Wang, Huanhuan; Yang, Jin; Zhang, Dongyufu; Sævik, Svein; Leira, Bernt Johan; Xu, Fei; Li, Xiao (Peer reviewed; Journal article, 2022)Small-scale model tests of a drilling riser were conducted, aiming at a better understanding of the mechanical transfer of forces from the drilling riser to the wellhead. The tests were conducted in a water tank with ... -
Mechanical analysis of drilling riser based on pipe-in-pipe model
Wang, Huanhuan; Yang, Jin; Sævik, Svein; Leira, Bernt Johan; Zhang, Dongyufu; Hu, Zhiqiang; Xu, Fei; Wang, Wenxing (Journal article, 2021)Due to the presence of a drill string inside drilling risers, the mechanical analysis becomes somewhat challenging which has attracted attention from design engineers and drilling operators. The purpose of this study is ...
