Liquefied natural gas has started to establish itself as the fuel of choice across the globe, evident from its sustained growth over the last three decades. As a result, more regasification terminals are coming up every year. Hence, it is critical to develop technologies which make sure the plants are operated efficiently. This paper studies the generation and management of Boil Off Gases (BOG) in LNG regasification terminals. The effect of time varying ambient temperature on the BOG generation is studied, and ways to improve the operational efficiency of BOG compressors are suggested. © 2019 Elsevier B.V.
