Malfliet, Jari (author)Wind estimation plays an important role in many aspects of our world, both for nowcasting and forecasting. This is also true for aircraft flight routes; where wind field knowledge can contribute to flight planning and safety. Aircraft can relay flight information back to ground-based receivers, from which local wind measurements can be derived....master thesis 2023

Groenewegen, Rik (author)The first large offshore wind farms installed in the North Sea Region (NSR) soon reach their technical end of lifetime. The wind turbines in these farms will have to be decommissioned after power production has stopped. Currently offshore wind turbines are decommissioned based on a method called reversed installation, a time consuming and...master thesis 2022

Tempelman, Koen (author)As the world's population keeps increasing and the rate of urbanizations increases, The rate at which high-rise structures are being built is skyrocketing. In the Netherlands, this is no different. It is expected that the amount of high-rise structures taller than 70 meters will more than double in the coming 20 years. As these structures become...master thesis 2022

Uritsky, Vadim (author)Due to the increasing interest in modelling floating offshore wind turbines, simulation tools need to be adapted from fixed-base applications to surge applications. In this study, an open-source inviscid 3D panel method named Vortexje was adapted for surge motion and its ability to capture the physics of severe surge motion (when the rotor...master thesis 2021

Driessen, Mark (author)Current service and installation activities to offshore wind turbines (OWTs) are mainly carried out by jack-up vessels. These vessels are less susceptive to disturbances caused by sea waves when they lift their hull from the water level by jacking down multiple legs to the seabed. An alternative is a crane mounted on a floating vessel, which has...master thesis 2021

Donkers, Paul (author)The goal of this thesis is to create a theoreticalmodel that captures the influence of wind on the horizontal and vertical salinity distribution in an estuary, as well as the dynamics that arise within the estuary. A secondary, numerical model, that uses fewer assumptions, will be developed and analysed. This serves to determine whether the...master thesis 2020

Sonneveld, Michelle (author)As buildings get taller and lighter, structural engineers are increasingly faced with the consequences of the dynamic response of high-rise buildings to wind. Damping is an important property for the dynamic response of high-rise structures, but is a combination of many mechanisms, which makes it a complex phenomenon to account for in the...master thesis 2020

van Vliet, Marc (author)This report investigates the potential reduction of steel weight for offshore wind turbine supporting jacket structures, if conventional welded joints are replaced by innovative wrapped FRP joints. This new type of connection is under development by Dr. Marko Pavlovic at the Delft University of Technology, and shows outstanding fatigue...master thesis 2019

Gerrmann, Xander (author)Airborne wind energy (AWE) is an emerging field that aims to revolutionize the wind energy sector.This work focuses on the aspects of modeling AWE kite flight behavior. Research on such modelsis important since new or improved models can potentially reduce development time and costs andprovide insight in the role of key system parameters.This...master thesis 2019

Fortuijn, Lars (author)In 2003, it was established that the sea dike between Petten and Camperduin was insufficiently safe.<br/>To ensure the safety of the hinterland against flooding, this part of the Dutch sea defence system needed to be strengthened.<br/>During the design process, the most favourable variant was to construct a dune and beach system in front of the...master thesis 2018

Faber, Mark (author)Aeroelastic codes are fundamental for the design of wind turbines and the prediction of instabilities. Such codes rely on engineering models which limit their accuracy. With wind turbine blades becoming more slender to lower the costs, it is important to reduce these uncertainties to maintain a safe and stable turbine design. The dynamic stall...master thesis 2018

Lengkeek, Thijs (author)The wind energy industry is booming. In 2017 the installed wind capacity has overtaken coal as the second largest form of power generation in Europe. Costs of wind farms are driven down, and even the first offshore wind-farm contract without subsidies is a fact. Installing the Wind Turbine Generators (WTGs) more efficiently increases the profit...master thesis 2018

van Ramshorst, Justus (author)Near-surface wind speed is typically only measured by point observations. The so-called Actively Heated Fiber-Optic (AHFO) technique, however, has the potential to provide high-resolution distributed observations, allowing for better understanding of different processes. However, before it can be widely used, its performance needs to be tested...master thesis 2018

Fikkers, Coen (author)The standard sign gantries at the highways in the Netherlands have different geometrical and structural characteristics than sign gantries in other countries. The sign gantries have in total four oblique columns instead of two straight columns and have a triangular shaped spatial truss beam. The design loads that are currently taken into account...master thesis 2018

Vlemmix, Christian (author)Since both the aircraft and wind energy sectors are experiencing rapid growth, improvements must be made in terms of noise reduction as to enable growth whilst fulfilling the restrictions on noise pollution. An open-section vertical wind tunnel with an anechoic test chamber has recently been constructed at the Delft University of Technology, in...master thesis 2017

Doekemeijer, B.M. (author)Wind turbines are often grouped together for financial reasons, but due to wake development this usually results in decreased turbine lifetimes and power capture, and thereby an increased levelized cost of energy (LCOE). Wind farm control aims to minimize this cost by operating turbines at their optimal control settings. Most state-of-the-art...master thesis 2016

Van Laerhoven, C.R. (author)Since their development in the 1970s, mesoscale atmospheric models have been used for a variety of meteorological applications. Over the years, the models have evolved and nowadays, state-of-the-art atmospheric models are capable of operating on spatial resolutions in the order of kilometres. In the hydraulic engineering community, atmospheric...master thesis 2016

Koning, W.J.F. (author)Experimental techniques to measure rotorcraft aerodynamic performance are widely used. However, most of them are either unable to capture interference effects from bodies, or require an extremely large computational budget. The objective of the present research is to develop an XV-15 Tilt Rotor Research Aircraft rotor model for investigation of...master thesis 2015

Getreuer, R.E. (author)Offshore wind energy has become a very hot topic in northwest Europe, both from an industrial as from an academic point of view. Research on transmission grids for offshore wind energy focuses predominately on radial grids and HVDC. This study broadens this general scope by taken mesh grids and HVAC as the starting point. With the use of load...master thesis 2015
