세계적 선박 배출가스 저감에 대한 규제로 인해 항만 및 부두에서 육상전원공급장치(AMP, Alternative Marine Power)가 지속적으로 사용되고 있다. 국내 또한 항만 대기질 개선 특별법에 따라 AMP의 사용이 의무화되고 있고, 다양한 친환경선박과 연계하여 활용하도록 지속적인 시도를 하고 있다. 본 논문에서는 AMP를 통해 선내 전력을 공급하는 상황을 모델링 하여 AC Load Flow Analysis를 수행하였다. 이를 통해 선박에 전력이 공급될 때의 전기적 파라미터와 손실 등에 대해서 분석할 수 있다. 아울러 Transient Stability Analysis를 통해 계통의 사고 발생 시 선내 발전기를 통한 무정전전환에 대한 HSGT(High Speed Generation Transfer)의 한계값을 도출하고 이를 적용하였을 경우 결과에 대해 검토하였다.

Objectives: The successful implementation of the Port Safety Special Act is a very important matter. Now that one year has passed since its introduction, this study aims to review the achievements so far and identify future tasks. Methods: The provisions of the Special Act on Port Safety were analyzed and the latest literature related to port safety management was reviewed. In addition, an in-depth interview was conducted with a business owner. Results: The achievements over the past year are as follows. As business operators took greater responsibility for safety management, blind spots in safety were resolved to an extent. Specialized training for the port unloading industry was provided, and a safety management system was established for unloading docks. In addition, the Ministry of Oceans and Fisheries was able to intervene in the prevention of safety accidents at ports through the deployment of port safety inspectors. In 2022, the port industry accident frequency and death rate declined compared to the previous year. Conclusions: The "Port Safety Special Act" has become relatively well established in the port industry over the past year. However, since the Serious Disaster Punishment Act was implemented in January of the same year, there is a limit on determining what is necessarily the effect of the Special Act. Future tasks include unifying contracts centered on cargo handling companies, supporting safety management costs, increasing the number of port safety inspectors, producing reliable port disaster statistics, and cooperating between the Ministry of Oceans and Fisheries and the Ministry of Employment and Labor.
