A Time-Domain Method for Hydroelastic Analysis of Floating Bridges in Inhomogeneous Waves
Fu, Shixiao; Wei, Wei; Ou, Shaowu; Moan, Torgeir; Deng, Shi; Lie, Halvor (ASME Proceedings | Torgeir Moan Honoring Symposium;OMAE2017-62534, Chapter, 2017-06-25)Based on the three dimensional potential theory and finite element method (FEM), this paper presented a method for time-domain hydroelastic analysis of a floating bridge in inhomogeneous waves. A floating bridge in both ... -
Analysis of lifting operation of a monopile for an offshore wind turbine considering vessel shielding effects
Li, Lin; Gao, Zhen; Moan, Torgeir; Ormberg, Harald (Journal article; Peer reviewed, 2014-12)This study addresses numerical simulations of the lifting operation of a monopile for an offshore wind turbine with a focus on the lowering process. A numerical model of the coupled system of the monopile and vessel is ... -
Correlation between Acceleration and Drivetrain Load Effects for Monopile Offshore Wind Turbines
Rasekhi Nejad, Amir; Bachynski, Erin Elizabeth; Li, Lin; Moan, Torgeir (Journal article; Peer reviewed, 2016-09)This paper investigates the correlation between the tower-top axial acceleration and the load effects in drivetrain components in a monopile (bottom-fixed) offshore wind turbine. In designing offshore wind turbines, it is ... -
Inhomogeneous wave load effects on a long, straight and side-anchored floating pontoon bridge
Dai, Jian; Leira, Bernt Johan; Moan, Torgeir; Kvittem, Marit Irene (Journal article; Peer reviewed, 2020-07)In this paper, we present a numerical study on the hydroelastic response of a 4.6 km long fjord crossing floating bridge subjected to wave loads. The bridge is straight in design and supported by 35 pontoons along its full ... -
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 ...
