Summary
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. 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 o ....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. 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
Development of novel inerter-based damper for platform vibration control. This project aims to develop a novel inerter-based damper to mitigate the excessive vibrations of offshore floating platforms (OFP), which are widely used in the offshore industry for oil exploration. Harsh environmental loads such as wind and waves can induce excessive vibrations to OFPs and endanger their safety and stability. This project aims to develop a novel inerter-based damper that can produce a considerable appar ....Development of novel inerter-based damper for platform vibration control. This project aims to develop a novel inerter-based damper to mitigate the excessive vibrations of offshore floating platforms (OFP), which are widely used in the offshore industry for oil exploration. Harsh environmental loads such as wind and waves can induce excessive vibrations to OFPs and endanger their safety and stability. This project aims to develop a novel inerter-based damper that can produce a considerable apparent mass that is much larger than its physical mass through an amplifying mechanism by translating the linear motion into high-speed rotational motion, which can significantly reduce the mass and cost of the damper. Benefits of the project include more economical and safer OFP designs, which are expected to improve the competitiveness of Australian pillar oil and gas industries.Read moreRead less
Building Australia's Offshore Oil and Gas Industry on Solid Foundations: characterising multilayered soils for offshore foundation design. This project aims to characterise soils with multilayers for offshore foundation designs. The commonly used site investigation tools, cone, T-bar and ball penetrometers, will be studied using advanced large deformation finite element analysis and novel centrifuge technics. The outcome of this study will provide guidelines to interpret soil layer information a ....Building Australia's Offshore Oil and Gas Industry on Solid Foundations: characterising multilayered soils for offshore foundation design. This project aims to characterise soils with multilayers for offshore foundation designs. The commonly used site investigation tools, cone, T-bar and ball penetrometers, will be studied using advanced large deformation finite element analysis and novel centrifuge technics. The outcome of this study will provide guidelines to interpret soil layer information and soil design parameters from site investigation data, that is, penetrometers’ penetration resistance profiles. The guidelines will fill the knowledge gap in this area and will provide offshore design engineers with more reliable soil parameters for safer and more economical foundation designs.Read moreRead less
Vulnerability mapping of hazards and economic loss assessment of offshore oil and gas platforms subject to accidental explosion and fires. In Australia, up to 100 offshore oil and gas wells per year are drilled, but fire and explosion are a risk. This project develops vulnerability maps of offshore platforms subjected to accidental explosions, so that economic loss, environmental and social impact can be effectively assessed based on these factors and mitigation measures can be introduced.
