de Moel, Geer (author)Due to the rapidly growing offshore wind market, there is a high demand for capable wind turbine installation vessels. Current wind turbine installation vessels struggle with the installation of large diameter monopiles due to a lack of crane capacity and with the installation of wind turbine components at hub height due to a lack of crane...master thesis 2023

Bosma, Marten (author)Heerema Marine Contractors is assigned to execute the installation of 64 monopiles for the He Dreiht Offshore Wind Farm provided by Energie Baden-Württemberg (EnBW). The installation of the monopiles is done by means of a template structure. This template is specifically designed for this project and is installed on the seabed temporarily. The...master thesis 2023

Kementzetzidis, E. (author)At the end of 2019, the European Union (EU) put forward the European Green Deal to facilitate the technological progress necessary to achieve CO2-neutrality by 2050. Such a monumental achievement would require massive investments in infrastructure for the harvesting, storage and the transnational transportation of green energy. To date, the more...doctoral thesis 2023

Rojas, D. (author), Quintana Gallo, P. (author), Pürgstaller, A. (author), Bianchi, S. (author), Ciurlanti, J. (author), Pampanin, S. (author), Bergmeister, K. (author)This article presents a numerical study on the influence of the anchorage shear hysteresis on the seismic response of nonstructural components (NSC) connected to multi-storey reinforced concrete (RC) buildings, and of the anchorage itself. To cover a variety of different types of shear hysteresis shapes, this contribution considered the...journal article 2023

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

Aeroacoustics of Jet-Surface Interaction and Passive Solutions for Mitigating Jet-Installation NoiseRego, Leandro (author)Aircraft noise levels have been significantly reducedwith the introduction of high-bypass ratio turbofan engines, particularly jet noise due to turbulence mixing. This, however, has led to engines with larger diameters and a closer coupling between them and the airframe. As a result, interactions between the exhaust jet flow and the wing give...doctoral thesis 2022

Bron, Thijs (author)With the highly increased interest in offshore wind turbines and their technologies, the sector has witnessed rapid development in the past decade. For installed offshore wind turbines, there has been a lot of research conducted in the field of aero-, hydro- and structural dynamics, wind turbine-control, operation & maintenance, foundations...master thesis 2022

Blom, Ruben (author)The increased awareness of the negative consequences of man-made climate change has given rise to a fast growing offshore wind industry. Wind turbines become increasingly larger, and available locations for offshore wind farms are shifting towards deeper waters, where jack-up vessels can no longer be used for installation. Heerema Marine...master thesis 2022

Rosenboom, Bas (author)As the world economy and population grow, energy consumption grows too at a never before seen pace. Reducing costs and increased environmental awareness resulted in renewable energy sources being the fastest-growing sources in the last decade. Due to its high potential, many offshore wind turbines will be installed in the coming years. These...master thesis 2022

Hageman, Evelien (author)Over 5000 offshore wind turbine generators have been installed in the past decades. 80% of these wind turbines have a monopile foundation. Monopiles are hollow steel tubular piles with a diameter of up to 10m. The first phase of the monopile installation consists of the self-weight penetration into the seabed due to the mass of the monopile....master thesis 2022

Burggraaf, Diego (author)New trends in the offshore wind industry show that wind farms are being built further onto sea. This also means that turbines have to be installed in deeper waters resulting in new challenges for the offshore wind industry. The commonly used jack-up vessels have a limited operating depth and therefore floating installation vessels become an...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

Riemens, Boyd (author)Throughout history, different intraocular illumination methods for vitreoretinal surgery have been used and the most common limitations to the state-of-the-art intraocular illumination methods are the glare and reflections created by the illumination device and the relatively small illuminated area. A way to tackle these limitations could be by...master thesis 2022

Kleisiaris, Georgios (author)The need for sustainable solutions in the energy sector has led to the rapid increase of offshore windfarms around the globe. The areas with ideal soil conditions are gradually being occupied, pushing the offshore wind industry to search for methods of installing wind turbines in hard terrain. So far, the installation of monopiles in weak rock,...master thesis 2022

Tan, Tessa (author)Collective behaviour can be seen everywhere. It is the phenomenon where many individuals form a group together and act as a whole. These groups are mesmerising to watch, but we can also learn from them. The way these groups behave depend on how the individuals react to their local surroundings. Obtaining knowledge about this concept brings...master thesis 2022

KOURTIS, YANNIS (author)Pile tip damage due to impact with an object (boulder) during the driving process of monopiles is of main concern in the offshore wind sector. Numerical modelling could accurately describe this failure mechanism and used as a tool in practice but also for the development of appropriate guidelines. In this research project, dynamic Finite Element...master thesis 2022

Rego, Leandro (author), Avallone, F. (author), Ragni, D. (author), Casalino, D. (author)This paper investigates the mechanisms by which flow-permeable materials provide noise reduction in an installed jet configuration. Numerical simulations are carried out with a flat plate placed in the near field of a single-stream subsonic jet (M<sub>a</sub>=0.3 and M<sub>a</sub>=0.5). The trailing-edge region of the plate is replaced by...journal article 2022

Sánchez Gómez, S. (author), Tsetas, A. (author), Metrikine, A. (author)In this paper, the energy flux in a pile modeled as an elastic shell, is studied theoretically and experimentally. Based on this analysis, a new procedure is proposed to quantify the pile installation efficiency. This procedure is of importance for vibratory installation of the foundations of offshore wind turbines and it is believed to be...journal article 2022

Chen, Fuquan (author), Liu, Liyang (author), Lai, F. (author), Gavin, Kenneth (author), Flynn, Kevin N. (author), Li, Yida (author)Large-diameter monopiles are widely used as the foundation to support offshore wind turbines (OWTs) in shallow coastal waters. The benefits of small-to-medium diameter tapered piles have been reported in the past. The potential use of large-diameter tapered monopiles installed by impact driving to support OWTs is thus presented, and then...journal article 2022
