Oil and gas exploration is a major industry in Australia. Collapse problems in the soil to which structures such as oil rigs are anchored are a major challenge, involving issues of safety, longevity and maintenance. Research on this topic has been devoted to non-crushable sands, but Australia's offshore seabed is rich in breakable calcareous sediments. We will create a novel theory and visualisation techniques that will allow us to gain a deep understanding of sand crushing and will be a major step towards minimising the occurrence of catastrophic failures in the offshore oil and gas industry.

石油和天然气勘探是澳大利亚的主要产业。石油钻井平台等结构所锚定的土壤中的坍塌问题是一个重大挑战，涉及安全、寿命和维护问题。关于这一主题的研究一直致力于不可压碎的沙子，但澳大利亚的近海海底富含易碎的钙质沉积物。我们将创建一个新的理论和可视化技术，使我们能够深入了解砂破碎，并将朝着减少海上石油和天然气行业灾难性故障的发生迈出重要一步。
