우리나라에서는 최근 인천대교를 비롯하여 북항대교, 광양대교, 울산대교 등과 같이 항행로 상에 해상교량을 건설 중이거나 계획하고 있다. 그러나 이러한 해상교량 건설시에 정형화된 기준 및 법령이 미흡하여 해상교량 건설을 위한 사전 평가에 이해 관계자들이 합의를 하지 못하는 중 많은 시간과 경비를 낭비하고 있는 실정이다. 이 연구는 해운선진국 증 해상교량을 많이 건설하였고 건설 전 평가를 해 본 경험이 있는 일본의 관련 기준과 법령을 조사 분석하여 우리나라에 적절한 해상교량 건설 관련 기준 및 법령 작성에 도움을 주고자 한다.

SHS(Ship-Handling Simulator) is virtual generation of vessel traffic situation under various environmental conditions. Recent, with the introduction of MSA(Maritime Safety Audit), SHS is being used as a key facility to determine the safety of navigation. However, the current audit techniques specified in the implementation guidance of MSA have been prepared by generalizing common procedures and evaluation methods used by institutions operating simulator systems. Therefore, they need to be reviewed and supplemented. This study analyzed the adequacy of current audit techniques based on the limitations and problems, then suggested the advanced scheme of SHS such as standardization of ship models, standard manoeuvring and evaluation method. The results of this research will contribute to improving the quantification and reliability of audit techniques used in the MSA as well as upgrading of the simulator system.

The objective of this paper is to describe the result of development of collision avoidance supporting system, based on the electronic chart display and information system(ECDIS). In real ship operations, collision accidents happen frequently due to human errors such as the lax vigilance, misinterpretation of international regulations for preventing collisions at sea (COLREGs). We developed a system which will help to avoid these kind of accidents. This system can automatically recognize the risk of collisions, generate the safe alternative routes that comply with COLREGs, and then deliver the results into auto pilot. A virtual simulation assuming progressive collision situations revealed the usefulness of this system.

After forming a institutional framework with specified in Maritime Safety Law(ex. Maritime Traffic Safety Law) on May 27th, 2009, The efforts for improving 'Maritime Traffic Safety Assessment Scheme(MTSA scheme)' have continued to the present. But there's no review with the comprehensive and systematic approach for proceeding acceleration step of MTSA scheme. At this point, this study analyzed current status and derived improvement measures using by 'PIP'OU model' which was designed for the comprehensive analysis in accordance with metaevaluation theory, like as question investigation and etc. Consequently, it mainly needs to improve 'Assessment Plan' domain and minimized the difference in views between concerned parties. This study is expected to be used to develop systematic maritime policy by proposing the order of priority in improvement matters.

To assess the risk of marine traffic environments, with high confidential level, the risk factors comprising it should be identified and the risk acceptance criteria should be also provided. Furthermore, the relative importance of each risk factor(the weight of each risk factor on total risk) should be analyzed because the risk is expressed as the sum of risk factors comprising it. The twenty kinds of risk factors and its assessment criteria were suggested for the domestic marine traffic environments by an examination of the existing risk assessment models on the previous studies. The relative importance of each risk factor was also analyzed through the questionnaire using analytic hierarchy process by the marine traffic experts on the same studies. Based on these previous studies, the risk was evaluated at the port of Mokpo and its approaches on this study. The port of Mokpo and its approaches were divided into four sectors for the comparative evaluation, the result of the comparative evaluation on four sectors showed that the risk of the Jeongdeung-hae passage is the highest due to higher risk level of some risk factors(water movements, complexities, tug boats, pilotage, VTS) than the other sectors. The result of this evaluation is in accord with the analysis results of the other studies using various qualitative or quantitative risk analysis methods at the same sea areas.

항만법 제92조 및 항만법 시행령 제91조에 따라 항만관리에 관한 권한을 지방청 및 지자체에 위임하고 있으나, 연안항의 경우 관리주체인 지자체가 지역민들의 이해관계, 항만관리 인력 및 전문지식 부족 등에 따라 적극적인 항만관리를 수행하지 못하고 있는 형편이다. 본 연구에서는 해상교통안전진단 사례연구를 통해 우리나라 연안항 항만관리 실태와 문제점을 분석하고 제도개선 등 해결방안을 제시하였다.

During the years 2016 to 2020, the Ministry of Oceans and Fisheries embarked on a strategic initiative to develop a comprehensive Korean e-navigation system, which encompassed the establishment of an 'Long Term Evolution for Maritime (LTE-M).' The primary objectives were to proactively align with international navigation standards and enhance maritime safety for small vessels, particularly fishing boats. However, limitations were identified in the utilization of this network, primarily its constrained application for specific purposes. In response to these limitations, this study delves into user-centric investigations through surveys and interviews, with the goal of expanding the horizon of network utilization. User requirements emerged as the result of study, emphasizing the need for broader network applications, a wider range of target users, diverse network utilization methods, and regulatory streamlining. The user-driven insights gleaned from this study hold the potential to inform and shape future legislative measures, fostering more versatile and inclusive LTE-M network utilization for enhanced maritime safety.

This study aims to examine whether Marine sand mining business is Maritime Traffic Safety Audit and priority between Maritime Traffic Safety Audit and Sea Area Utilization Impact Assessment because development and action to use in the ocean is ambiguous, it is overlapped with system of environmental aspect, and priority is not designated. Therefore, the way to improve to settle the overlapping problem etc. between Maritime traffic Safety Audit and Sea Area Utilization Impact Assessment was suggested and legal ground for sand mining is suggested. Because management department for Maritime Safety Act and Marine Environment Management Act is Ministry of Oceans and Fisheries, the solution for this is both embodying co-experts on each committee for determinant of system with maintaining contact and radical revise of law. If revised, the possibility of accident in ocean is decreased, and it can be a way to protect marine environment.

The efforts for improving 'Maritime Traffic Safety Assessment Scheme(MTSA scheme)' have continued to the present since May 27th, 2009. But recently, there's a controversy about whether it has been performed properly or the results is significant. These new discussions were arose from lack of validity and appropriateness we had yet to find. At this point, it needs to establish sound MTSA scheme through the comprehensive review. This research developed a suitable meta-evaluation model for MSTA with applying theory of the teta-evaluation, that is the evaluation of evaluations and verified by using meta-evaluation methods like as literature studies, expert reviews, surveys and etc. The results of this study can be used to evaluate MTSA activities and it will contribute to improving MTSA scheme.

Intelligent maritime traffic information service for maritime traffic safety operates a service that provides safe and efficient optimal safety routes considering information such as water depth, maritime safety law, weather information, and fuel consumption. However, from a service user's point of view, they prefer a route that suits their personal navigation experience and style, such as unnecessary detours and conservative safety distances for maritime objects. In this study, the optimal safety route can be extracted based on the experience of service users without reflecting the separate maritime environment by adjusting the weight of the trunk line for the area where the ship frequently navigates with the ship's track data collected through LTE-M model was studied.
