TR 74:2020
Code of practice for storage, land transportation and handling of LNG
OVERVIEW
Sets out the design and operational requirements and recommendations for the inland handling, storage and land transportation of LNG.
Covers portable liquid cylinders (PLC), stationary storage facilities (e.g. microbulk tanks/bulk storage tanks) and the various means for transporting LNG applicable to bulk delivery and packaged gas delivery.
Specifies the minimum requirements for the design, construction and operation of an onshore LNG storage tank farm and does not cover the following:
• LNG liquefaction plant design and installation;
• off-shore LNG installations (e.g. floating installations);
• facilities such as a PLC trans-fill terminal (with exception of the storage tank), or temporary LNG/NG facilities being used for activities such as equipment commissioning;
• underground LNG storage tanks;
• design and specification for LNG vehicle fuel tanks and fuel stations.
Key hazardous scenarios in a risk assessment for the storage, land transportation and handling of LNG would be expected to include, but not limited to, the following:
• tank over pressure;
• tank over filling;
• cold embrittlement of carbon steel equipment and/or structures;
• loss of containment (leak) of LNG during unloading or loading operations;
• formation and dispersion of cold vapour clouds of LNG via poor vent stack design or discharge of NG gas in the tank farm;
• pipeline over pressure due to regulator failure;
• rapid phase transition.
