새 정부는 국민의 행복실현을 위해 안전의 중요성을 강조하고 있다. 이에 해양수산부에서도 해양사고 30% 감소를 목표로 해양안전실천운동본부 발대식 및 해양안전헌장 선포, 선박안전관리자협의회 출범 등 민 관이 함께 해양에서의 안전 확보에 노력하고 있다. 그러나 안전관리의 주체인 해운선사의 안전관리 수준을 객관적으로 평가하기 위한 평가지표 및 안전관리 평가시스템 등은 없는 실정이다. 이에 본 연구에서는 도로, 철도, 항공 등 타 분야의 안전관리 정보시스템 구축 및 운영사례를 조사 분석하여 시사점을 도출하였다. 또한 해운선사의 안전관리 수준을 평가하기 위해 해양사고정보, 항만국통제 점검결과, 안전관리체제 심사결과 데이터를 분석하여 이들 데이터를 통합 관리할 수 있는 데이터베이스의 구축, 평가프로그램을 개발하였다. 본 연구에서 개발한 안전관리 평가시스템을 이용하여 해양안전 우수사업자 평가업무, 우수 선박관리사업자 인증업무 등에 활용할 수 있을 것으로 기대된다.

This report introduces a National Vessel Monitoring System(NVMS) within the General Information Center On Maritime Safety and Security(GICOMS) project and a national legislation system for ship's safety management in Korea. We also represent future directions of NVMS in terms of E-Navigation(E-Nav), which is the new study item for COMSAR and NAV that has been adopted from the Maritime Safety Committee(MSC) 81st session. It concludes the future E-Nav system, when it is built, that all functions of NVMS should be used by NVMS controllers as well as mariners, and we should also consider the existing NVMS infrastructure including S/W and H/W.

Recently, the outboard engine system of internal combustion engine is widely used in the field of small ship propulsion. However, the internal combustion engine has serious problems of energy depletion and environmental problems, so electric propulsion methods are being studied. In this paper, we have developed important motors and controllers of electric propulsion system for small marine outboard motors. The motor design was performed through the motor characteristics analysis method, and the 30Kw system was developed through the BEMF processing circuit and the power conversion circuit by the embedded microprocessor. This study was carried out through government supported projects and achieved quantitative targets through accredited institutions.

As around 100 hazardous substance loaded ships go in and come out of Yeo-su Port, Southern Coast, they cause and may probably cause small and large ship accidents in coming alongside the pier every year, so this study would research into a safety management system in case of ships coming alongside the pier.

To prepare the integrated safety management system 'e-navigation', research is being conducted on the route exchange for sharing intended routes between ship and ship, and between ship and land. But they don't have enough specific grounds for the effects of route exchange and the necessity of its introduction and focus on technical aspects like the implementation of route exchange. This study tried to quantitatively analyze the effects of route exchange on sailing safety with the use of ship handling simulation, integrate simulation performers' subjective evaluations, and investigate the effects of route exchange. The ship-to-ship route exchange resulted in the initial collision avoidance action time was 3.43 minutes faster, the collision avoidance direction change rate was 60 %, the proximity to target A was 31 %, and Mean Rudder Angle Index decreased by 57 %. In addition, 95 % of the survey respondents had an effect on the decision making of collision avoidance, 85 % had a positive impact on safety navigation, 90 % had an accident prevention effect, 70 % reduced the psychological burden of officers, and 70 % should be introduced in practice.

Shipbuilding and repairing enterprise has the characteristics of many hazards and accidents. Therefore, the safety management ability of shipbuilding and repairing MIS (management information system) must be effectively guaranteed. The verification on safety management is the necessary measure to ensure and improve the safety management ability of MIS. Safety verification can not only increase the safety of MIS, but also make early warning of potential risks in management to avoid the accidents. Based on the authoritative standards in the field of safety in shipbuilding and repairing enterprise, this paper applied modeling and verification method based on ontology to safety verification of MIS, extracted the concepts and associations from related safety standards to construct axiom set to support safety verification on MIS of shipbuilding and repairing enterprise. Then, this paper developed the corresponding safety ontology modeling and verification tool-SOMVT. By the application and comparison of two examples, this paper effectively verified the safety of MIS to prove the modeling method and the SOMVT can improve the safety of MIS in a much more effective and stable way to traditional manual analysis.

The Ship Safety Act prescribes matters necessary for the maintenance of seaworthiness and safe navigation of ships. In this regard, Article 10 of this Act requires shipowner to undergo occasional survey if he/she wants to temporarily change intends to modify the details entered in a ship survey certificate. Such measures are in accordance with the maintenance of the state of the ship after the ship inspection under Article 15 of this Act, and this Act includes "harbor construction work ship" under Article 39 Paragraph (1) of the Harbor Act. However, although the harbor construction work ship originally showed the same operating system as the barge, it was not applied to the Ship Safety Act and was registered and surveyed under the Construction Machinery Management Act. Then "Seokjeong No. 36" sinking accident in Ulsan on December 14, 2012, led to the amendment of the Harbor Act in 2016, and considering the fact that it was added to the Ship Safety Act and applied, there is a realistic limit to applying all the regulations stipulated in the Ship Safety Act to the harbor construction work ship. Accordingly, this study discusses the work characteristics through concept, registration, work area, survey regulations, application case of temporary alteration etc. of harbor construction work ships and controversial issues related to the scope of application of the Ship Safety Act of actual harbor construction work ships, and also the appropriate scope of "temporary alteration" among temporary inspections prescribed in Article 10 of the Ship Safety Act in consideration of the legislative purpose of incorporating harbor construction work ships into the survey subject to the Ship Safety Act in accordance with the revision of the Harbor Act.
