Time:10：00-12：00, Jan. 14^th.

Venue:A536, Mingzhilou Building

Bio.：Zhao Liang, a senior engineer in geotechnical engineering at Fugro Australia. He graduated from Tianjin University with a PhD in engineering in 2012 and has worked for Worley Parsons Geotechnical Consulting in Singapore, the Centre for Offshore Foundation Systems at the University of Western Australia, the world's largest geotechnical investigation and consulting company, and Fugro, the world's largest geotechnical investigation and consulting company. His work is centered on deep-sea mooring foundations and subsea pipelines, serving the development of marine energy. His research interests include offshore wind power suction anchor foundation design optimization, subsea pipelines and mutual contact between anchor chain and soil, etc. He has participated in an Australian National Research Foundation Board project and published 18 SCI papers. Meanwhile, he has accumulated rich practical experience in cutting-edge practical engineering consultancy. He has participated in a number of major energy development projects at home and abroad, including Mozambique gas development, Qatar oil and gas development, Bangladesh gas pipeline project, South China Sea gas project and Taiwan Changhua wind power project, and a number of oil and gas development projects in Indonesia by Ente Nazionale Idrocarburi (ENI).

Abstract：The interaction between the mooring chain and soil plays an important role in offshore anchoring foundation analysis, as it directly determines the load magnitude and direction applied to the foundation. A more realistic assessment is achieved by analyzing the mooring anchor as an integrated system rather than treating the chain and foundation separately, which necessitates numerical modelling of the chain. A practical numerical approach to simulate the chain cutting through soil under the tension load will be introduced. The numerical modelling provides more insights into the very low friction mobilization for chains at deep depths near the padeye.
