5개의 대기정박지로 지정되어 운영되고 있는 부산 남외항 정박지는 부산 북항과 감천항에 출입하는 선박과 수리, 기부속 및 선용품의 보급 등을 위하여 많은 선박들이 이용하고 있다. 그러나 현재 지정된 정박지의 수역은 양식장, 어장 및 저수심 구역이 포함되어 있기 때문에 정박선박의 좌초와 같은 해양사고의 위험이 높을 뿐만 아니라 예부선을 비롯한 소형선박들의 횡단 항해 등이 이루어지고 있어서 해양사고가 자주 발생하고 있는 실정이다. 이 연구는 남외항 정박지의 배치 현황을 분석하고 위험인자를 식별하여 이를 개선할 수 있는 방안을 제안하고자 하는 것이다.

The anchorage among harbour facilities should ensure sufficient water surface area for safe anchoring. A general method is to consider the L.O.A of the target ship and the depth and bottom quality of anchorage to calculate the water surface area of anchorage. However, the gross tonnage is used as a unit of the ship capacity standard of anchorage based on the detailed rules for harbour facilities operation in Korea. In this study, the gross tonnage is converted to L.O.A to calculate the actual anchoring radius of the target ship. This actual anchoring radius exceeds at 25 anchorages (among 90 anchorages) compared with the designated water surface area. Therefore, as an improvement plan of the ship capacity standard for anchorage, L.O.A should be used as a unit for anchorage based on the detailed rules for harbour facilities operation and related Korean maritime laws.

Now it is said that the insufficency of the designated anchorage for ships in approaching waters of Wan-do port is one of reasons for marine safety accidents, when they encounter rough weather near the port. This research examined geographical feature in approaching areas of Wan-do port and suggested appropriate mate weather anchorage. The situations of fishing nets were investigated Marine vessel traffic flow was also examined The optimal anchorage was suggested considering these results.

The purpose of this study is to obtain a safe area for a passing vessel between anchored vessels by developing a model to predict the collision risk, frequent collisions occur between the anchored vessel and the passing vessel through the anchorage. For this, this study selected the southern anchorage of Busan port, which is the largest harbor in Korea, as the target area and extracted and analyzed VTS (Vessel Traffic Service) data during the period in which anchored vessels were the most waited. The ratio of D/L for each bearing was obtained to determine the safe distance (D) passes based on the length (L) of the passing vessel between anchored vessels. Based on the average domain of the D/L ratio distribution, the percentage of anchored vessels within the scope of the pre-studied ship's domain was analyzed to obtain a domain reflecting the degree of risk of VTSOs. Further research will evaluate and analyze the collision risk of a passing vessel using Domain-watch, the minimum safe distance between anchored vessels, and the safe domain of a passing vessel through anchorage, to develop a model for VTS to manage anchorages more efficiently and safely.

Ulsan Port is in the situation which the harbour limit and anchorages are less narrow than other trading ports and the occurrence probability of marine accidents is high due to heavy marine traffic Especially, the shortage of anchorages will become worse in case that the number of inbound and outbound vessels increases according to the development of Ulsan New Port. We will find and suggest the plan to enlarge the harbour limit essentially needed to expand anchorages in this research The reasonable type of harbour limit which is based on the survey by a group of experts, was determined after the decision of the range of harbour limit to accommodate the relevant anchorages.

The purpose of this study is to estimate a proper Domain Watch between anchored vessels in order to propose a method for the efficient management of VTS(Vessel Traffic Service) of the N-anchorage in Busan harbor, which is the largest port in Korea. For this purpose, we proposed the calculation method of Domain Watch and investigated the ship length(L), the distance between anchored vessels ($D_{ij}$), the domain radius(R), and the domain radius vs L(R/L) during the peak time of the vessels in the latest usage of anchorage. As a result of technical analysis for the surveyed data, the minimum R/L for securing the safety distance between anchored vessels was selected based on 2.85 corresponding to the 70th percentile of the total data. This result was applied to the N-anchorage of Busan and compared with the 'Guidelines of Port and Harbor Design(2014)', and we have confirmed that it is reasonable to set the Domain radius with the minimum 2.85L or more in VTS. This study considers the safety management of anchorage for VTS. This study could contribute to the safety of vessels using anchorage and the safety management plan of VTS when it is applied to other ports in operation such as it was in Busan.

울산항처럼 정박지가 외해에 위치한 항만의 경우 기상예보도 없이 갑작스런 돌풍이 불게 되면 정박선들의 닻 끌림으로 인한 위험은 물론 정박지를 항해하는 선박들과의 충돌위험에 노출되게 된다. 본 논문에서는 돌발적인 기상악화로 정박지에서 발생하는 위험의 유형에 대해 살펴보고, 기상악화에 대한 사전 대비가 왜 어려운지에 대해 고찰하였다. 그에 대한 해결 방안으로 정박지에서의 선박들의 안전을 위한 해상교통관제센터의 돌풍 대비 운영 매뉴얼을 개정하는 방법을 제시하였다.

Based on the case of Busan Port November anchorage, which is a group anchorage, related regulations to promote group anchorage safety management, the turning radius of anchored ship, and more accurate weather information collection and safety through improvement of the supporting system for VTS operations to apply the anchorage location in accordance with reality that it is a suggestion for management improvement methods.
