LNG 연료공급 시스템 Skid 배관구조 진동 안정성 평가

초록

Following the International Maritime Organization (IMO) regulations on ship emission reductions, LNG fuel propulsion systems have gained attention as an alternative in the shipping industry, making the LNG fuel supply system an important component. When LNG is used as fuel, it must be converted to natural gas, a process involving high-temperature and high-pressure fluids that requires stability evaluation. In this study, the vibration stability of the LNG fuel supply system skid piping structure was evaluated by considering potential excitation sources, and vibration analysis was performed to identify natural frequencies, mode shapes, and weaknesses of system. Frequency response analysis was conducted to assess resonance possibility, and response spectrum analysis was used to evaluate the structural stability against damage.
