Calibration of Hydrodynamic Coefficients for a Semi-Submersible 10 MW Wind Turbine
Kvittem, Marit Irene; Berthelsen, Petter Andreas; Eliassen, Lene; Thys, Maxime (ASME 2018 37th International Conference on Ocean, Offshore and Arctic Engineering, Volume 10: Ocean Renewable Energy;OMAE2018-77826, Chapter, 2018-06-22)Hydrodynamic model tests and numerical simulations may be combined in a complementary manner during the design and qualification of new offshore structures. In the EU H2020 project LIFES50+ (lifes50plus.eu), a model test ... -
Effect of Wake Meandering on Aeroelastic Response of a Wind Turbine Placed in a Park
Panjwani, Balram; Kvittem, Marit Irene; Eliassen, Lene; Ormberg, Harald; Godvik, Marte (Journal article; Peer reviewed, 2019-10-24)A wind turbine operating inside a wind farm is subjected to increased turbulence intensity and reduced wind speeds resulting in increased fatigue loadings and reduced power production. Furthermore, meandering of the wakes ... -
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 ... -
LFCS Review report – Structure and mooring response - OC2018 A-073-WP3/WP4
Leira, Bernt; Kvittem, Marit Irene; Alsos, Hagbart Skage; Fylling, Ivar Johan (Research report, 2019-04-29)A review is performed on structural and mooring response analysis work in relation to Large Floating Coastal Structures and the planning of long floating bridges across fjords. The review contains observations on global ... -
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 ...
