Drivetrains on floating offshore wind turbines: lessons learned over the last 10 years
R. Nejad, Amir; Torsvik, Jone (Peer reviewed; Journal article, 2021)This paper presents lessons learned from own research studies and field experiments with drivetrains on floating wind turbines over the last ten years. Drivetrains on floating support structures are exposed to wave-induced ... -
Dynamic Analysis in Design and Operation of Large Floating Offshore Wind Turbine Drivetrains
Torsvik, Jone (Doctoral theses at NTNU;2020:403, Doctoral thesis, 2020)This thesis presents a versatile rotor-bearing simulation model, including elements required to model rolling-element bearings as main bearings in large floating offshore wind turbines. Furthermore, the thesis presents new ... -
Experimental field study of floater motion effects on a main bearing in a full-scale spar floating wind turbine
Torsvik, Jone; Nejad, Amir R.; Pedersen, Eilif (Peer reviewed; Journal article, 2021)In this paper we present a full-scale experimental field study of the effects of floater motion on a main bearing in a 6 MW turbine on a spar-type floating substructure. Floating wind turbines are necessary to access the ... -
Main bearings in large offshore wind turbines: development trends, design and analysis requirements
Torsvik, Jone; Nejad, Amir Rasekhi; Pedersen, Eilif (Journal article; Peer reviewed, 2018)This paper discusses analysis requirements for design and operation of main bearings in modern multi-megawatt offshore wind turbines, motivated by the industry's search for reliable and cost effective main bearing solutions ... -
