Design, Modelling and Analysis of a Large Floating Dock for Spar Floating Wind Turbine Installation
Jiang, Zhiyu; Yttervik, Rune; Gao, Zhen; Sandvik, Peter Christian (Journal article; Peer reviewed, 2020-07)Installation of floating wind turbines at the offshore site is a challenging task. A significant part of the time efficiency and costs are related to the installation methods which are sensitive to weather conditions. This ... -
Numerical modelling of hydrodynamic responses of Ocean Farm 1 in waves and current and validation against model test measurements
Jin, Jingzhe; Su, Biao; Dou, Rui; Luan, Chenyu; Li, Lin; Nygaard, Ivar; Fonseca, Nuno; Gao, Zhen (Peer reviewed; Journal article, 2021)With the continuous growing of the aquaculture industry and increasingly limited fish farming sites at close to shore areas both in Norway and worldwide, there is a need to develop fish farms suitable for aquaculture ... -
Optimization of Offshore FPV Modules in Early Design Phase
Jin, Jingzhe; Zhang, Liqing; Lin, Zhiliang; Kong, Jiehong; Gao, Zhen (Chapter; Peer reviewed, 2024)Offshore Floating Photovoltaic (FPV) systems are gaining attention due to the high Technology Readiness Levels (TRL) of PV panels and offshore structures. Numerous offshore FPV design proposals exist, but none have yet met ... -
Stochastic dynamic load effect and fatigue damage analysis of drivetrains in land-based and TLP, spar and semi-submersible floating wind turbines
Rasekhi Nejad, Amir; Bachynski, Erin Elizabeth; Kvittem, Marit Irene; Luan, Chenyu; Gao, Zhen; Moan, Torgeir (Journal article; Peer reviewed, 2015-07)This paper deals with the feasibility of using a 5 MW drivetrain which is designed for a land-based turbine, on floating wind turbines. Four types of floating support structures are investigated: spar, TLP and two ... -
Yaw misalignment in powertrain degradation modeling for wind farm control in curtailed conditions
Khazaeli Moghadam, Farid; Gao, Zhen; Chabaud, Valentin Bruno; Chapaloglou, Spyridon (Peer reviewed; Journal article, 2024)A framework characterizing the degradation of wind turbines for use in multiple-input damage-aware farm control is suggested. The focus is on the fatigue damage of the powertrain (drivetrain + generator) system, but the ...
