Deng, Shi; Ren, Haojie; Xu, Yuwang; Fu, Shixiao; Moan, Torgeir; Gao, Zhen (Journal article; Peer reviewed, 2020)In this paper, the drag forces on a rigid segment of a twin-tube submerged floating tunnel (SFT) under various Re number and submergence are experimentally investigated with a simplified rigidly connected tandem twin-cylinder ... -
Hydro-Elastic Analysis of a Floating Bridge in Waves Considering the Effect of the Hydrodynamic Coupling and the Shore Sides
Deng, Shi; Fu, Shixiao; Moan, Torgeir; Wei, Wei; Gao, Zhen (Chapter, 2018)A new numerical method, which is based on three-dimensional (3D) potential flow theory and finite element method (FEM), is used to predict the wave-induced hydroelastic responses of flexible floating bridges. The floating ... -
Numerical simulations for lift-off operation of an offshore wind turbine monopile
Deng, Shi (Master thesis, 2016)From this study, lift-off process of monopile in single crane vessel scenario and two vessels scenario are all considered. Challenges from environmental conditions and upending process are all cleared. In the single crane ... -
Numerical Study on the Dynamic Response of a Submerged Floating Tunnel Under Current Loads Based on the Segment Model Towing Test Results
Deng, Shi; Li, Shuai; Xu, Yuwang; Moan, Torgeir; Fu, Shixiao; Gao, Zhen (Chapter, 2020)Submerged floating tunnels (SFTs) are considered as one of the relevant concepts to replace ferry connection in the Norwegian Public Road Administration's plan to upgrade the E39 coastal highway. Current load including ...
