Although marine structures are a risk factor interfering with the passage of ships, there are no obvious guidelines on the required safety distance between ships and marine structures under regulations and laws. In this study, the width of the shipping route width was set based on the AIS data to analyze the separation distance between marine structures and ships, and the ships were classified by the length of each ship. By analyzing the distribution at marine structures, this study confirmed that the ships' traffic volume was in the form of normal distribution. To statistically analyze the separation distance between the traffic distribution results and the normal distribution of ships in this study, the traffic pattern analysis around the marine structures was performed. As a result, the traffic pattern was different by length and the recommended safety distance for each length is presented accordingly. Referring to the IMO (International Maritime Organization) the standard turning circle and reference of safety separation distance between ships and offshore wind turbines of the CESMA (Confederation of European Shipmasters' Associations) and P IANC (World Association for Waterborne Transport Infrastructures), the analysis was conducted on ships that did not follow the set distance among the AIS data by setting the distance within the recommended ship safety distance to 5-7 overall length. As a result, the 5.5 length over all of the safety recommendations were selected as appropriate, and based on the above results, the two cases recommending ship safety distance were proposed.

국내 해상풍력발전단지가 증가함에 따라 소형선박의 단지 내 위험통항이 증가하고 있으며, 제한된 시계 또는 야간항해 시 해양풍려발전단지 부근을 항해하는 선박들의 안전항행 우도 및 해양풍력단지 시설물 보호의 필요성이 높아지는 등 해상풍력발전단지 내 항로표지가 중요한 의미를 갖게 되었다. 이 연구에서는 국제항로표지협회의 권고안과 주요국가의 국내규정 그리고 국내관련 규정을 비교·분석하여 항로표지의 기능 및 규격에 관한 기준의 개정방안을 제시하였다.
