Model-based Detection for Ice on Wind Turbine Blades
(Master thesis, 2017)Wind power to cold climate sites is attractive because of favorable wind conditions and low population density. However, icing of wind turbine blades remains one of the main challenges for cold climate sites. Ice formation ... -
Monitoring of Fatigue Damage for Offshore Wind Turbine Foundations - Investigating Operation Strain Estimation Techniques
(Master thesis, 2017)A global focus on the shift to renewable energy has introduced international targets for sustainable energy production, which have strongly increased the interest in offshore wind turbines (OWT s). In order to make offshore ... -
Mooring system design for a floating wind farm in very deep water - European Wind Energy Master Thesis
(Master thesis, 2019)Offshore floating wind turbines are one of the newest technologies in the renewable markets today. The world s first floating wind farm, the Hywind Scotland Pilot Park, was commissioned in October 2017 and has been competitive ... -
Optimizing the Structural Lifetime of Monopile-based Offshore Wind Turbines with Genetic Algorithms: Is it worth planning for Lifetime Extension?
(Master thesis, 2017)Optimization of structures in a domain with large uncertainties is rather difficult. This also applies for the offshore wind energy sector. For current offshore wind energy development locations with monopile-based support ... -
Pile tip deformation caused by obstacles
(Master thesis, 2018)To identify the pile tip deformation, a finite element model is established. Six volume elements over the thickness are required at the contact zone to model the pile-boulder interaction accurately. Axial- and lateral soil ... -
Predicting scour around offshore wind turbines using soft computing techniques - Comparing Genetic Programming with Existing Scour Prediction Methods.
(Master thesis, 2015)In this report a prediction method is developed for scour around monopiles. A soft computing technique called genetic programming (GP) is used to create a scour prediction formula that can compute scour in all offshore ... -
Rational Upscaling and Modelling of a Semi-Submersible Floating Offshore Wind Turbine
(Master thesis, 2016)Floating offshore wind turbines are taking on more and more prominence, as the industry moves towards larger turbines, farther offshore, in deeper water. The increase in turbine size can reduce the costs of offshore wind ... -
Seismic Inversion for Identification of Soil Stiffness and Damping for Offshore Wind Turbines
(Master thesis, 2016)Non-invasive in-situ measurements can determine the soil properties in an undisturbed way, providing a more accurate characterization of the soil stiffness and damping. This report focuses on the multichannel analysis of ... -
State-of-the-art design methods for wind turbine towers
(Master thesis, 2015)The costs of wind energy have to be reduced in order to be competitive with conventional methods to generate electricity. The tower costs contribute significantly to the costs of a wind turbine. This thesis aims to suggest ... -
Stress analysis of a monopile foundation under the hammering loads
(Master thesis, 2017)The installation of monopile is a very important process in offshore wind turbine construction. Duringthemonopilebeingdrivendownbyhydraulichammer,hugeenergytransfersfromham mer to pile, which may cause monopile inclination. ... -
Structural Design and Dynamic Analysis of a Tension Leg Platform Wind Turbine, Considering Elasticity in the Hull
(Master thesis, 2016)There is an increasing interest in using offshore wind turbines in deeper waters. The tension leg platform wind turbine (TLPWT) is seen as a promising concept for this. Low production costs and limited motions give the ...
