Port is normally used as a major vessel passage for dangerous cargo carriers that carry regular products of dangerous goods. Currently, the Myodo-Strait allows only single passage, and the speed of passage is also limited to 8 knots. As a result, demurrage at the wharf of hazardous goods are also on the rise. It is expected that the development of a number of dangerous commodity wharf in the future will increase the volume of vessel traffic and increase the number of vessels used in the project area. Therefore, it is urgent to improve the waterway in order to secure the safety of ships using the waterway and improve the demurrage. This study proposed an improvement plan for the waterway through the analysis of the marine environment of the waterway and the process of collecting opinions from users in the sea area. and it was finally proposed to expend the width of the strait to 300m and secure a depth of 9.50m through Guidelines of Port and Harbor Design review and ship handling simulation evaluation. In addition it was evaluated that the vessel traffic congestions at peak-time in the situation of solo passage was greatly improved from 71.01% to 47.3% even when it was allowed to ship's crossing passage, as a result of vessel traffic congestions evaluation. According to the proposed improvement plan, the safety of ships' passage in the project area can be secured, and the issue of demurrage was also considered to be improved.

Korea has disposed of medium and low level radioactive waste generated by operating nuclear power plants permanently through the radioactive waste repository located in Gyeongju. However, the maritime transport of radioactive waste is exposed to the risk of marine accidents, and it will be necessary to introduce a system to secure safety from the viewpoint of the function and role of the Korea Coast Guard. Especially, Korea is affected by large-scale marine accidents, such as the Hebei Spirit or Sewol accidents. From this point of view, we analyzed the current status of Korea radioactive waste shipping and examined the response systems of major foreign countries. As a result of examining major cases of accidents, we have operated an Emergency Towing Vessel (ETV) fleet centering on European countries in order to respond urgently to marine casualties that may have social, regional and international effects, such as accidents of similar nuclear material carriers and dangerous cargo ships. It proves a partial effect. Based on this, we propose the introduction of the Korean ETV System. In other words, it is necessary to respond to large-scale marine accidents that could lead to enormous environmental, property, and personal damage, such as marine accidents involving nuclear material ships, large oil tankers, and large passenger ships. For this, it seems necessary to introduce Korea ETV, which can carry out emergency towing, oil pollution control function, large - scale rescue equipment and manpower. This will lead to the enhancement of the Korea Coast Guard response to marine accidents, and will not miss the golden time of the initial response to the national disaster, which will help protect precious people, property and the environment.

Natural environment, topographical conditions and marine traffic flows were investigated and questionnaire surveys were performed for the purpose of understanding the cause of marine accidents. The frequent cases of ships' dragging have happened at the anchorages of E-1, E-2 and E-3. The anchorage area is insufficient for the accommodation of a number of ships, the dolphins at the nearby piers are located near a narrow fairway. SBMs' are positioned too close to the fairway. It shows that many crossing marine traffic flows occur in all areas of the port. Marine casualties are concentrated mainly at No. 1 fairway, M1-M7 waters close to the dolphins and Gwanjeolgot, "E" anchorage and the waters close to the fairway "come and go" areas. The marine traffic flow is mainly caused by the ships' movement at the inter-port and most of the ships are the dangerous cargo carriers. And small ships like the tug-barge are moving disorderly in the ports. Furthermore, the fairway‘s layout is crossing each other. Questionnaire surveys of the users and experts shows that the LANBY that can distinguish the fairway of "come and go" ports is required.
