This document gives guidelines for the design, construction and operation of all onshore liquefied natural gas (LNG) installations for the liquefaction, storage, vaporization, transfer and handling of LNG and natural gas (NG). These requirements can be applied to bio methane and synthetic natural gas (SNG) accordingly. This document is valid for plants with LNG storage at a capacity above 200 t. The designated boundary limits are LNG inlet/outlet by the ship’s manifold including vapour return connection, the truck loading /unloading connection including vapour return, the rail loading/unloading connection including vapour return and the natural gas in and outlet boundary by piping systems. Terminals or plant types have one or more boundary limits as described in this scope (see Figure 1). A short description of each of these installations is given in Annex G. Feed gas for LNG liquefaction installations (plant) can be from gas field, associated gas from oil field, piped gas from transportation grid or from renewables. Floating solutions (for example FPSO, FSRU, SRV), whether off-shore or near-shore, are not covered by this document even if some concepts, principles or recommendations could be applied. However, in case of berthed FSRU with LNG transfer across the jetty, the following recommendations apply for the jetty and topside facilities. In case of solutions using floating storage unit (FSU) and land-based re-gasification solution, the on-shore part is covered by these standard recommendations. This document is not applicable for installations specifically referred or covered by other standards, e.g. LNG fuelling stations, LNG road or rail tankers. Plants with a storage inventory from 5 t up to 200 t are covered by [36].
