Quantitative Risk Assessment of Fsru and Connected Infrastructures in Harbour Area. A Comprehensive Applicative Experience from Early Design to Plant Operation

Abstract

Liquefied Natural Gas (LNG) is considered a prominent and strategic energy source to meet the growing demand within the current pathway towards EU decarbonization of the energy and transport sectors. This paper outlines the risk analysis approach developed within the preliminary and final design phase of an FSRU in an Italian harbor area, including technological solutions ad-hoc developed to prevent, minimize and manage environmental and accident risk. The process safety risks associated with side-by-side operations of LNG transfer from the carrier, the regassification process and the transfer to the national transfer infrastructure are thoroughly analyzed and faced by evaluating relevant scenarios and designing the connection infrastructures.
