    Abstract

    © 2015 Taylor & Francis Group, London, UK. Skirted foundations are commonly used for offshore installations to enhance foundation capacity. One of the key design considerations is the determination of the skirt installation load to achieve the skirt penetration necessary for stability. Such installation loads are often calculated using correlations with the Cone Penetration Test (CPT) end resistance but there is little guidance on how CPT data can be applied for load estimations in carbonate soils. This paper describes the results from a centrifuge investigation involving skirt installations into carbonate soils. Installation resistances observed for five different structures in Australia’s North West Shelf are also examined with a view to providing guidance on how skirt penetration resistance (under self-weight) can be estimated using CPT data in carbonate soils.
