Stability Design for Concrete Mattresses

This paper reviews design works previously carried out for a project in the North West Shelf of Australia and proposes an industry design methodology.

Concrete mattresses are widely used within the offshore industry for scour control, stabilisation and protection. There is currently no uniform industry methodology for concrete mattress stability design for any application of concrete mattresses. This paper reviews design works previously carried out for a project in the North West Shelf of Australia and proposes an industry design methodology.

This methodology encompasses the application of recognised pipeline codes and standards, and the requirements and results of 2D and 3D Computational Fluid Dynamics (CFD) modelling as well as physical model testing.
