Research Program 3 - Design and Construction
Advanced Design and Construction of Energy Pipelines
This program aimed to improve the design related factors in Australian pipelines that affect cost, reliability and safety. Research within the area focused on fracture control, hydrostatic testing, thermal transients and issues with new energy fluids.
Methods for fracture control in small diameter natural gas and other energy fluid pipelines was a main theme for this research program. Shock tube test experiments were be validated by computational fluid mechanics modelling to quantify pipe toughness requirements. Another focus of the research was the improvement of accuracy for hydrostatic leak testing of large diameter pipelines. This supported industry with new insight into 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 was 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 was chaired by Phil Colvin (Jemena) and the Program Leader was A/Prof Cheng Lu (University of Wollongong).
