Wind turbine installation vessels (WTIVs) are ships that are specifically designed to install offshore wind turbines. These WTIVs have four or six large truss-like legs that are lowered towards the seabed by means of jacking systems. These jacking systems are regulated by control systems to ensure the leg is lowered with a constant velocity...

Cutter suction dredgers (CSD) are highly vulnerable to large wave loading due to their stiff, spud-based mooring. Many mitigations targeted at reducing the resulting stresses on the spud and other critical operating components have been proposed in recent years, most notably by adding a level of flexibility to the connection between the pontoon...

The development of floating islands is an attractive option to provide living/working spaces at sea, as it would be a more economical solution for many locations at sea where the water depth is high. However, large second-order wave forces cause the floating island mooring system to become expensive as the wave height increases. So, in many...

Estuaries are dynamic partially enclosed water bodies that are constantly or periodically influenced by the ocean and at least occasionally impacted by river discharge. This creates unique but fragile ecosystems that have to be managed with care in order to be recreationally, economically and ecologically valuable. One of the management issues...

Particle - particle interactions in graphene force charge carriers to behave as viscous liquid. In this report we model and study such a system in the framework of molecular dynamics. Two interaction regimes are studied, Dirac regime with negative interaction potential and Fermi regime with positive potential. We report on numerical stability...

Coastal regions are more and more affected by changes in water levels, storm patterns etc. owing to climate change. Nourishments and other human interventions constitute common practice in order to maintain and secure these areas. However, many aspects, especially the hydrodynamics, are not yet fully understood due to the complexity of the...

In this thesis the differences between the monohull and semi-submersible are investigated. For a general heavy lift crane operation and its operational profile, the difference is performance and total cost are calculated. These are used to determine the turning point, the point where the semi-submersible is more favourable for a heavy lift crane...

Many small island developing states (SIDS) are among the most vulnerable to climate change (e.g. sea level rise) and seasonal to inter-annual climate variability, and subsequently experience flooding due to swell waves and wind waves, coastal erosion and salinisation of freshwater lenses. To counteract this, reef flat mining for sand and...

Rapid hydropower development is taking place in the Mekong river, which is expected to change the natural river regime. Because of the ecological and economical importance of the Mekong delta, the effects of these changes could have large consequences in the delta area. This research focuses on the hydrodynamical processes and assesses potential...

Airborne Wind Energy (AWE) is a field of engineering that utilizes tethered aircraft for the generation of electrical power. The potential for the application of AWE in deep-water offshore environments on top of floating foundations is enormous. Where conventional wind turbines would require a very stable platform to reduce motions at the...

Wave runup is generated by energy which remains after wave breaking and travels farther to the coast in the form of a bore. It can be seen as a thin wedge of water running up the beach face (Brocchini and Baldock, 2008). Under storm conditions runup is responsible for beach and dune erosion and accurate runup predictions are therefore required ...

Estuaries are complex systems that show a variety of hydrodynamic conditions. These conditions are influenced by bathymetry, geometry, climate characteristics, interacting fresh and salt water flows, and mixing effects caused by winds and wind-waves. The interaction between fresh and salt water flows in combination with mixing effects caused by...

The use of the detached offshore submerged breakwater (SBW) for coastal protection has an increasing popularity due to its low aesthetic impact on the natural environment. Submerged breakwaters however have only rarely been adopted and therefore its efficacy remains largely unknown (Ranasinghe et al. 2010). Shoreline erosion has been reported in...

The Ocean Cleanup’s goal is to extract, prevent and intercept plastic pollution by initiating the largest clean-up in history. It aims to achieve this by installing a large moored floating barrier, which passively concentrates the plastic debris using the ocean currents. In this thesis an alternative to this concept is developed and evaluated....

Double Master of Science in Hydraulic Engineering (Civil Engineering and Geosciences) and Applied Mathematics (Electrical Engineering, Mathematics and Computer Science) - It is of importance to know how the water is behaving in rivers due to the dangers, such as flooding and eroding of land, it can bring with it. Present day we are still...

The decommissioning market expenditure is expected to grow further in the years to come due to increasing number of platforms that near the end of their production cycle, mainly being xed steel structures (<4,000 [Te]) positioned in shallow waters (30 to 75 [m]). The risks of such operation emerged the need for semi-submersible, heavy-lift...

In this thesis, a method was developed, with which the infragravity waves and morphological changes of a sandy foreshore are included in the calculation of the probability of dike failure due to wave overtopping. Constructing a natural foreshore in front of the dike can be an attractive and innovative method to decrease the failure probability....

Heerema Marine Contractors (HMC) operates several crane vessels, barges and tug boats for the transportation, the installation and the removal of offshore facilities. To achieve safe and successful projects, the accurate prediction of vessel motions is of great importance. Vessel motions are calculated on the basis of wave energy spectra and...
