Buoys are a necessary component for the safety of vessel traffic. However, if the buoy becomes inoperable from damage and loss, it can have significant impact on vessel traffic safety as well as unexpected budget spending. The purpose of this study was to evaluate the risk of accidental contact by applying the marine traffic assessment index that can reflect the traffic flow in the sea area. First, Busan Port No. 5 fairway, with a high number of buoys and many contact accidents, was set as the sea area for assessment. to investigate the status of accidental contact and evaluate risk of contact accidents based on the IALA Waterway Risk Assessment Programme (IWRAP MkII) and Potential Assessment of Risk Model (PARK Model). As a result, buoys are near the P recautionary Area wherein the traffic flow was complicated by the Masan port vessel and Busan new port vessel, and buoys are near the entrance of the Gadeok waterway, wherein vessels show a pattern of navigation across the fairway and buoys are near the breakwater in the inner fairway were considered as high risk for contact accidents. This study can be used as basic data for establishing an integrated model to evaluate the risk of buoy contact accidents.

선박과 선박간의 사고 위험도를 예측하는 교통정보 생성 기술을 해상교통관제센터에 적용하기에는 위험도 정보의 정확성에 한계가 있다. 또한 대상 해역에 대한 교통 패턴을 파악하는 밀집도 및 혼잡도와 같은 교통정보 생성 기술은 위험 우선순위 선박을 도출하는 것이 불가능하다. 복잡한 교통 패턴을 보이는 해상교통관제 해역에서 위험 선박을 인지하여 관제사의 관제 업무를 지원하기 위해서는 새로운 접근이 필요하다. 본 연구에서는 관제대상해역의 교통 상황을 총체적으로 파악하고 위험 선박을 사전에 인지할 수 있는 교통정보 생성을 위해서 기계학습 기법을 검토하였으며, 기존의 인공지능 한계를 극복하기 위한 딥러닝 프레임워크 도입을 검토하였다. 해상교통관제센터의 이미지, 메시지, 음성 등 다양한 형태의 연속적 자료들을 통합하고 이를 토대로 총체적인 분석을 통해 관제 업무를 지원할 수 있는 교통 상황 인지 정보를 생성할 수 있을 것으로 파악되었다. 빅데이터 기반의 기계학습은 보다 의미 있는 상황 인지 정보를 생성할 수 있기 때문에 이를 위한 관제 센터의 각종 데이터 통합이 필요하다.

Since July 2006, marine traffic safety management system have been enforced to support the vessels transiting across the coastal area and the vessels coming in and out of ports in southwestern coastal area where heavy traffic density and marine casualties occurred frequently. The marine traffic volume for the marine traffic environmental assessment was measured by the information from RADAR and AIS system in the area. The distributions of marine casualties were analyzed in the main routes and traffic separation schemes during the last five years and the navigational dangerous elements were investigated with the influence of natural environment, the distribution of fisheries and survey questionnaire. Marine accidents of merchant ships have a tendency to decrease gradually but in case of fishing boats, the rate of marine accidents have a contrary results in this area during the last five years. The dangerous elements on navigation appeared to be the dense force from June to August, fisheries activities and the vessels which not follow the compulsory watch on VHF-band radio communication equipments.

해상 교통 환경은 해운 산업이 발전함에 따라 더욱 복잡해지고 다양화되었다. 이에 따라 해상 교통 관제를 시행하는 선박교통관제사 업무의 중요성이 높아졌으며, 효율적인 교통 관제 시스템 지원을 위한 새롭고 다양한 시도들이 이루어지고 있다. 그러나 현재 선박교통관제에 관한 법률에서는 선박교통관제사의 업무에 대해 해양수산부령으로서 항만운영정보시스템에의 자료 입력을 규정하고 있으며, 이는 교통환경 파악 및 교통 관제에 집중하여야 하는 관제사에게 주의력 상실 등 비효율적인 관제 업무를 초래할 수 있다. 따라서 본 연구는 가장 입출항 선박이 많고 해양사고가 많이 발생하였던 부산항 VTS 센터의 관제사를 대상으로 시선측정실험을 실시하여 실제 관제 업무 시 관제 일지가 차지하는 비율을 확인하고자 하였다.

The representative risk evaluation techniques of the marine traffic environment are the FSA, PAWSA, & IWRAP. For the development of these techniques, the risk factors suitable to the marine traffic environment should be selected & the assessment criterion of the risk factors should be provided. The risk factors were selected as the factors that relate both to the frequency of casualty & to the consequence of casualty because the risk was defined as the frequency of casualty times the consequence of that casualty on the existing techniques. But, the risk factors relate to the consequence of casualty are excluded because the risk is defined as the sum of the risk factors including the frequency and the consequence by factors on this study. The 20 kinds of risk factors to compose the risk are selected and classified into 5 categories according to similar nature through the analysis of preceding study on the classification of the risk factors. Finally, as the foundation of risk assessment model's development for domestic marine traffic environment, the practical assessment criterion of the risk factors are suggested.

해상교통관제 업무는 선박사고 발생 위험에 대한 부담감 및 교대근무 등 불규칙한 근무형태로 인해 스트레스가 많은 직종이다. 특히나 관제 업무는 고도의 주의와 예측능력을 요구하는 업무로 이를 저해하는 인적요인 분석 및 관리 필요성이 절실한 분야지만 관제사의 직무스트레스에 관한 연구가 전무한 실정이다. 관제사의 스트레스로 인한 피로증상은 관제업무수행에 필요한 인지능력이나 의사결정 능력을 저하시킬 수 있고 이로 인해 업무수행에 차질을 빚을 경우 안전사고로 이어질 수 있는 위험이 존재한다. 그러므로 안전과 직결된 관제사의 스트레스는 과학적으로 연구되어야 하며 제도적 마련과 더불어 체계적 관리가 필요할 것이다. 이에 본 연구에서는 한국인 직무스트레스 측정도구를 이용하여 관제사의 직무 스트레스 수준을 파악하고 직무스트레스 관리의 필요성에 대하여 제고해보고자 한다.

통영연안VTS 관제구역은 남해 주요 항만으로 가기 위한 중요 길목으로서 일평균 700 척의 선박이 이용하고 있다. 최근 3년간 통계 자료에 따르면, 관할 해역 전체 해양사고 중 내항 어선과 관련된 사고가 약 70 퍼센트를 차지하고 있다. 최근 해상교통환경이 복잡해짐에 따라 비관제대상인 내항 어선의 민원이 증가하고 있으며, 안전관리를 위한 대책 마련의 목소리가 높아지고 있다. 이에 제도적, 기술적 개선 방안을 중심으로 해상교통안전 증진 방안을 살펴보았다.

Natural environment, topographical conditions and marine traffic flows were investigated and questionnaire surveys were performed for the purpose of understanding the cause of marine accidents. The frequent cases of ships' dragging have happened at the anchorages of E-1, E-2 and E-3. The anchorage area is insufficient for the accommodation of a number of ships, the dolphins at the nearby piers are located near a narrow fairway. SBMs' are positioned too close to the fairway. It shows that many crossing marine traffic flows occur in all areas of the port. Marine casualties are concentrated mainly at No. 1 fairway, M1-M7 waters close to the dolphins and Gwanjeolgot, "E" anchorage and the waters close to the fairway "come and go" areas. The marine traffic flow is mainly caused by the ships' movement at the inter-port and most of the ships are the dangerous cargo carriers. And small ships like the tug-barge are moving disorderly in the ports. Furthermore, the fairway‘s layout is crossing each other. Questionnaire surveys of the users and experts shows that the LANBY that can distinguish the fairway of "come and go" ports is required.

To prevent serious maritime accident and eliminate the cause of the potential maritime accidents, Maritime Safety Audit Scheme was formally institutionalized through amendment of Maritime Traffic Safety Act(May 27, '09). At the initial step of the enforcement of the law, it has risen the necessity of amending the present institution concerning with the range of applicable business, method of practice, detailed technical standards in the assessment articles, etc. Among them, the assessment of marine traffic congestion has been practiced as a mandatory assessment article, but it is analyzed that the assessment doesn't reflect current variation of ships' size and its speed. By analyzing the status of assessments on marine traffic congestion so far and collecting experts' opinion, this paper suggests draft amendments to improve technical standards on the assessment of marine traffic congestion.
