2022 was a pivotal year for corrosion research with our researchers at Deakin University delivering a number of finds.This included:Prototyping of a new pipeline corrosion control technology that can minimise the most serious corrosion threats to buried pipelines; corrosion under disbonded coatings; and stray current corrosion from conventional cathodic protection systems.Prototyping and demonstration of this technology is a critical step in developing a practical product for future use by our industry.An independent and critical analysis of existing and new trenchless technologies enables us to rehabilitate or repurpose existing pipeline assets.This project developed our understanding on the suitability of trenchless technologies for gas pipelines,and compared performance and working principles to understand their advantages and limitations.The traditional method of pipeline rehabilitation through digging-up operation can be costly.The key research outcome of this project is a stronger knowledge base for the Australian pipeline industry,and to assist with the selection of coatings and linings for the trenchless rehabilitation of pipelines.This technology also has the potential to be used for repurposing pipelines for transporting future fuels such as hydrogen.
