Goense, Daniëlle (author)Cyanobacteria are photosynthetic microorganisms found in a variety of environments, including marine water bodies. Some species are able to perform biomineralization, producing minerals such as calcium carbonate (CaCO3) that may act as biocement. The biomineralization capability of cyanobacteria has already been explored in the development of...master thesis 2024

Uppenkamp, Gijs (author)Offshore wind farms are increasing in size and moving further from shore. Service operation vessels (SOVs) are used for offshore wind operation and maintenance (O&M) at these large far offshore sites. These large vessels typically have a smaller daughter craft (DC) on board that can assist them. This DC is however too small to provide the...master thesis 2024

Mezilis, Lefteris (author)The European energy transition policies aim to mitigate the effects of climate change by moving away from fossils and promoting both onshore and offshore renewable energy technologies. Although onshore renewables are driving the transition so far, policymakers believe that in order to achieve the targets, the power grid must have access to the...master thesis 2024

Ministeru, Alexandra (author)Floating Offshore Wind Turbines (FOWTs) pave the way to accessing deep water regions with abundant wind resources that are unreachable to bottom-fixed turbines. This technology is not widely deployed due to the increased cost of producing energy. A suitable control strategy can improve the power quality and extend the lifespan of the FOWT,...master thesis 2024

de Groot, Patrick (author)Current service and installation activities for offshore wind turbines are carried out by jack-up vessels, which eliminate wave disturbances to a large extent. The use of these vessels imposes several disadvantages, including high operational costs and the limitation of operating in restricted water depths. An alternative is a crane mounted on a...master thesis 2024

Dekkers, Wout (author)Steel is a widely used material in construction because of its availability, high strength-to-weight ratio, and recyclability. However, steel manufacturing consumes a lot of energy, and there is an increasing demand for more environmentally friendly building materials. Consequently, high-strength steel is becoming more popular as it reduces the...master thesis 2024

Ilardi, Davide (author), Kalikatzarakis, Miltiadis (author), Oneto, Luca (author), Collu, Maurizio (author), Coraddu, A. (author)Due to increasing environmental concerns and global energy demand, the development of Floating Offshore Wind Turbines (FOWTs) is on the rise. FOWTs offer a promising solution to expand wind farm deployment into deeper waters with abundant wind resources. However, their harsh operating conditions and lower maturity level compared to fixed...journal article 2024

Alcañiz Moya, A. (author), Monaco, N. (author), Isabella, O. (author), Ziar, H. (author)The growing global energy demand increases the need for renewable energy sources. This increase requires land to be occupied, competing with other activities such as agriculture and residency. In such a situation, renewable energy sources expand to other environments like the ocean. However, this new scene poses some challenges, such as the...journal article 2024

Tott-Buswell, Jacques (author), Prendergast, Luke J. (author), Gavin, Kenneth (author)Monopiles are the most common Offshore Wind Turbine (OWT) foundations due to their simplicity in design, fabrication, and installation. However, large new-generation turbines have led to significant changes in monopile dimensions, necessitating extensive finite element analyses and ground investigations to meet design requirements. While Cone...journal article 2024

Zou, Pengxu (author), Bricker, J.D. (author), Fujisaki-Manome, Ayumi (author), Garcia, Fernando E. (author)This research investigates the dynamic response of offshore wind turbine (OWT) systems subject to ice-structure-soil interaction (ISSI). To simulate the behavior of level ice sheets, a coupled approach involving the cohesive element method (CEM) and the finite element method (FEM) is applied. For soil-structure interaction (SSI), the Mohr...journal article 2024
