  • Recently, the construction of Liquefied Natural Gas Carriers(LNGC) is being promoted larger and larger depending on long voyage. In 1950 years, $5,000m^3$ class of LNGC had been changed to $71,500m^3$ class in 1973. and to $210,000-266,000m^3$ class in 2007. Especially, the system of main engines and cargo control, Re-liquefaction of natural gases have become possible in LNGC. This research deals with the LNG projects, world markets of energy and developing tendency of liquefied natural gas carriers.

  • 최근 LNG 선박의 발주량이 급증함에 따라 LNG 선에 승무할 인력의 심각한 부족이 예상되고 있다. 이러한 LNG 선박에 승무할 인력 특히 고급 사관의 부족은 선박 자체의 안전뿐 아니라 궁극적으로는 LNG 수송체계의 안전에도 큰 영향을 미치게 될 것이다. 이 발표에서는 현재 전세계 상선대의 현황에서 출발하여, 최근 LNG 선박의 발주 현황, LNG 선박에 적용되는 최신 기술 및 엔진 등에 대하여 살펴 본 후에 전세계 LNG 선박 수주 잔량을 근거로 하여 필요 인력을 예측해 본다.

  • A risk assessment is performed at the initial design stage of LNG-fuelled ships subject to new fuel supply systems due to marine environmental and emissions regulations. Risk assessment involves a series of logical steps that enable systematic risk analysis and evaluation. LNG-fuelled ships mainly consist of a tank for storing LNG, a gas supply unit for supplying LNG to the engine, an engine using LNG as fuel, and a bunkering manifold for receiving LNG. The components of the LNG fuelled ship are determined according to the characteristics, size, rout, and operating distance. Therefore, the risk factors of each ships are different, and the risk analysis also changes. In this study we consider the systems of ships using LNG as a fuel and analyze the risk assessment of certain cases where the actual risk assessment has been carried out.
