"정박지"라 함은 기본적인 수역시설의 하나로 선박이 정박할 수 있는 장소로 선박들은 이곳에 투묘함으로써 법적, 물리적 보호를 받게 된다. 정박지는 해당 항만에 입 출항 대기 또는 작업대기 등의 목적을 위해 해당항만에서 지정 고시하여 운영하고 있다. 하지만, 마산항의 정박지의 경우 비상정박지를 제외하고는 흘수 6m이상의 선박이 투묘 대기할 수 있는 정박지가 부재하다. 이런 사정으로 현재 마산항 입항대기 선박 및 작업대기 선박들의 경우 지정된 정박지가 아닌 잠정 정박지와 관습적 정박지에 투묘대기하고 있는 실정이다. 이로 인해 선박 및 관제사 모두 법적, 물리적 보호를 받지 못하고 있다. 따라서 본 조사는 마산항의 현황파악을 통해 항만 운영, 관제운영 및 이용자 측면에서 마산항의 정박지 추가 필요성에 대한 내용을 검토하여 "마산항의 정박지 지정에 관한 연구"의 기초자료로 이용하고자 한다.

In the port of Ulsan with the area of harbor limit of $83km^2$, 25,432 vessels have been entering annually and only 35 vessels can anchor simultaneously at the anchorage. The area of harbor limit of Ulsan constitutes just 65 percent compared to $127.5km^2$ which is an average of main ports in Korea. In this regard, the port of Ulsan needs to expand the area of anchorages inevitably for enhancing the efficiency of port operation. To select the best anchorage area in Mipo harbor with the introduction of a concept of emergency anchorage, this study analyzed the safety of navigation and anchorage, and safety management, etc. in the prospected anchorage on the basis of the marine traffic survey observing traffic density. Furthermore, after drawing preliminary and final schemes through gathering the opinions from maritime users, safety management organizations and academic experts group, the best arrangement of emergency anchorage has been selected through the conference of interested parties. Then, the final scheme was also verified through figuring out the marine traffic system and carrying out the ship handling simulation.

해상교통혼잡도와 선박사고는 연관성이 높다. 이에 본 논문은 자본 등의 이유로 위기상황 대응에 취약한 소형 선박에 특정된 위험을 인식하고, 유사시 일부 선착장으로 선박이 집중되는 것을 방지하기 위한 시스템을 제안한다. 안드로이드 APP과 클라우드 서비스, 알고리즘을 통해 최적의 정박지 및 경로를 제공함으로써 소형 선박이 향후 위기상황에 효과적으로 대응할 수 있을 것으로 기대한다.

Jinhae Bay, characterized by frequent runaway ships and strong winds during typhoon attacks, poses a high risk of maritime accidents such as ship collisions and groundings. This study aims to determine a safe separation distance between ships in the Jinhae Bay anchorage, considering the unique environmental characteristics of the Korean sea area. Analysis revealed that an average of 100-200 ships anchor in the typhoon avoidance area in Jinhae Bay during typhoon attacks, with approximately 70% of ships experiencing anchor dragging owing to strong external forces exceeding 25 m/s wind speeds. In this study, we analyzed and presented the separation distances between ships during anchoring operations based on domestic and international design standards, separation distances between ships used as actual typhoon shelters in Jinhae Bay, and appropriate safe distances for ships drifting under strong external forces. The analysis indicated that considering the minimum criteria based on the design standards and emergency response time, a minimum safe distance of approximately 400-900 m was required. In cases where ample space was available, the separation distance was recommended to be set between 700 to 900 m. The findings of this study are anticipated to contribute to the development of guidelines for establishing safe separation distances between ships seeking refuge from typhoons in Jinhae Bay in the future.
