van Vondelen, A.A.W. (author), Iliopoulos, Alexandros (author), Navalkar, S.T. (author), van der Hoek, D.C. (author), van Wingerden, J.W. (author)Operational modal analysis (OMA) is an essential tool for understanding the structural dynamics of offshore wind turbines (OWTs). However, the classical OMA algorithms require the excitation of the structure to be stationary white noise, which is often not the case for operational OWTs due to the presence of periodic excitation caused by...journal article 2023

Conde Santos Borba, P. (author), Sousa, Wilson C. (author), Shadman, Milad (author), Pfenninger, Stefan (author)During atypical droughts, power systems with a heavy reliance on hydropower risk increased greenhouse gas emissions if they are balanced with fossil-fired generation. This work investigates the role of offshore wind energy in reducing the vulnerability of power systems dependent on such hydrological patterns, thereby eliminating this emission...journal article 2023

Ubbens, Martiene (author), De Schutter, B.H.K. (author)Two optimization-based approaches are proposed to optimize the power routing and turbine setpoints of offshore wind farm (OWF) collector systems during cable outages. The open-loop control strategy assumes that the network can only be reconfigured at the beginning of the outage. In contrast, the receding horizon control strategy is deployed...conference paper 2023

ter Hofstede, R. (author), Williams, Gregory (author), van Koningsveld, M. (author)Incorporation of ecology and ecosystem services into marine infrastructural developments has gained interest over the last decades. Growing attention is given to combine the massive roll-out of offshore wind farms in the North Sea with reinstating the once rich but nowadays nearly extinct European flat oyster (Ostrea edulis). However, the...journal article 2023

Frontera Pericas, Pere (author)Floating offshore wind turbines (FOWTs) have the potential to harness wind resources in deepwater, which is so far prohibitive for conventional approaches. This, however, comes at a cost: the platform’s extra degrees of freedom (DoFs) introduce complex aerodynamic and hydrodynamic behaviours. Therefore, FOWTs must be accurately modeled to reduce...master thesis 2022

Castellino, Francesco (author)One of the main cost drivers of an offshore wind power plant are the support structures of the wind turbines, it is therefore of primary importance to optimize their design. Among the support structures available, the concept most widely adopted is the monopile-based support structure, whose design is often fatigue-driven. Offshore structures...master thesis 2022

Siderius, Eva (author)In 2050, the entire energy consumption in the Netherlands is foreseen to come from renewable sources. Offshore wind energy has the potential to enable this transition to a CO2-emission-free energy supply. Consequently, the development of offshore wind farms in the Dutch North Sea has been expanding enormously in the last decade. The Dutch...master thesis 2022

SIACHOS, KONSTANTINOS (author)The North Sea has significant potential in becoming a green energy hub, due to its remarkable offshore wind potential, and could therefore facilitate the energy transition to a net-zero energy system in Europe in the coming decades. In this transition, hydrogen is also predicted to play a key role, due to its ability to transport and store...master thesis 2022

Steggink, Maarten (author)To accommodate the growing demand for renewable energy, installation of new offshore wind energy capacity is increasing in many countries. New projects will be proposed for waters in which floating (sea) ice is a common occurrence in winter. Currently, projects remain limited to regions with mild ice conditions, such as the Southern Baltic Sea,...master thesis 2022

Bouwmeester, Boudewijn (author)The increasing global demand of renewable and clean energy has led to the exponential growth, development, and interest in the offshore wind energy industry and expansion towards earthquake-prone areas. Offshore wind turbine structures, typically supported by a tubular monopile foundation, are increasing in size to meet the increasing human...master thesis 2022

Saccone, Cecilia (author)The idea of shared mooring systems has been introduced in the offshore wind farm industry as an effort to lower the overall installation costs for floating offshore wind farms. The reason for building such plants is that using floating turbines allows them to move to deeper waters, reducing visual and environmental impact and allowing footprint...master thesis 2022

van der Spek, Joep (author)Reducing the levelised cost of energy is crucial to accelerating the energy transition. To develop offshore wind solutions in greater water depths, a floating solution is required. The time-domain simulations of these Floating Offshore Wind Turbines (FOWTs) under wind-wave misalignment used in research and industry projects are computationally...master thesis 2022

Vehmeijer, Reinoud (author)Subsea rock installation is a process in offshore engineering where rocks are placed on the seabed or subsea structures using a fallpipe. An example of a subsea structure could be a cable or pipeline that must be protected. In this research, the main scope is rock installation for scour protection of the foundation of offshore wind turbines. As...master thesis 2022

Delavinia, Dimitra (author)New offshore wind farms consisting of monopile-founded Offshore Wind Turbines (OWTs) are to be built in earthquake-prone areas. To design the monopile foundation and to accurately define the dynamic response of an OWT, the soil-monopile-superstructure interaction should be modelled properly. Due to the fact that the Three-Dimensional (3D) Finite...master thesis 2022

REPPAS, APOSTOLOS (author)Renewable forms of energy, and especially wind energy, have become an integral part of the energy infrastructure around the globe. However, the constant increase of installed wind capacity has put a strain on the selection of potential onshore locations for wind turbine installation. As a result, the wind industry is focusing on offshore...master thesis 2022

van der Stap, Florian (author)The increasing popularity of offshore wind as a result of the demand for renewable energy, forces the industry to consider the development of wind farms in sub-arctic areas. One of these areas is the Baltic Sea, where the potential for wind energy is very large, but which is also prone to the occurrence of ice. For the design of offshore...master thesis 2022

Sanders, Servaas (author)Wind energy has seen a transition from onshore to offshore in the last decades. The lack of space on land and up-scaling of turbine sizes led to the need of exploiting further away and harsher environments, where more space is available and there is arguably less of an impact on society. This together with a higher supply of wind resources has...master thesis 2022
