The problem of the formation of boil-off gas (BOG) during the storage of liquefied natural gas on floating storage and regasification units is considered in this paper. The relevance of the study is due to the growing role of LNG infrastructure in the global energy sector, the need to increase the energy efficiency of cryogenic systems and reduce the load on auxiliary equipment. The purpose of the paper is calculation and analysis of the impact of reducing the heat input on the intensity of boil-off gas formation and the related operational and environmental indicators. Thermodynamic analysis, parametric comparison of calculation modes and assessment of the methane equivalent indicator are applied in this paper. The dependence between the thermal load on the reservoir, the amount of boil-off gas formed and the load on its processing systems has been established. The obtained results can be used for further modeling of thermal processes, improving liquefied natural gas storage systems and substantiating technical solutions for floating regasification complexes.
