Thangaraju, Deepakraj (author)To increase the benefit of wind energy, the next generation wind turbines are becoming larger and are moving into deeper waters. This significantly increases the size and weight of the corresponding monopile support structures. In current practice, the majority of monopiles are installed using jack-ups or floating vessels using so-called...master thesis 2021

Liu, Carmen (author)One of the challenges associated with offshore wind turbine installations is the mating phase. Aligning a transition piece onto its substructure under offshore conditions is a complicated and time-consuming procedure. Another issue found in a number of commissioned offshore wind turbines is related to the sustainability of the connection between...master thesis 2021

Symes, Patrick (author)This thesis aims to provide insight into the conceptual design phase of Tetrahedron B.V. with regards to buckling stability. Currently, Tetrahedron B.V. assumes an effective length factor of one for determining the cross-section profiles of the Tetrahedron Crane. In this thesis, Euler-Bernoulli beams are used to model every member of this crane,...master thesis 2020

Bots, Michiel (author)Floating offshore wind turbines can only withstand a limited amount of (heave) motions before the equipment fails. In order to reduce the heave motion, the DeepCwind floater for offshore floating wind turbines makes use of heave plates. This semi-submersible floater consists of three cylindrical columns with a heave plate attached to the bottom...master thesis 2020

Lammers, Anneli (author)Van Oord is active in the subsea cable installation industry and executes most of their cable lay projects with their cable laying vessel: The Nexus. In this thesis the focus lies on the normal lay phase of the cable installation, which comprises the phase when the vessel is pulling out the cable and putting it down on the seabed following the...master thesis 2020

Sonneveld, Michelle (author)As buildings get taller and lighter, structural engineers are increasingly faced with the consequences of the dynamic response of high-rise buildings to wind. Damping is an important property for the dynamic response of high-rise structures, but is a combination of many mechanisms, which makes it a complex phenomenon to account for in the...master thesis 2020

van Essen, Thijs (author)Offshore wind energy is one of the solutions to meet the growing demand for renewable energy. The offshore wind turbines producing this energy keep increasing in size and, as a result, the monopile foundations are becoming larger and heavier. The traditional jack-up installation vessels have limited crane capacity and many of these vessels are...master thesis 2020

Kunicka, Ewa (author)In this research project, an assessment of an abatement measure for mitigating railway induced vibrations is carried out. Ground-borne vibrations, which are primarily generated due to wheel-rail interaction, may also result in ground-borne noise in the buildings located in vicinity of railway tracks. An example of adverse environmental impact...master thesis 2019

de Bruijn, Janno (author)In the Netherlands there are many bridges that crosses waterways, which are key nodes in the transportation system. The safety and integrity of these bridges is nowadays assessed by (visual) inspections at regular intervals. This approach cannot provide information about damage development in between inspections, leading to potential failure or...master thesis 2019

Anwari, Sherzad (author)The oceans, which cover nearly 70% of the earth’s surface, can be considered as an inexhaustible energy source for renewable electricity due to its size and predictability. One way to capture ocean energy is by harnessing the energy produced by waves at sea, by means of devices called wave energy converters (WECs).<br/><br/>Delft University of...master thesis 2019

Gijsberts, Bart (author)In this thesis, an alternative cable lay system was designed that can be used on existing non-cable lay vessels. This design is conceptualized and analyzed for a specific market, following the steps in the engineering design process. The technical and economic analysis investigates the feasibility and competitiveness of the new cable lay system....master thesis 2019

de Visser, Rolan (author)After the construction of the Grevelingendam (1965) and Brouwersdam (1971), the tidal movement in Lake Grevelingen disappeared. This caused a deterioration of ecological parameters influencing the surrounding flora and fauna and consequently a decline of the water quality set in. Amongst others, Rijkswaterstaat and the provinces of Zeeland and...master thesis 2019

Lee, Jaehyeun (author)Fatigue is often a governing design factor for offshore wind turbines. Since the design of offshore wind turbines includes conservatism, the actual accumulated fatigue damage can be lower than what the turbine is designed for. In this case, the operator can make a decision on life time extension of existing wind turbines. Therefore, it is...master thesis 2019

Chan Chow, Megan (author)Offshore floating wind turbines are one of the newest technologies in the renewable markets today. The world’s first floating wind farm, the Hywind Scotland Pilot Park, was commissioned in October 2017 and has been competitive with fixed bottom offshore wind turbines. There is a global push to make more renewable energy available, but less...master thesis 2019

Yuan, Jun (author)The hyperloop system is a new transportation mode, which consists a magnetic levitating capsule-like hyperloop pod and a vacuum tube. Due to small air hindrance, the hyperloop pod is conceived to have a maximum speed of 333 m/s. If such a hyperloop system is to be built underground in soft soils, the hyperloop speed can easily reach the wave...master thesis 2018

Kagie, Anton (author)A Cutter Suction Dredger (CSD) is a vessel that is used to cut hard soils with precision. It is moored stiffly through a spud pile while the soil is being cut. This, in combination with wave loads, causes the whole system to be dynamically challenging and nonlinear. Previous attempts to model a CSD in operation have been limited to the frequency...master thesis 2018

Atkinson, Rob (author)Delft Offshore Turbine (DOT) is developing a new offshore wind turbine, including, amongst other innovations, a slip-joint that connects the turbine tower and monopile foundation. The slip-joint is a mechanical, friction-based connection that provides many advantages over a bolted or grouted connection, such as the ability to support high loads,...master thesis 2018

Daamen, Joris (author)Trends towards higher capacity offshore wind turbines (OWTs) and deeper offshore wind farm sites, make wave-induced vibrations more dominant in its design. During idling phases of these next-generation OWTs, additional damping is required. This can be achieved through dynamic vibration absorbers (VAs), i.e. dampers. More importantly, wave...master thesis 2017

Faragau, Andrei (author)When a source moves along a straight line with constant velocity and acts on an inhomogeneous medium, energy is radiated away from the source. This phenomenon is referred to as transition radiation. The energy radiation can also be generated by the change of velocity or path of the source (radiation in a non-uniform motion), as well as when it...master thesis 2017
