Dynamic Analysis of a Floating Wind Turbine with a Hydraulic Transmission System
Yang, Limin; Jiang, Zhiyu; Gao, Zhen; Moan, Torgeir (Chapter, 2015)A 5 MW spar-type floating wind turbine equipped with high-pressure hydraulic transmission machinery is presented in this paper. The hydraulic transmission system consists of a hydraulic pump, a nonreturn check valve, a ... -
Integrated dynamic analysis of a spar floating wind turbine with a hydraulic drivetrain
Jiang, Zhiyu; Yang, Limin; Gao, Zhen; Moan, Torgeir (Peer reviewed; Journal article, 2022)Conventional drivetrains with gearbox failures are associated with major downtime in offshore wind turbines. This impacts the maintenance cost and cost of energy. A hydraulic transmission eliminates the need for gearbox ... -
Stochastic dynamic system analysis of wave energy converter with hydraulic power take-off, with particular reference to wear damage analysis
Yang, Limin (Doktoravhandlinger ved NTNU, 1503-8181; 2011:102, Doctoral thesis, 2011)The study of the renewable energy has drawn increasing attention in the recent years. Wave energy with its relatively high power density is a major resource that has remained untapped until recently. Different types of ... -
Time-domain Roll Motion Analysis of a Barge for Transportation of an Offshore Jacket Structure
Mehn-Andersen, Ingrid (Master thesis, 2018)This paper presents a literature study on roll motions for barges, and time domain and frequency domain simulations. In addition, results from time and frequency domains have been compered in regular and irregular waves ...
