Verhoog, Max (author)
With the shift to renewable energy becoming more important than ever before and offshore wind farms being one of the sustainable energy resources available, many offshore wind farms are currently being built. <br/>One of the difficulties of these wind farms built with monopiles is that the monopiles and electricity cables must be protected from...

Jet trenching operations in sandy seabeds have been extensively studied and are well understood, offering a preferred method for offshore cable installation due to its relatively low environmental impact. However, the transition to clay seabeds presents significant challenges, demanding a deeper comprehension of jet trenching dynamics in...

The electric pulse fishing technique is no longer an option for fishermen. Therefore, they have to fall back on beam trawl fishing. This method has several disadvantages such as high fuel consumption and much soil disturbance. This system therefore deserves an investigation into improvement.<br/>There is various literature on interaction of...

Coastal communities around the world are facing significant challenges such as erosion, flooding, and storm surges. These issues highlight the need for nature-based coastal management solutions that can help mitigate the negative impacts of these events. Coastbusters Consortium developed such a solution in the North Sea. This solution is a...

When a ship reaches the shore, the water depth reduces and thus the under-keel clearance also reduces. The ship keel clearance influences the maneuverability of the sailing ship.<br/><br/>In this thesis project, the link between the fluid mud rheology and its density is first investigated. The exponential relation reformulated between the...

To meet energy demand towards a low-carbon future, the global market demand is growing for metals such as cobalt and nickel which are major elements in batteries. Polymetallic nodules, which are formed on abyssal plains at depths ranging from 4 to 6 kilometres and are distributed in high abundance on the top of the seabed, contains several times...

Understanding the erosion process of sand will help improve dredging projects. Pickup functions are used to predict the amount of sand that can be eroded by a flow with certain parameters. The most common functions that are used have been validated to data in the low velocity regime (θ &lt; 1). However, modern day dredging processes are in the...

Scarcity of (green) energy resources drives mankind further offshore and towards deeper waters. Protection of subsea infrastructure is of eminent importance in these environments. The key parameter to have a good control over the installation of rock is the falling time. For larger water depths up to 1200 meters, the accuracy of the falling time...

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...

Subsea rock installation is widely applied in the offshore industry and utilized for a wide range of purposes including but not limited to: pipeline protection, scour protection, insulation of pipelines, upheaval buckling prevention and seabed preparation. Tideway Offshore Solutions is specialized in subsea rock installation and currently...

The sliding force was a contributing factor to the displacement of caissons from the Kamaishi composite breakwater during the Great East Japan tsunami 2011 (Arikawa et al., 2012). The pressure reduction on the landward wall of the caisson due to non-aeration of the overflowing jet gives rise to an additional horizontal force which increases the...

In the offshore industry rock is used for different kind of applications, such as scour protection and pipeline protection. In deep water operations, but also increasingly in shallow water operations, use is made of the method by guiding the rock from the water surface to the seabed with a fallpipe. During a rock placement operation a current...

Royal IHC is exploring the possibilities of a subsea separation concept for its deep sea mining concept. The most promising concept from literature was the crossflow separator, this separation concept was further researched. This to have a look at the performance of such a crossflow separator and to find out what geometry is most suitable for...

The present thesis considers numerical computations of fully nonlinear fluid-structure interaction. The aim of the thesis is to establish a well validated fully nonlinear numerical wave tank for the simulations of complex fluid-structure interaction of moored floating offshore structures. The numerical computations are carried out using the...

A method is developed to assess the dynamic stability of a floating tidal energy platform during ballast operations. This method is applied to a tidal energy platform designed by Bluewater Energy Services B.V., showing the sensitivity of this platform’s dynamic stability during ballast operations to tidal current velocity, changes in lightship...
