    Abstract

    [Truncated] The North West Shelf of Australia is a region with significant reserves of oil and natural gas. In order to extract these reserves, it is necessary to establish facilities at sites in water depths ranging up to 200 m. These facilities can take the form of floating platforms, concrete gravity structures, conventional steel jackets or subsea installations. The common theme for all of these structures is that they must be able to resist substantial lateral loads applied by the severe storm loading that is prominent in this region of the world.
    One of the more common methods of resisting lateral loads is with piles. This method of support is made difficult in this region because of the prevalence of calcareous sediments that have been found to offer inferior bearing resistance compared with silica sands. The varied levels of cementation, and tendency to undergo large volume changes when sheared, combine to make this a difficult foundation material.
