This study introduces lessons learned from investigation and analysis of major domestic and overseas cases of marine chemical incidents involving hazardous and noxious substances (HNS) during maritime transportation by chemical tankers carrying petrochemical products in bulk. The study then suggests plans to improve domestic marine HNS training curricula based on these lessons. Lessons learned from six incident cases are classified into the following six categories: 1) incident-related information, 2) safety, 3) pollution, 4) response, 5) salvage and 6) others. Based on these six categories, it is suggested that the curriculum provided by the Marine Environment Research & Training Institute for marine pollution prevention managers aboard noxious liquid substance carriers should be changed from the existing two-day training of eight subjects (16 h) to a three-day training of sixteen subjects (24 h). In addition, it is proposed that the marine chemical incident response course of the Korea Coast Guard Academy should be changed from the existing five-day training of fifteen subjects (35 h) to a six-day training of thirty-two subjects (48 h). These results are expected to contribute to sharing experiences and lessons learned about response to marine chemical incidents and to be used as basic data for improving the education and training courses for response personnel in preparedness for marine HNS incidents.

Large and small marine accidents which are related to vessel's navigation are happening continuously and these maritime accidents have caused loss of lives and properties, and serious maritime environmental pollution damage. It is also true that maritime pollution damage is increasing due to these accidents, probability of growth of seaborne volume and complicated maritime traffic environment. Korea, recently, is developing an evaluation index which can assess sea risk through the evaluation of maritime traffic environment and provide danger and general information with relation to maritime traffic environment on target sea area to evaluate maritime traffic safety. In this paper, we intend to confirm the validity of maritime traffic safety on the basis of vessel navigator's risk consciousness and various sailing conditions by using the ship handling simulator. To confirm the validity of sailing vessel's maritime traffic safety, we use analysis of variance. By using analysis of variance, we analyze vessel navigator's characteristics, distance, speed and encounter type between vessels. Through multiple comparison of each factor's risk difference, we can confirm the change of numerical value of risk difference in statistical aspect.

The term "ordinary practice of seaman" is applied to hold the responsibility of those involved in marine accidents. However, there is a concern that the responsibilities of seamen may become unclear as the ordinary practices of the seamen are imposed. In addition, the responsibility for improvement is diluted by mentioning the ordinary practice of seaman when the navigation rules stipulated in the COLREGs is clearly violated. The maritime safety investigation and tribunal system thoroughly analyzes the causes of marine accidents to prevent the recurrence of similar accidents. As one cause that does not contribute to the prevention of the recurrence of similar accidents, it would be appropriate to exclude the term "ordinary practice of seaman" as far as possible. Accordingly, I reviewed the reason for the existence of the maritime safety investigation system and ways to improve the application of the term "ordinary practice of seaman," which is recognized as a customary and an unconventional navigation rule, by examining the theories on the ordinary practice of seaman and analyzing cases of court judgments and decisions in the Korea Maritime Safety Tribunal. I also proposed a modern interpretation on the responsibility for proper and purposeful application. In addition, from the viewpoint of preventing the recurrence of maritime accidents, it is suggested that the nounized term in Korea be replaced with the descriptive term.

Sunken vessels on major fairways can cause many problems in terms of maritime safety and the marine environment. In order to prevent secondary marine pollution accidents caused by sunken vessels, information on sunken vessels has been collected, a risk assessment has been conducted, and the relevant vessels are being managed according to the results of each assessment. However, there is still a demand for improvements. The most important of the improvement plans is a paradigm shift. In other words, the management of sunken vessels needs to be transformed according to a new paradigm to manage all sunken vessels within three years from the time of sinking. Legislative improvements are also needed for the reporting system for sunken vessels, risk assessment tools, the implementation of risk mitigation measures, and criteria for the implementation cost of risk mitigation measures. In addition, close coordination between marine pollution response and sunken vessel management efforts is needed. As the division of duties between the Korea Coast Guard and the Ministry of Oceans and Fisheries is vague, collaboration between the two ministries is required. Close collaboration is also needed between the departments of navigation safety management and sunken vessel management. Therefore, it is necessary to more clearly establish the relationship between the two systems and create a synergy effect between the two administrative operations using the results of the risk assessment in the Marine Environment Management Act to determine the navigational risk posed by obstacles with regard to the Maritime Safety Act.

Since many years ago and in spite of the existence of national regulations and international conventions ratified by the countries that are conformed the Central American Region (CAR), the seagoing maritime sector of this Region, has developed its activity without any type of safety measures. Therefore, a large number of people are known to die, disappear and suffer from serious injuries each year. These maritime casualties devastate the families affected by these events, and severely impact the local social and economic well-being. While all these accidents occurred in this Region, non government or any other official records are available recording these casualties Due to the lack of any historical written reports about maritime casualties occurred in this Region, the compilation of this type of accidents information and data was carried out directly by the researchers in the field. Also, all the information about the CAR Maritime Organization Components was too compiled by the authors from the respective National Maritimes Authorities. From the compiled information was elaborated the CAR maritime casualties data base and from the analysis of the above data base were determined the main causes of the maritime accidents occurred in the CAR. The lack of safety measures onboard and the ignorance of the presence and influence of atmospheric phenomena were among main factors that had been caused the maritime casualties in this Region. By other hand, from the analysis of the CAR maritime organization components, the existence of one level of organization very similar among them was determinate. The objective of this research was to analyze the role of the CAR maritime organization in the prevention of the occurrence of maritime casualties. The results of this study provides general understanding of the causes of this type of accidents in the CAR and basis for support in improving safety navigation system and measures so that the number of fatalities and maritime accidents may be reduced in the future.

This study proposed detection method of Marine debris using unmanned aerial photography. For unmanned aerial photography, a RC(Radio Control) helicopter which has good movability and economics was used. To a camera mounting, a gimbal equipment was attached to the bottom of the RC helicopter. The gimbal equipment is very useful because it is not seriously affected by vibration and rolling. In addition, we invented that digital image processing algorithm using Matlab program for detection of marine debris from photographs. Particularly, background subtraction in invented algorithm was applied. As a result, marine debris of a variety of forms from different sand states of coast were reliably detected. In the future, monitoring using proposed method was expected to contribute that the solution to representative problem of monitoring area selecting and estimate the total litter mass over the beach. Moreover, It is considered a greater application possibility to marine environmental observations.

The Korean Peninsula is surrounded on three sides by the East Sea, West Sea and South Sea which are connected to many rivers and streams, thereby facilitating easy inflow of debris from land. Furthermore, excessive debris inflow to the sea because of active fishing and various recreational activities. Debris entering the sea are weighted over time and settle in the seabed, thus, making direct monitoring of debris impossible and its collection difficult. Uncollected submerged marine debris affects the seabed ecosystem and water quality and can cause ghost fishing and ship accidents, especially due to waste net ropes and waste fishing gears. Therefore, understanding the debris distribution characteristics is necessary to assist quick collection of these debris (waste net ropes and waste fishing gears). Thus, this study conducted a survey of debris deposited in the seas of 39 ports. Furthermore, distribution characteristics and compositions of submerged marine debris were identified by a map prepared through GIS-based spatial analysis of the East Sea. Consequently, 58% of waste tires in the East Sea were concentrated in breakwaters and ship berthing facilities. Moreover, 26 % of waste plastics were distributed outside the port. Identifying the distinct distribution characteristics of submerged marine debris was difficult; however, compared with others, the distribution of waste plastics was possible outside the port. The findings of this study can serve as baseline data to assist the collection of submerged marine debris using the distribution characteristics.
