|Friday Afternoon Seminar: Mr Jiayue Liu : Development of a non-linear riser-seabed interaction model (UWASCR)
Due to the non-linear nature of the riser-soil interaction, dynamic response and fatigue design of Steel catenary risers (SCRs) in the touchdown zone (TDZ) are among the most complicated engineering challenges. An advanced non-linear SCR-seabed interaction model (UWASCR) has been developed to capture the hysteretic behaviour of the seabed response and the increasing penetration of the pipe under cycles of load in the vertical plane. Results from UWASCR have been validated against the industry-wide engineering software OrcaFlex. Insights gained are included and further research is ongoing.
ABOUT THE SPEAKER
Mr. Jiayue Liu started his PhD at COFS on March 2013, under the supervision of Asst/Prof. Mehrdad Kimiaei and W/Prof. Mark Randolph. He obtained his bachelor degree from Tsinghua University, China and master degree on Engineering Mechanics from the Institute of Mechanics, Chinese Academy of Sciences. Then he started his career as a Structural Engineer in China National Offshore Oil Corporation (CNOOC). He worked for 4 years in different offshore projects including fix, floating platforms and subsea structures before he joined UWA. He is now working on numerical modelling of SCR (steel catenary riser)-seabed interaction and effect of non-linear interaction on fatigue performance of SCRs.
