Comparison of different approaches to load calculation for the OWEC Quattropod jacket support structure
Zwick, Daniel; Schafhirt, Sebastian; Brommundt, Matthias; Muskulus, Michael; Narasimhan, S; Mechineau, Jonathan; Haugsøen, Per (Journal article; Peer reviewed, 2014)Accurate load simulations are necessary in order to design cost-efficient support structures for offshore wind turbines. Due to software limitations and confidentiality issues, support structures are often designed with ... -
Improved design of the support structure for the NOWITECH 10 MW Reference Turbine
Sandal, Kasper (Master thesis, 2014)The aim of this thesis is to improve the support structure for the Nowitech 10 MW reference turbine (NRT) by optimizing the thickness and diameter of legs and braces section by section. This is a so called full-height ... -
Kost/nytte-forhold og slitasjemekanismer i ekstruderskruer for PVC
Duaas, Trine; Svingen Lunnan, Vebjørn; Brøske, Simen (Bachelor thesis, 2021)Hensikten med denne oppgaven er å avdekke slitasjemekanismer på ekstruderskruer som prosesserer PVC og finne fornuftig krysningspunkt mellom kost/nytte-forhold. For å avdekke slitasje ble det benyttet lysmikroskop, SEM og ... -
Simulation and Optimization in Offshore Wind Turbine Structural Analysis
Zwick, Daniel (Doctoral thesis at NTNU;2015:80, Doctoral thesis, 2015)The public interest in renewable energy resources is continuously growing as issues of pollution and shortage of limited resources as coal or oil become evident. One promising technical solution for the extraction of ... -
Topology optimization of jacket support structures with genetic altorithm
Barcena Pasamontes, Lucia; Gomez Torres, Fernando (Master thesis, 2014)This thesis is a study of the optimization of the support structure for offshore wind turbines with a genetic algorithm. The optimization of these structures plays an important role in the plan for reduction of the costs ...
