Installation and equipment for liquefied natural gas - Design of onshore installations EN 1473:2021

Publication date:   Sep 16, 2021

Scope

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).
This document is applicable for plants with an LNG storage 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 car 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.
Plants with a storage inventory from 5 t up to 200 t are covered by [5].
