3580 Guidelines on integrity management for LNG operations

Overview:

The purpose of this publication is to provide information and guidance on the identification and management of corrosion and degradation threats as part of the integrity management of LNG liquefaction and re-gassification facilities.

The scope of this guidance document focuses on the following equipment and systems for LNG facilities:
− process, utility and safety-related pressure systems;
− pipelines (within the facility battery limits);
− steel structures, including jetties;
− atmospheric and low-pressure storage tanks, and
− LNG loading arms.

The main body of the guidelines is applicable to on-land liquefaction and import/ re-gassification facilities as these represent the vast majority of LNG facilities. Process and utility systems for floating liquefaction (FLNG) or storage and re-gassification (FSRU) facilities are generically similar in nature to those used on land, modified as appropriate to take account of wind and wave action on the process itself and equipment and structures, and the vastly reduced plant layout footprint. As such, integrity management activities are broadly similar and therefore the guidance in this document may be applied as appropriate to both on-land and floating facilities with any additions or exceptions detailed in Annex C.
