This project aims to investigate the process of lifting objects off the seabed. Understanding this breakout process is the scientific basis for a variety of offshore applications such as oil and gas decommissioning, marine salvage and securing foundations under extreme storms. This project expects to advance the understanding of soil-fluid-structure interactions of this problem using innovative high-speed photography observations and advanced numerical coupled analyses. Outcomes will include a numerical tool, verified against a high quality experimental database, to predict the breakout process and uplift required for pressing offshore challenges. The ability for Australia’s engineers to predict lift procedures more accurately will contribute to safer operations in Australian waters and to the more economic harnessing of ocean resources.

该项目旨在研究将物体从海底提起的过程。了解这种破裂过程是各种海上应用的科学基础，例如石油和天然气退役，海上打捞和极端风暴下的基础保护。该项目希望通过创新的高速摄影观测和先进的数值耦合分析来促进对这一问题的土-流-结构相互作用的理解。成果将包括一个数字工具，验证了高质量的实验数据库，预测突破过程和隆起所需的紧迫的海上挑战。澳大利亚工程师更准确地预测提升程序的能力将有助于在澳大利亚沃茨更安全地作业，并有助于更经济地利用海洋资源。
