(author)Large-scale offshore wind energy developments represent a major player in the energy transition but are likely to have (negative or positive) impacts on marine biodiversity. Wind turbine foundations and sour protection often replace soft sediment with hard substrates, creating artificial reefs for sessile dwellers. Offshore wind farm (OWF)...article 2023

Gusatu, L.F. (author), Zuidema, C. (author), Faaij, A. (author)Growing EU energy ambitions in the North Sea region are urging for an accelerated deployment of large-scale renewable energy (RE) infrastructure, with offshore wind farms (OWF) playing an essential role. However, implementing the current EU targets is limited by the competing spatial claims between existing sea uses and OWFs and uncertainties...article 2022

(author), Wilts, F. (author), Neumann, T. (author), Potenza, G. (author), Calabretta, F. (author), Fioretti, F. (author), van Wingerden, J.W. (author)The concept of wake steering on wind farms for power maximization has gained significant popularity over the last decade. Recent field trials described in the literature not only demonstrate the real potential of wake steering on commercial wind farms but also show that wake steering does not yet consistently lead to an increase in energy...article 2021

Wagenaar, J.W. (author)This chapter addresses met mast measurements for wind turbine wake research, where we tackle the matter by posing and answering three questions. By asking ourselves what the value is of met mast measurements for wake/aerodynamic research, we describe how met masts can be and have been used in aerodynamic research, accompanied by a number of...bookPart 2021

(author), Koomen, L. (author), de Ridder, E.J. (author), Serraris, J.J. (author), Struijk, G. (author)This paper describes the SPOWTT project. The intention of this project was to understand how sailing by crew transfer vessel (CTVs) to offshore wind farms affects the mental and physical wellbeing of individuals on board. The focus was on quantifying this impact, understanding the key drivers, with an aim to ensuring personnel can arrive to the...article 2021

Kanev, S. (author)Wake redirection is a wind farm control strategy that aims at increasing the overall power yield of a wind farm. It involves intentional misalignment of the rotors of upstream wind turbines with respect to the wind direction, thereby diverting their wakes aside from downstream turbines. The yaw misalignment angles are typically optimized using...article 2020

Kanev, S.K. (author), Bot, E. (author), Giles, J. (author)Active wake control (AWC) is a strategy for operating wind farms in such a way as to reduce the wake effects on the wind turbines, potentially increasing the overall power production. There are two concepts to AWC: induction control and wake redirection. The former strategy boils down to down-regulating the upstream turbines in order to increase...article 2020

Stock Williams, C.F.W. (author), Krishna Swamy, S. (author)Offshore wind farm managers and schedulers need to manage large numbers of wind turbine visits every day, in order to: repair minor faults; conduct inspections; and perform scheduled service operations. Daily schedules form a choice of which maintenance activities to conduct, taking account of: constraints on weather conditions, shifts, vessel...article 2019

Kanev, S. (author)Active wake control (AWC) is an operational strategy for wind farms that aims at reducing the negative effects of wakes behind wind turbines on the power production and mechanical loads at the wind turbines' downstream. For a given wind direction, the strategy relies on collaborative control of the machines within each row of turbines that...article 2019

Kanev, S.K. (author), Savenije, F.J. (author), Engels, W.P. (author)The wind turbines within a wind farm impact each other's power production and loads through their wakes. Wake control strategies, aiming to reduce wake effects, receive increasing interest by both the research community and the industry. A number of recent simulation studies with high fidelity wake models indicate that wake mitigation control is...article 2018

In order to reduce the O&M costs and to guarantee safety and wellbeing of the maintenance technicians, for each individual wind farm an optimal set of support vessels and access systems should be selected. This selection should...conference paper 2016

(author), Dekeling, R.P.A. (author)Concern exists about the potential effects of pile-driving sounds on fish, but evidence is limited, especially for fish larvae. A device was developed to expose larvae to accurately reproduced pile-driving sounds. Controlled exposure experiments were carried out to examine the lethal effects in common sole larvae. No significant effects were...conference paper 2016
