Subsea Pipelines and Risers

Professor Yong Bai is the President of Offshore Pipelines and Risers, Inc. in Houston, and also the director of the Offshore Engineering Research Center at Zhejiang University. He has previously taught at Stavanger University in Norway and has also worked with ABS as manager of the Offshore Technology Department and DNV as the JIP project manager. Yong obtained a Ph.D. in Offshore Structures at Hiroshima University, Japan in 1989. Yong has authored more than 100 papers on the design and installation of subsea pipelines and risers and is the author of Marine Structural Design and Subsea Pipelines and Risers. Dr. Qiang Bai obtained a doctorate for Mechanical Engineering at Kyushu University, Japan in 1995. He has more than 20 years of experience in subsea/offshore engineering including research and engineering execution. He has worked at Kyushu University in Japan, UCLA, OPE, JP Kenny, and Technip. His experience includes various aspects of flow assurance and the design and installation of subsea structures, pipelines and riser systems. Dr. Bai is the coauthor of Subsea Pipelines and Risers.
