The project included an early phase study of the LNG tank with regards to location, tank type selection, sizing and design pressure

rozwiązanie

Norconsult designed a full containment LNG tank according to the European standards EN 1473 and EN 14620. The design includes an inner tank of 9 percent nickel steel, and an outer tank of cast concrete. The design included evaluation and selection of insulation materials to minimize evaporation (BOG) of LNG stored at -162°C. Abacus was applied to perform finite element analysis (FEA) for the tank, based on earthquake calculations from a response spectrum analysis. Other software such as 3D analysis, Staad-Pro and Concrete Design - Postprocessing (developed by Norconsult) was also used in the tank design. Norconsult assisted the owner during the construction phase and follow up towards accredited control body DNV GL and process contractor.

Wyniki

The project was delivered at budget cost and on time. It was erected as planned, with no harm to personnel or equipment.
