Lambach, Jan Willem (author)
The Meuse river has been made navigable for ships by the construction of a cascade of seven weirs. At only two weirs hydropower facilities exist. This implies the full hydropower potential of the Meuse cascade is not utilized. Rijkswaterstaat only provides additional permits when fish friendly turbines are used. By using pump-turbines the river...

The Ampelmann A-type hexapod platform is a motion compensating gangway system designed to transfer offshore personnel between a crew transfer ship and an offshore bottom founded structure. During operation, the platform is moved to compensate wave induced ship motion and create a still standing platform from which crew can safely transfer to the...

A dam including a tidal power station with pumping capacity is a new type of flood defence. The negative ecological impact normally associated with closure dams is partially mitigated by including a tidal power station in the structure. Water can move through the tidal power station resulting in a reduced tidal stroke at the created lake. This...

Ruiterkamp, Gilian (author)
In recent years wind turbines have become increasingly large to increase energy yield and cost-effectiveness. This has led to taller turbine towers, subjected to larger loads. As a result, Lagerwey turbines experience lateral tower vibrations at different resonance frequencies. These vibrations result in rotor speed measurement disturbances due...

A modular jackup, constructed from container-sized modules, offers mobility and design flexibility. The thesis aims to develop a fast and valid methodology for analyzing conceptual designs, focusing on the crucial connections between barges and couplings. Initial success is achieved through super elements in Finite Element Analysis, providing...

Offshore wind farms designed solely for hydrogen production are promising solutions for maximizing wind energy conversion, decarbonizing industries that cannot directly utilize electricity, and reducing the need for additional grid reinforcements. Furthermore, floating offshore wind turbines enable the capture of wind resources in deeper waters....

Offshore wind electricity generation will play a key role in the transition to a sustainable energy sector. In 2020, the European Commission presented their Offshore Renewable Energy Strategy which includes 300 GW of offshore wind capacity by 2050 (European Commission, 2020). This research focusses on the steel mass development of OWT structural...

Mols, Frank (author)
To meet the targets set at the Paris climate convention, a rapid decrease in the emissions caused by the process of extraction of fossil fuels is required. Especially offshore, where a grid-connection is often non-existent, having power supplied by local renewable energy sources with a variable power generation can potentially lead to problems...

de Waal, Wouter (author)
A large amount of offshore Oil & Gas platforms including ones located in the North Sea are reaching the end of their life-cycle. While there is already proven technology to remove topsides, the exact methodology to remove support structures is yet to be established. Especially, when it concerns large and heavy support elements of Gravity...

The work presented will investigate the usage of Oscillating Water Columns (OWC) in Coastal Structures to understand the functionality requirements and the viability of installing these devices in caisson breakwaters. The main focus is put on the efficiency of the design, to achieve optimum results and to avoid possible failure of the structure....

For marine structures subjected to combined wind and wave loads, predicting the long-term extreme response corresponding to a certain return period is an important aspect during the design stage. Generally, a full long-term analysis (FLTA) is recognized as a highly accurate method to determine the long-term extreme responses. FLTA integrates all...

Tjaberings, Jorick (author)
The ever-increasing size of offshore wind turbine substructures and the development of wind farms at sites further offshore, with greater water depths and with extremer weather conditions, raise logistical challenges that have never been faced before. Additionally, the offshore wind industry has to deal with governments cutting subsidies, small...

Ravndal, Bjarte (author)
The Bristol Channel has one of the largest tidal ranges in the world, with a mean tide of nearly 10.5 m at Avonmouth, and speculations on how to harness this energy date back well over a century. One method is tidal range by the use of tidal lagoons, which operates on principles akin to hydropower. The lagoon is essentially an enclosed reservoir...

Offshore wind is a rapidly maturing renewable energy technology and is expected to play a central role in future energy systems. It has the potential to generate more than 420,000 TWh per year worldwide, an amount approximately equal to eighteen times the global electricity demand today. While many of the most abundantly resourceful sites are at...

Floating bridges are found at locations where deep water must be crossed for a long distance, such as in Norwegian fjords. The superstructure of the existing floating bridges is usually constructed from steel. In a marine environment these bridges are exposed to dynamic wave loads. As such, the current floating bridges suffer severe damage due...

Renewable forms of energy, and especially wind energy, have become an integral part of the energy infrastructure around the globe. However, the constant increase of installed wind capacity has put a strain on the selection of potential onshore locations for wind turbine installation. As a result, the wind industry is focusing on offshore...

This research strives to contribute to the solution of the Amsterdam waste problem by improving the location determination of the various container types within the Centrum area. One of the modalities is an autonomous surface vehicle (ASV), and in this case, a Roboat. Since it is not possible to assign all demand to one modality, also trucks and...

Floating offshore wind turbines offer opportunities to harvest wind energy at deep-water locations, where the construction of fixed-base turbines is infeasible. The dynamic power cables, which interconnect turbines and transport the generated electricity, are under large dynamic stresses due to the environmental loads and the motion of the...

Wind turbines constitute a sustainable and effective solution for the production of energy using wind power. Offshore wind turbines are becoming of special interest. However, their design poses great challenges, since an offshore structure is subjected to combined wind and wave dynamic loading that is characteristic of the installation site and...

The Jones Act, limited US port facilities, and absence of Jones Act-compliant installation vessels pose significant challenges for offshore wind farm installations. These factors force contractors to explore new installation strategies, such as feedering. Feedering is an installation strategy where the wind turbine installation vessel remains...
