Hemelaar, Senne (author)While the assumption of incompressible flow has been the prevailing standard for numerical simulations of wind turbine aerodynamics, the limit of this assumption is approached as the industry progresses towards increasingly higher operational tip speeds. This thesis explores the implications of compressibility and transonic flow phenomena,...master thesis 2024

den Butter, Robbert (author)Background: Bilateral tubal ligation (BTL) is the most common method of contraception worldwide because it is safe and effective. However, its accessibility remains unequal among women in rural India, in part due to a lack of laparoscopic equipment. Rural hospitals therefore resort to gas insufflation-less laparoscopic surgery (GILLS) because it...master thesis 2024

Eerden, Koen (author)This MSc thesis presents an investigation into motion control systems aimed at reducing swing motion of a lifting load during offshore heavy lifting operations. Two distinct models are developed for this objective. Subsequently, an analysis is done to assess the impact of various control aspects.<br/><br/>First, an assessment of the offshore...master thesis 2023

Koetzier, Daan (author)Floating offshore wind turbines offer a means to access wind resources in waters that are too deep for bottom-fixed offshore wind turbines. To operate a floating wind farm, it must be possible to perform maintenance on the turbines. A critical maintenance aspect is the exchange of a major component such as a blade. It involves a lift of a large...master thesis 2023

Berkouwer, Laurens (author)For the installation of suction pile jackets, a new installation method initiated by SPT Offshore could extend the allowable size for suction pile jackets used as foundations for offshore wind turbines. This method involves installing the suction piles separately from the jacket frame. First, the suction piles are installed on the seabed. Then,...master thesis 2023

Veršnik, Ana (author)The success of offshore wind farm installations is often related to the costs and time taken to be completed. Current installation strategies require several critical offshore lifts for the completion of a single wind turbine, as in most cases each component gets installed separately. This is time-consuming and has a direct link to the cost of...master thesis 2023

L'Ortije, Jasper (author)With a booming eVTOL market, many new companies will design their own vision of the future of urban transport. Therefore, a MATLAB flight dynamics model is needed to accurately design a Lift + Cruise Aircraft in the preliminary design phase. The MATLAB program is based on the EVE V3 aircraft by Embraer. The model successfully simulates an input...master thesis 2023

Sarıgöl, Barkin (author)Various potential flow methods with different assumptions are available to quantify the efficiency increase and thrust provided by a swirl recovery vane (SRV). In this paper, thrust coefficients and efficiency results obtained by different potential flow methods for the same SRV geometry at different advance ratios are presented. The methods...student report 2023

van der Vlugt, Joost (author)The angular momentum or swirl in the propeller slipstream is an energy loss. An effective method to recover the swirl and increase the propulsive efficiency is to use Swirl Recovery Vanes (SRVs). Former research showed an over-prediction in SRV thrust by a lifting line theory (LLT) model compared to wind tunnel experiments. The LLT model assumes...master thesis 2023

Tetteroo, Daan (author)All over the world, many offshore structures have been built in the last decades, both by the oil and gas industry and by the renewable industry. When these structures reach their end of life, they have to be removed. The removal is done in decommissioning projects. Many of those offshore structures are bottom founded. Of that amount, a big part...master thesis 2022

Ebbens, Elja (author)The advent of distributed electric propulsion aircraft concepts requires novel physics-based analysis methods for the modeling of the complex aerodynamic interactions between the closely coupled rotor, wing, and flap. For this purpose, the analysis tool Open Rotor-Wing-Flap Interaction Solver (ORWFIS) is developed with existing and novel low...master thesis 2022

De Ponti, Tomaso (author)This paper presents the design of an Incremental Nonlinear Dynamic Inversion (INDI) controller for the novel platform VSQP. Part of the identified challenges is the develop- ment of a model for the actuator effectiveness and lift especially as a function of skew, the newly added degree of freedom. In particular it is assumed that the actuator...master thesis 2022

de Vlieger, Tim (author)Offshore lifting operations must have reduced payload motion to increase safety and reduce operating time. When payload is retrieved from the splash zone to the deck, besides the crane block, no additional control can be applied on the underactuated system. Existing studies either assume more control over the payload or develop a control system...master thesis 2022

van Wilgen, Bert-Jan (author)This research examines the difference between two major component replacement strategies for the novel floating offshore wind turbines (FOWT), in terms of support vessel CO2eq emission and cost together with FOWT downtime. The first strategy is utilising a crane vessel to replace a component in offshore, this is called the heavy lift maintenance...master thesis 2022

Smorenberg, Marius (author)Climate change is triggering an ever-growing demand for renewable energy. The U.S. is still far behind Europe when it comes to offshore wind energy. They have made ambitious plans to reach 30 GW in offshore wind energy by 2030 while currently 42 MW is installed. One of the main challenges in the U.S. is the installation method since a...master thesis 2022

Buitelaar, Maarten (author)A dam-break wave can result in considerable damages and casualties. Events that can lead to such waves include dike and dam breaches, storm surges and impulse waves. Dutch history is familiar with a number of coastal dike breaches but also river dike breaches have occurred, resulting in dam-break waves reaching far inland. Beyond the Netherlands...master thesis 2022
