Abstract
Because of the continuous increase in the demand for and importance of marine space, marine exploration and survey activities are being actively conducted in Korea actively. Because the marine survey vessels used for these activities have special operational patterns depending on the purpose and probe vessels, research on maritime traffic risk is required. In this study, an attempt was made to determine the correlation of each factor with the effect of marine exploration and survey vessel operation on maritime traffic. The status of ocean exploration and survey vessels in operation in Korea was identified, as well as the special operational conditions of some of the ocean physical probes. Generally, the number of exploration and survey vessels involved per hour, total vessel length(including exploration equipment), operation, interval distance of exploration as per plan, and marine traffic conditions(traffic volume and speed) can be classified as operating factors. To compare the results of the environmental stress, a maritime traffic flow simulation based on the "ES" Model was performed with each of the identified operating factors as independent variables. The results of the analysis confirmed that the environmental stress significantly changed in the order of traffic volume, ship length and speed. In addition, it was confirmed that the environmental stress is reduced when the operation course is set at an angle with the nearby maritime traffic flow. Accordingly, it can help reduce the operator's burden if the survey vessel operator understands nearby maritime traffic conditions and reflects them in the operation method when setting the operation plan.
해양공간 이용 수요와 중요도의 지속적인 증가에 따라 국내에서의 해양탐사 및 해양조사활동이 활발히 수행중이다. 이러한 활동을 위해 운항되는 해양탐사조사선은 목적 및 탐사선박에 따라 특수한 운항패턴을 가지므로 해상교통위험도를 고려한 연구가 필요하다. 본 연구에서는 해양탐사·조사선의 운항이 해상교통에 미치는 영향을 각 요인별 상관관계로 파악하고자 하였다. 우리나라에서 활동중인 해양탐사·조사선 현황을 파악하였고 일부 해양물리탐사선의 특수한 운항실태를 식별하였다. 운항자부담감의 결과를 비교하기 위해서 운항요인 중 각 2가지를 독립변수로하여 ES Model 기반의 해상교통류시뮬레이션을 수행하였다. 분석결과 교통량, 선박 길이, 속력 순으로 운항자 부담감이 두드러지게 변화하는 것을 확인하였다. 또한 인근 해상교통흐름과 선수방위(침로)가 거의 유사한 운항 침로를 설정할 경우 운항자 부담감이 다소 감소하는 것을 확인하였다. 이에 따라 해양탐사·조사선이 운항계획을 설정할 단계에서 인근 해상교통현황을 파악하여 운항방식에 반영한다면 운항자 부담감을 감소시키는데 기여할 것이다.
