Fibreglass SIL Thickener Cover Olympic Dam

Fibreglass SIL Thickner Cover

DSA provided the design for a cover for the 4m diameter SIL Thickener at Olympic Dam. The roof was manufacture in four flanged section, that were bolted together on site.

The roof was designed for with local loading during installation, a 0.25 kPa distributed load and 1 kPa vacuum. Due to the support arrangement and geometry, a FEA was used to design the roof to provide the a solution that was not overly conservative. The end result was an economical solution that was light weight and easy to install on site.

DSA has over 25 years in composite design, engineering, inspections and compliance.
