Boil of Gas Formation Rate Analysis in LNG Storage Tank on LNG Fuelled Harbor Tug Vessel
Year: 2024
Type: conference-paper
Abstract: To accelerate the achievement of the net zero emission program which also one of the contributors of the climate resilience aspect in the Sustainable Development Goals (SDG), the use of natural gas as ship fuel is one solution during the energy source transition period. Storing natural gas in the liquid phase (LNG) can reduce tank volume requirements by up to 600 times compared to the gas phase. However, the formation of BOG (Boil of Gas) can increase the pressure in the tank. In this research, the rate of BOG formation in tanks designed for LNG storage on Harbor Tug vessels was analysed using the CFD (Computational Fluid Dynamics) method. The simulation results of the BOG formation rate when the ship is not operated and at full speed are 0.61 m3/minute, - 0.43 m3/minute, respectively. The storage tank is able to withstand gas pressure for up to 50 days when the ship’s system is not operated.
