A major element of the Port Pirie Transformation Project was the construction of a 30m x 30m 75m tall building for the new Top Submerged Lance Furnace and Waste Heat Boiler. The building was constructed and fitted out off shore and shipped to Australia in modules for final erection. The requirements for transport and handling of the large modules imposed a complex set of loading conditions that are not prescribed by the usual Australian Standards for structural design. The special loading conditions imposed by the operating process equipment are also not prescribed by the usual Australian Standards.
A “one-model” approach was implemented for structural design of the furnace building. Key success factors discussed in this paper are:
- Application of well-defined project design criteria.
- Use of structural analysis software with advanced modelling features.
- Leveraging the software capabilities through application of well-planned modelling strategies.
