조류신호표지는 강한조류가 있는 항만입구나 항로페서 조류정보를 제공함으로 통항선박 안전에 중요한 역할을 한다. 우리나라는 서남해안은 일부지역에서 강한조류가 흘러 선박통항에 위험을 초래하고 이로인해 해양사고 위험성이 내포하고 있어, 선박통항의 안전을 위해 우리나라 연안에 조류신호표지 설치가 필요한 위치에 대한 타당성을 연구하고자 하였다.

Route Design & TSS(Traffic Separation Scheme} establishment are often used to improve the maritime traffic safety in the heavily congested traffic area. There are several domestic and international route design guidelines, but there is no guideline of TSS design As a result, TSS is usually designed based on the subjective opinions of professionals in this field. Until now, there exist a few papers dealing with the effects of TSS on the reduction of maritime accidents, however, it is hard to find a paper on the design guidelines of TSS. In this paper, TSS design guidelines are proposed based on the quantitative assessment of navigational difficulty felt by mariners, which is expected to improve navigational safety of vessels in congested area.

Route Design & TSS(Traffic Separation Scheme) establishment are often used to improve the marine traffic safety in the heavy waters. There are several domestic and international route design guidelines, but there is no guideline of TSS design. So, TSS is designed by specialist's subjective opinion. Until now, when TSS is designed there are a few paper about the easiness effectiveness of marine accident, but there is no paper to design TSS guideline. This paper proposes the design guideline about TSS to improve the safety of navigation vessel by the quantitative assessment in the viewpoint of mariner.

부산항대교는 부산 남구 감만동과 영도구 청학동을 잇는 총 길이 3,368m 규모의 국내 최장 강합성 사장교로 5월 22일 개통하였다. 특히 야간에는 경관조명 등 '빛의 연주'라는 주제로 화려한 볼거리를 구성하여 '부산 해상순환도로'를 활용한 새로운 관광명소로 운영할 계획이다. 그러나 부산북항 통항 선박의 경우 화려한 조명 및 부산항 배경광 등으로 인해 선박통항 시 위험성이 높아질 것으로 우려되며, 이번 연구를 통하여 부산항대교 경관조명에 따른 부산북항 도등 기능검토 및 부산북항 선박통항안전성에 관한 검토를 하고자 한다. 실선박을 이용한 현장조사를 통하여 현재 설계중인 부산항 도등의 기능을 재검토하고, 부산항대교 경관조명 및 부산북항 배경광에 따른 선박 통항 안전성을 검토한다.

The prevention of marine accidents has been a major topic in marine society and various policies and countermeasures have been developed, applied to the industries. The coastal VTS and navigational aids are considered a, one of the effective methods to promote marine safety but they need relatively huge amount of budgets to build. Thus prior to establishing these coastal VTS and navigational aids, it should be evaluated the navigational risk level in the coastal waterways from the Environmental Stress. So far as human beings are concerned, there are many types of fuzziness in the evaluation of navigational safety level. In order to reflect these fuzziness on this evaluation, this paper introduces the fuzzy integral suggested by Choquet to represent the fuzziness in the evaluation process. This paper aims to develop the method for this evaluation from the viewpoint of mariner's operational stress using the fuzzy logic and Choquet integral. In this paper, Korean coastal area is divided into 8 sectors and evaluated the priority for the needs of coastal VTS and navigational aids.

물동량 증가로 인하여 부산신항에는 극초대형 컨테이너 선박들이 입항하고 있으며 서컨테이너 부두 건설 사업이 완료되면 부산신항 진출입 항로 내 다양한 조우 상황 발생으로 충돌 위험 상황을 초래할 수 있어 선박 통항 안전성 향상 방안 마련을 위하여 부산신항 내 항만 입출항 현황과 해상교통흐름을 살펴보았으며, AHP 기법을 활용하여 위험요소 및 안전대책 식별로 도출된 안전대책을 기반으로 환경 스트레스 모델을 활용하여 해상교통류 시뮬레이션을 실시하여 각 안전대책의 교통 위험도를 파악하였다. 설문조사 및 시나리오 평가 결과, 선박운항자는 일방통행을 위한 진입금지 해역 설정을 가장 중요하게 생각하였으며, 이는 위험도 경감에 큰 효과가 있을 것으로 예상되었다, 본 연구는 부산신항을 입출항 하는 선박들의 통항 안전성 제고를 위한 안전대책 마련의 기반이 될 수 있을 것이다.

In these days, several bridges have been built or under construction over navigational channel in Korea In these cases there must be careful consideration for the marine safety of vessels to be passed by below the bridge. This paper aims to analyze the factors influencing maritime traffic safety and to figure out ample width of main span of these kinds of bridges through the reference study and FMSS.

해상교통안전성평가는 크게 해양 안전 및 환경측면에서, 세부적으로는 해당해역의 특성을 파악하여 항로수립, 해상교통안전진단 및 해상교통영향평가 등을 수행 하는 측면에서 중요하다. IWRAP은 IALA Waterway Risk Assessment라는 평가도구로 항만수로의 위험도(선박의 충돌 및 좌초확률)를 분석하는 정량적인 평가모델이다. 정량적인 해상안전 평가방법은 통항량, 선속, 길이, 선박의 통항분포로부터 해상에서 통항의 위험도를 평가하므로 인적, 지리적, 환경적 등 주관적인 요소들이 많은 정성적인 평가방법에 비해 적용이 간단하다. 본 연구에서는 IWRAP을 해상교통안전진단제도로의 활용을 위해 목포항 진입수로를 대상으로 IWRAP분석을 하여 그 실효성을 평가 하고자 한다.

Bridges across waterways act as interference factors, that reduce the navigable water area from the perspective of navigation safety. To analyze the safety navigational width of ships navigating bridges across waterways, the optimal traffic distribution based on AIS data was investigated, and ships were classified according to size through k-means clustering. As a result of the goodness-of-fit analysis of the clustered data, the lognormal distribution was found to be close to the optimal distribution for Incheon Bridge and Busan Harbor Bridge. Also, the normal distributions for Mokpo Bridge and Machang Bridge were analyzed. Based on the lognormal and normal distribution, the analysis results assumed that the safe passage range of the vessel was 95% of the confidence interval, As a result, regarding the Incheon Bridge, the difference between the normal distribution and the lognormal distribution was the largest, at 64m to 98m. The minimum difference was 10m, which was revealed for Machang Bridge. Accordingly, regarding Incheon Bridge, it was analyzed that it is more appropriate to present a safety width of traffic by assuming a lognormal distribution, rather than suggesting a safety navigation width by assuming a normal distribution. Regarding other bridges, it was analyzed that similar results could be obtained using any of the two distributions, because of the similarity in width between the normal and lognormal distributions. Based on the above results, it is judged that if a safe navigational range is presented, it will contribute to the safe operation of ships as well as the prevention of accidents.
