de Koning, Floris (author)This research focuses on a new system for nourishing the Dutch coast with sand, which utilizes semi-autonomous sailing barges and an electrical crawler to continuously replenish the beach. Yearly, the Dutch government grants contracts to nourish the Dutch coast with volumes around 10.000.000 m$^3$. The Dutch dune coast protects the low part of...master thesis 2023

Weyns, Julie (author)This thesis aims to investigate the effectiveness of the contained dredging system (CDS) in avoiding turbidity during dredging activities. Turbidity is a common issue that arises during dredging activities and causes the sediment to be suspended in the water column, which can have negative impacts on the environment. The CDS is a novel way of...master thesis 2023

Dijkstra, Jesse (author)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...master thesis 2023

Vehmeijer, Reinoud (author)Subsea rock installation is a process in offshore engineering where rocks are placed on the seabed or subsea structures using a fallpipe. An example of a subsea structure could be a cable or pipeline that must be protected. In this research, the main scope is rock installation for scour protection of the foundation of offshore wind turbines. As...master thesis 2022

Dobbe, Peter (author)In the field of mining and dredging engineering, oftentimes slurries are involved in transport. Understanding the behaviour of these slurries in a flow is important as the energy and water consumption need to be determined. The slurries have an interesting rheology due to the presence of clay. The rheological parameters cause the flow to be non...master thesis 2022

Ma, Sebastiaan (author)The Port of Rotterdam experiences large amounts of siltation from the upstream rivers in its basins and canals every year. Furthermore, container vessels increase in size every decade and therefore require a larger navigational depth. These two factors cause the yearly amount of dredged material to increase. Currently, mainly trailing suction...master thesis 2022

Ordeman, Sam (author)Digital Soil Mapping (DSM) of soil types in geotechnical project areas is a top priority. These maps are often used in decision making and can have significant consequences related to costs and risks. Usually, these maps are generated by digital soil models that interpolate soil types at known locations. In practice, conventional spatial...master thesis 2022

ten Brummelhuis, Erwin (author)Siltation of fine (cohesive) sediment in navigation channels and harbour basins may cause serious problems for the shipping industry. Intensive maintenance dredging is required to ensure safe shipping traffic. Conventional dredging methods are highly expensive, and therefore port authorities seek for more efficient solutions to reduce costs. One...master thesis 2021

Abrahimi, obaid (author)Particle-driven gravity currents cause major geological problems. Turbidity currents are highly erosive and can be damaging to structures on the sea bottom such as telecommunication cables. Understanding the mechanisms of sediment transport and deposition is required to predict the erosive powers of turbidity currents (and of the distribution of...master thesis 2021

van Ingen, Floris (author), Geleijnse, Jan (author), Curzi, Fabio (author), Kingma, Pieter (author)On request of Royal Boskalis Westminster N.V. a comprehensive research was performed regarding emission free maintenance dredging in a harbour environment. The project site is the Maasmond at the port of Rotterdam. It covers an area of almost 10 km2 and, on average, a monthly volume of 400.000 cubic meters of sediment needs to be dredged. The...student report 2021

Kalra, Siddharth (author)Dredging is an energy-intensive operation and, due to the nature of the process, there are large and rapid fluctuations in the power requirement. With the signing of the Paris Agreement, implementation of IMO 2020 and expansion of ECAs, the external pressures for the reduction of different emissions(CO2, SO<sub>x</sub>, PM, and/or NO<sub>x</sub>...master thesis 2020

Bedón Vásquez, Andrea (author)Turbidity currents are common in the waters around the world. They can be caused by earthquakes, collapsing slopes or other geological disturbances. However, turbidity currents can also be caused by deep sea mining activities. Deep sea mining is done with special mining vehicles. There are three main operations within this mining vehicle:...master thesis 2020

Dijkhuis, Koos (author)Dam reservoirs form a crucial part for human society storing water, controlling floods, providing hydropower, water for irrigation and drinking. Annually 1% of the worldwide dam reservoirs storage capacity is lost, caused by sedimentation. The inflow of sediment and reduction of flow velocity and turbulence in the reservoir pro- vides favourable...master thesis 2019

Heijmeijer, Oliver (author)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 < 1). However, modern day dredging processes are in the...master thesis 2019

Knook, Bastiaan (author)Our world is rapidly changing, leading to various technological achievements in diverse areas of expertise. Among the most evolving are autonomous robots, machines and vehicles, enormously extending human capabilities. While this trend became quite familiar for land-based vehicles, innovations in the underwater domain lag behind, mainly due to...master thesis 2019

Wijnands, Jasper (author)Manganese nodules have been lying on the deep sea soil for centuries before they became known. The first ones to discover the nodules were Murray and Renard, during their scientific cruise between 1872 and 1876 (Murray and Renard, 1876). The Clarion-Clipperton Zone, located between Mexico and Hawaii, appears to have a virtually inexhaustible...master thesis 2018

Stoter, Mike (author)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...master thesis 2018
