Byishimo, Protogene (author)Growing markets for sustainable technologies such as solar panels, wind turbines, and electric cars require an enormous amount of raw materials that might not be available from sources on land. Exploitation of seafloor mineral resources could secure the supply of raw materials for the future. However, proposed deep-sea mining (DSM) systems will...master thesis 2018

van der Graaf, Onne (author), Hillen, Huub (author), van der Does de Willebois, Jeroen (author), Franken, Kris (author)The main goal of this project is to determine the optimal location for an OTEC installation with a minimum lifespan of 30 years off the coast of Barranquilla and to make an anchor mooring design for the floater on which this installation is located. Bluerise has identified an area near the coast of Barranquilla for which OTEC can be applied....student report 2018

Choi, Joshua (author)When dredging close to underwater sand slopes, steep slopes might form. In dense sand with low permeability this might lead to the so-called breaching process. The creation of a steep underwater slope marks the beginning of a breaching process. <br/>Pore volumes of densely packed sand tend to increase during shear deformations. This effect is...master thesis 2018

van Kreveld, Sylvia (author)Fatigue cracks could occur in the material of offshore and marine structures that are cyclically loaded. These cracks occur due to the cyclic stresses induced by the waves causing premature failure. Monitoring these fatigue cracks using a wireless system gives the opportunity to guarantee the integrity of the structure without manual inspection,...master thesis 2018

van Stappen, Jeroen (author)At large oceans depths (5000m) manganese nodules are formed, these are rock shaped objects that contain various rare earth metals, Royal IHC is currently developing equipment to bring these nodules to the shore. The nodules will be transported to the water surface using a Vertical Transport System (VTS).<br/><br/>In the VTS insight of the...master thesis 2018

Tielens, Sophie (author)Energy transfer between guides and bumpers duet to impulse loads<br/><br/>During reverse installation for executing platform decommissioning and removal projects, heavy modules such as the topside of an offshore platform are cut off their substructures and lifted back on the deck of crane vessels or onto cargo barges. To assure that the modules...master thesis 2018

Bijleveld, Floriaan (author)In the past decades the understanding of fracture of ductile material has increased substantially. Research has shown that the onset of fracture highly depends on the full state of stress inside the material. Better understanding of fracture resulted in more advanced and complex fracture models being conceived, allowing researchers to predict...master thesis 2018

van Dun, Luuk (author)In the transition from a fossil fuel driven economy to renewable solutions, the activities in offshore wind energy are growing. Operation and maintenance costs of offshore wind turbines are high, therefore alternative methods should be developed to reduce these costs. The replacement of heavy components, like a gearbox or a generator, is a...master thesis 2018

Droutsas, Athanasios (author)This report, which from now and onwards will be called the main body of the thesis, covers the core of the<br/>problem that has to be solved. Generally, the aim of this thesis is to investigate a laminated composite’s<br/>structural response, made of FRP, when its material properties are assumed stochastic instead of<br/>deterministic. The...master thesis 2018

van Vuuren, Frits (author)The Poineering Spirit is a heavy lift vessel that can lift offshore platforms in a single lift. Due to the waves, the vessel moves with respect to the platform. To make sure the vessel does not hit the platform, a motion compensation system is installed on the Pioneering Spirit. The maximum allowable vessel motions during<br/>the operation are...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

van der Helm, Jonathan (author)An enhanced methodology is proposed to include both the loading and the resistance of the upper stem (pipeline) in 18" ILT installation. Loading behavior and buckling capacity have been investigated. The upper stem behaves quasi-statically for all HMC projects, this corresponds to the current method of applying maximum found loads statically....master thesis 2018

Sharma, Sahil (author)<br/>The Offshore Industry is one of the most challenging industries. Offshore vessels must survive all weather conditions over its lifetime. In heavy storms, waves and ship motions become so large that water flows onto the deck, It is referred to as Green Water and is a serious challenge that needs to be considered in designing offshore vessels...master thesis 2018

Arntz, Ben (author)To meet the demand for renewable energy sources, large numbers of offshore windfarms are planned to be constructed in the near future. The majority of the foundations for these offshore wind turbines are large-diameter monopiles. The driving of monopiles into the seabed is conventionally done using a hydraulic hammer, this process is commonly...master thesis 2018

Nata, Spyridoula (author)In order for the offshore wind industry to be competitive, the cost has to be driven down. One of the major factors that contribute to the overall cost is the over-dimensioning of the substructure. The response of the structure under various loading conditions can provide valuable insight in the design phase so as to provide a structural design...master thesis 2018

de Zwart, Tim (author)As climate change seems to become more and more of a serious issue, a sudden surge of interest in clean and renewable energy sources is inevitable. Ocean Thermal Energy Conversion (OTEC), or the process of harnessing energy from the temperature difference between the warm upper ocean layer and the cold bottom ocean layer, is one of these...master thesis 2017

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

Middelweerd, luuk (author)In the Dutch coastal waters more and more wind turbines on monopile foundations are built. An important design parameter is the first natural frequency of the wind turbine. The first natural frequency is dependent on environmental conditions and different soil conditions such as scour. This research gives a better insight into the sensitivities...master thesis 2017
