Summary

In anticipation of future development of offshore facilities around Australia, this project was undertaken to meet challenges posed by deep water and the possible lack of substantial cemented near-surface sediments.

It aimed to formulate a design framework for alternative foundation systems, in weak calcareous sediments, that was calibrated through physical model tests.

Project outcomes included soil characterisation, demonstration of the validity of a newly developed load transfer curve formulation for weak sediments, and validation of current design approaches for estimating penetration resistance of cylindrical skirts into uncemented sediments.

Keywords: offshore foundations, calcareous sediments, North West Shelf, load transfer curves, cylindrical skirts
