Out for Comment: IGEM/UP/22 – Whole lifecycle management of Vacuum Insulated Tanks for Liquified Natural Gas
This Standard has been drafted by an Institution of Gas Engineers and Managers (IGEM) Panel, appointed by IGEM’s Gas Transmission and Distribution Committee and has been approved by IGEM’s Technical Coordinating Committee on behalf of the Council of IGEM.
We are currently seeking comments on IGEM technical standard IGEM/UP/22 – Whole lifecycle management of Vacuum Insulated Tanks for Liquified Natural Gas.
This Standard applies to the design and operation of LNG Vacuum Insulated Tanks (VIT) in excess of 200 Tonnes and operating above 500mBar, it shall be applicable for all new installations.
The equipment system boundary shall encompass the vessel, its supporting structure, spillage retention bunds and valving, and include any other valves and fittings required for its own operation such as vessels, gauges, pipework systems, and fill valves.
The following items of plant are outside of the main VIT equipment system boundary and are outside of the scope of this standard:
- LNG transfer pumps
- Vaporisers
- Atmospheric storage tanks (including tanks below 3.5 barg)
- Design of compressors
- Conventionally insulated bulk storage, e.g., single wall tanks with polyurethane insulation
- Buried storage
- Associated LIN tank and LIN system
- Product quality and custody transfer measurement
- Foam suppression and other arrangements for active fire protection
This Standard provides guidance and mandatory requirements to be applied for each stage of the lifecycle of the asset:
- Conceptual and Detailed Design
- Testing
- Commissioning
- Operation
- Maintenance and Inspection
- Decommissioning and disposal
If you wish to comment on this Standard, please download the draft and comment form and return by the deadline of 29 January 2025.
