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.Read moreRead less

Using Sandwich Pipe for Pipeline Vibration Control. Pipelines are important structures but are vulnerable to different types of damage. This damage is often associated with pipeline vibration. It is important to control adverse vibrations to reduce the risk of catastrophic damage.

Pipelines are important structures but are vulnerable to different types of damage. This damage is often associated with pipeline vibration. It is important to control adverse vibrations to reduce the risk of catastrophic damage. This project proposes using sandwich pipe to suppress different sources of vibrations that may be experienced during the lifetime of the pipeline. Analytical, numerical and experimental investigations will be carried out to demonstrate the feasibility of the proposed method. The project aims to develop direct applications for designing pipelines to suppress different sources of vibration and to guarantee the safety of pipelines.Read moreRead less
