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...

The quest for affordable renewable energy causes the need for bigger and more efficient wind turbines. To counter the problem of possible collisions between the growing turbine blades and the tower support structure, downwind turbines might be a solution. For this configuration, blade flexibility no longer forms a problem and besides that...

The submerged floating tunnel (SFT), also known as the Archimedes bridge or suspended tunnel, is a conceptual idea for a tunnel that floats in the water, supported by its buoyancy. The tunnel would be placed underwater, not too deep in order to avoid high water pressures, but deep enough for it not to be exposed to extreme weather conditions or...

The strive for cleaner energy sources is one of the most demanding problems the world faces today. The role of offshore wind in the energy transition is becoming increasingly relevant. One of the areas where the industry expects to reduce conservatism and uncertainty in design is the interaction of the foundations of offshore wind turbines with...

This thesis aims to gain insight into the global dynamic fluid-structure interaction response of a submerged floating tunnel (SFT) under the wave and current loading to enhance the design. To this end, the tunnel tube is modelled as a Euler-Bernoulli beam deformed in three directions (horizontal displacement, vertical displacement, rotational...

The purpose of this thesis is to formulate and test a computational method, based on linear complex modes, to calculate the dynamic response of a beam with a boundary dashpot excited by a non-linear response-dependent dissipative force. This impulse response method is a time-stepping method which iteratively approximates the non-linear force by...

Offshore wind energy is considered a necessary energy resource, that may stimulate the transition from fossil fuels. Following the successful development in Western Europe, offshore wind is quickly gaining momentum in the Asia-Pacific region. At variance with North-Sea based offshore wind turbines (OWTs), structures installed in the Asia-Pacific...

Crossing waterways is crucial to improve transport connections.<br/>In particular, new crossing methods are needed when the distance to be covered increases. Submerged Floating Tunnels (SFT) have been recently emerging as a cost-effective feasible crossing technique to connect fjords in Norway. However, only very little research has addressed...

Offshore production platforms in the North Sea must be decommissioned when production has ceased. A platform can be decommissioned using single lift with AMC (Active Motion Compensation) and transported to another desired location. However, the AMC is considered to be an expensive component. This thesisinvestigates a passive method of single...

With increasing evidence of human-induced accelerated climate change, the need of sustainable, non-polluting, energy sources becomes evident. Offshore wind generated electricity is currently one of the most promising sources of energy to create a sustainable global energy mix. The offshore wind industry has developed rapidly over the last years....

Hyperloop is a high-speed transportation mode which operates by sending magnetically levitated capsule-like vehicles through a near vacuum tunnel. Due to the reduced air resistance and friction, speeds exceeding those of modern aircraft should become possible. When the system is moved underground,<br/>the stability of vehicle vibrations may...

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...

One of the key aspects of sustainable development is to reduce the greenhouse gas emissions. In order to achieve climate goals, it is expected that wind energy will increase its importance in the electricity production. Offshore wind energy is expected to triple its installed capacity between 2020 and 2025. Several countries have expressed plans...

Wave barriers are a common mitigation measure when dealing with environmentally induced vibrations. These wave barriers generally consist of stiff vertical walls buried in the soil to impede waves on their path from the source to the receiver. The geometries of the wave barriers that are used in practice are very simple. More complex geometries...

Since the oil price collapse at the end of 2014, operators in the offshore industry experience a decline in revenues and a need for downsizing. Simultaneously, the wind industry is growing every year, as an increasing amount of companies and consumers are investing in green energy. This creates opportunities for Heerema Marine Contractors (HMC),...

Cyclic behaviour of soil has stimulated researchers for several decades to develop constitutive models that will be able make accurate predictions of soil behaviour and at the same time they will be simple to use. Constitutive models are considered to be more valid compared to empirical models, because they comprise by equations that have actual...

Shell is working on mono-diameter drilling (MOD). A MOD well, or MOD well section, has a (nearly) constant diameter over several sections. This is achieved by deploying expandable liners: a liner is lowered into position and is expanded by pulling an over-sized cone through it. This plasticly deforms the pipe, increasing its inner diameter to...

A reciprocity-based direct boundary integral method and indirect boundary integral method have been introduced and used to obtain the two-dimensional response of a cylindrical cavity embedded in a uniform elastic half space subjected to SH wave. By introducing free wave field and the actual field with a cavity, the key point to solve for...

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...
