Abstract

National fishing harbour is as a refuge for fishing boats and a breakwater lighthouse is installed as a functional facility in consideration of harbour identification and the safety of passing vessels. In this study, the service level of breakwater lighthouse (234 units) was estimated based on the traffic volume of 105 national fishing harbour. For this purpose, the evaluation items were determined, the fishing harbour standard index was calculated (Fs=1), the proximity of fishing harbour was identified and the function (service level) of the breakwater lighthouse was estimated in the following order. However, national fishing harbour differed in size, traffic volume and fishing vessel capacity. Therefore, 105 national fishing harbour were divided into three groups through cluster analysis. The cluster analysis was based on the service level factors of the breakwater lighthouse, such as the number of weeding fishing vessels, tonnage of fishing vessels, the number of incoming and outgoing vessels per year, and fishing vessel capacity. As a result of the estimation, the service level of the breakwater lighthouse (light tower height, visual height, visual range, interval) was 10.50m, 16.50m, 7.00mile, 5.5sec for group 1, and 10.67m, 16.16m, 8.33mile, and 6.0sec for group 2, The three groups are 11.53m, 16.75m, 6.75mile and 5.0sec. The results of this study can be used as useful basic data for improving the service level of traffic vessels when a breakwater lighthouse is built in a fishing harbour in the future.

국가어항은 어선의 피항지로 운영되고 있고, 항구의 식별 및 통항선박의 안전 등을 고려하여 기능시설인 방파제등대가 설치되어 있다. 본 연구에서는 전국 105개 국가어항의 통항량을 기반으로 방파제등대(234기) 서비스수준을 추정하였다. 이를 위해 평가항목의 결정, 기준지수 산정(Fs=1), 근접항 식별, 방파제등대의 기능(서비스수준) 추정 순으로 진행하였다. 하지만 국가어항은 어항의 규모, 통항량, 어선 수용능력 등이 상이하였다. 따라서 105개의 국가어항은 군집분석을 통해 3개의 그룹으로 나누었다. 군집분석은 방파제등대의 서비스수준 요소인 제적어선 척수, 어선톤수, 연간 입출항척수, 어선 수용능력 등을 기준으로 하였다. 추정결과 방파제등대의 서비스수준(등탑의 높이, 등고, 광달거리, 등고)은 그룹1이 10.50m, 16.50m, 7.00mile, 5.5sec이고, 그룹2가 10.67m, 16.16m, 8.33mile, 6.0sec이며, 그룹3이 11.53m, 16.75m, 6.75mile, 5.0sec이다. 이러한 연구결과는 차후 어항에 방파제등대를 신설할 경우 통항선박의 서비스수준 향상을 위한 기초자료로 활용될 수 있을 것이다.
