Research Program 3 - Design and Construction

Advanced Design and Construction of Energy Pipelines

This program aims to improve the design related factors in Australian pipelines that affect cost, reliability and safety. Active research within the area focuses on fracture control, hydrostatic testing, thermal transients and issues with new energy fluids.

pipelineMethods for fracture control in small diameter natural gas and other energy fluid pipelines is a main theme for this research program. Shock tube test experiments will be validated by computational fluid mechanics modelling to quantify pipe toughness requirements. Another focus of the research is the improvement of accuracy for hydrostatic leak testing of large diameter pipelines. This will result in a new approach to the planning, completion and data analysis of hydrostatic testing of large volume pipeline sections.

Research relating to future energy pipelines carrying energy fluids such as CO2, H2 and H2/CH4 blends will also be undertaken with the aim to assist industry with anticipating, planning and designing the next generation of new and reused pipelines for transportation of energy and combustion products.

The Steering Committee overseeing RP3 is chaired by Phil Colvin (Jemena) and the Program Leader is A/Prof Cheng Lu (University of Wollongong).
