  • 본 논문에서는 수중 초음파 전송을 이용하여 해양 사고 발생 시 수중 실종자의 신원과 위치를 파악할 수 있는 재난 대응 시스템을 제안한다. 실종자 몸에 부착된 초음파 발생기에서 나온 신호를 해상에 배치된 다수의 하이드로폰 센서 노드에서 감지, 분석해 저전력 통신으로 선박 등에 설치된 중앙 제어시스템에 보내면 이를 분석해 실종자의 위치 등을 판별할 수 있어 수색 작업에 큰 도움이 될 것으로 기대된다.

  • 해상 사고 시 지상에서 통상적으로 사용하는 빛이나 전파가 투과하지 못하는 수중에서 수중 음향을 이용해 수백 m 이상의 원거리에서 실종자나 화물의 위치를 추적하기 위해 요구되는 조건들을 분석하고 이를 실증하기 위해 인체에 부착 가능한 크기의 소형 수중 음향 송신기와 이를 찾기 위해 수색 작전에 사용하는 수신기가 제작됐다. 이를 사용해 서해 상에서 1km 거리에서 음향 신호 수신을 확인했고 실제 현장에서 적용되기 위해 필요한 개선점들을 정리했다.

  • This paper reviewed the diving standards for underwater work in hostile environment and analyzed applied Navy diving technique, diving equipments and procedure for rescue operation of Navy ship Cheonan's missing crew occurred near Bak Ryung Do in March 2010. The operation was done beyond the international standards and safety practice, and by considering the nature of the mission, urgency and effectiveness as well as the detailed facts such as duration and depth of the dive, type of work to be performed, environmental conditions, time constraints of early rescue operation, it is analyzed that using air scuba diving system was adequate.

  • In general, life jackets are worn by people in critical situations on the water to rise to the surface without falling into water, and life jackets simply serve to prevent sinking, but do not actively help rescue disaster areas in critical situations early. In order to solve this problem, a device that automatically generates a distress signal in an emergency situation was developed. When the survivor is in hand for a while, the distress signal generator is automatically separated from the life jacket, allowing information such as location values and other information to be transmitted wirelessly and a rescue signal using LED light. As a result of the experiment, when submerged in water, the life jacket and the distress signal generator were automatically separated, and the result of wireless transmission of the coordinate value of the location received by the GPS was confirmed. By using this, the location of the distress or missing person can be identified, which can be quickly replaced in case of an emergency

  • This study examines the efficiency of safety management measures taken in coastal waters to prevent coastal accidents. Recent years have witnessed about 800 cases of large and small coastal accidents in coastal waters annually. On average, these accidents have been responsible for 129 deaths annually, Thus, there is a need for effective preventive measures. Accordingly, the Korea Coast Guard enacted the Coastal Accident Prevention Act in 2014 and has cooperated with related organizations, such as local governments and the Ministry of Oceans and Fisheries, to safely manage coastal waters. However, compared to the rapid increase in human coastal activities, coastal accidents continue to occur due to the lack of a safety mindset among the Korea Coast Guard, a lack of public safety awareness, a lack of safety management facilities, and poor interest from related organizations, among others. This study examines the conditions and problems faced with regard to safety management in coastal waters based on recent coastal accident data, and analyzes foreign coastal waters safety management cases. Various methods to improve the safety management efficiency in coastal waters are proposed, such as enhancing the safety mindset and capabilities of the Korea Coast Guard, strengthening cooperation among related organizations, increasing the role of local governments, expanding and strengthening safety management facilities by applying new technologies, inculcating a culture of maritime safety, and activating private-public collaborative governance.
