The use of dual fuel (fuel oil and LNG) propulsion on seagoing ships is becoming increasingly common. Although LNG is not only solution, it can be regarded as the most competent solution that complies with emission rules in practical terms among gaseous fuels such as methanol, and ethane. Having a very low or no sulphur content, sulphur oxides in the exhaust gas are negligible. The limited space and frequent ship loading in small LNG-fueled ships make it difficult for satisfactory ship operation or management. In addition, ships operating in coastal channels rarely continuously navigate under the condition of a steady-speed in comparison to oceangoing vessels. Thus, crews in gas-fueled ships find it problematic to recognize the key elements to be taken into account such as the LNG fuel consumption during frequent engine power variations, accurate remains of LNG fuel, next bunkering time, and prediction of possible navigation time and distance. The LNG bunker for these ships is generally provided by a tank lorry at a specific terminal or bunkering shuttle. Therefore, it is necessary to estimate the appropriate bunkering time for stable operation if the bunkering facility is insufficient and the system has fluctuating load conditions for the fuel gas supply.
This study assessed the system stability, LNG fuel consumption, and dynamic response of the gas supply system under voyage conditions such as emergency operations for sudden load variation and maximum navigation distance without LNG bunkering.
