Currently, the foundation design of offshore wind turbines is based on a simple cantilever beam model with a mass representing the rotor and nacelle, or by making use of wind turbine simulation software such as Bladed, which are built for rotor design. The simple models are unrealistic since the dynamic interaction between the aerodynamic loads,...

There is nowadays an increased use of data, reaching 2.5 exabytes globally, and is expected to double every two years (Morvan, 2016). An enormous amount of data can now be generated, ranging from smartphones to sensors in machineries. However, most organizations are reported to be able to only create and store data, and creating added value from...

Sea level rise poses challenges to the tidal inlet systems of the Wadden Sea, including the barrier islands. If no measures are taken, the shorelines of the islands will retreat and the basins may drown. In the Ameland Inlet, the Boschplaat at the eastern tip of Ameland and Bornrif at the western tip of Terschelling are currently shrinking. <br/...

Composite structures are increasingly applied for their unique set of properties. However, their behavior is not yet fully understood, amongst others, due to complex interactions of failure modes. This research implemented a blended stress-strain and fracture mechanics based progressive damage analysis model, based on a Continuum Damage Model ...

Waves in coastal waters play a role in forecasting storm conditions, as boundary conditions for the assessment of coastal risk and in coastal structure design. Assessment of their impact can be made through numerical modeling. In a forecasting context, the CPU time of the wave model is decisive in its suitability. Recent years wave model...

This project’s research question is: How is society able to organize a mental healthcare system, that serves people’s individual care needs and is collectively economically viable? This research question regards a business model on a system level and the hybridity is reflected in the tension between the individual interest of fulfilling a care...

Two-phase thermal control systems are used for payloads that require temperature stability under high and fluctuating heat output. However, the complex interaction between the two phases in a flow makes it hard to predict the performance of such a system. The goal was to develop a numerical model able to predict the transient behaviour of such a...

In today ́s world, supply chains are facing a rising number of challenges due to a fast changing environment and business structure. Increasing globalization and market competition have forced companies to expand their business networks, moving from local to more complex and vulnerable supply chains. As the key pain point to supply chain...

The response of a shallow foundation has been investigated by numerical simulations in a series of 1g small scale tests using the Finite Element Method. In this numerical study, special attention has been given to the influence of soft boundaries as a measure to counteract boundary effects, since limitations of space were present in the...

The transition from a fossil based economy to a greener, bio-based economy remains challenged by the gap in technological maturity between bio-based processes and conventional fossil energy. Decreasing the price difference between fossil fuels and bio-fuels remains a major constraint. With 98% of the transportation sector now depending on fossil...

Offshore wind energy has very recently begun expanding into subarctic regions with seasonally ice-infested waters like the Baltic Sea. For offshore wind turbines with conventional support structures such as monopiles and jackets that are typically flexible and vertically sided, the phenomenon known as ice-induced vibrations can develop. In...

In 2016, Ford revealed its innovative concept 'Autolivery'. Nevertheless, the exact deployment conditions for the 'Autolivery' are not yet in place. In order to inhibit the collision space towards future implementation, a 'mobile locker' concept will come first, as seen in a roadmap. In this report, the potential of the 'mobile locker' service...

The COBRAcable project is one of the major interconnectors being constructed in the North Sea, connecting the Netherlands with Denmark. It is a 325 km submarine cable which will have the ability to transfer 700 MW. The importance of the interconnector is manifold: to facilitate the exchange of renewable energy coming from the onshore Danish...

Decision-theoretic planning techniques are increasingly being used to obtain (optimal) plans for domains involving uncertainty, which may be present in the form of the controlling agent's actions, its percepts, or exogenous factors in the domain. These techniques build on detailed probabilistic models of the underlying system, for which Markov...

The demand from the automotive industry for thinner, stronger and more ductile steels led to development of the so called Advanced High Strength Steels (AHSS). These new steel grades are produced at one of the hot dip galvanizing lines, “Dompel Verzinklijn 3” (DVL3), at Tata Steel IJmuiden. The annealing furnace in DVL3 consists out of a number...

Due to the shift in electrical energy generation from thermal synchronous generators towards various renewable sources, power system stability will become a more pressing issue in the near future. In this thesis, we explore possible improvements to the dynamic grid model currently used by TenneT TSO for large-disturbance stability studies,...

The Heineken supply chain goes from the production units, through local distribution centers, to the wholesale and retail customers in the market. Heineken Netherlands Supply is interested in bypassing the distribution center in Germany when possible. It is expected that these so-called direct deliveries have the potential to save on transport-,...

One of the phases of the installation of Offshore Wind Turbines is the installation of the foundation for the turbine. Herein, a monopile is one of the most frequently used foundation-types. This monopile is a high steel cylinder, over 60 meters high, which supports the wind turbine to the seabed. Currently, monopiles are lifted with large boom...

Fatigue is the most common source behind failures of mechanical structures. In order to study the phenomena, experiments have been performed by Lloyd's Register and other tests have been presented in literature. Performing real life fatigue experiments requires a long time, a considerable amount of money and it is size limited. <br/><br/>The...
