van der Voorn, Jesper (author)On Saba, an island located in the Caribbean, a new harbour will be constructed. To protect coral reefs in the vicinity from light attenuation and sedimentation, it is important to monitor and predict the turbidity stresses caused by the dredging operation. In the early stages of such projects involving dredging operations, a common approach is...master thesis 2024

van Beek, Mats (author)In dredging and land reclamation, there are growing economic and environmental pressures to make beneficial use of fine-grained/cohesive soils. Due to these pressures, there is renewed interest in researching ways to optimise the beneficial use of fine-grained soils in dredging and reclamation.<br/>Stiff cohesive clayey soils soil break up into...master thesis 2023

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

van der Ven, Oscar (author)This study is the first to experimentally show two wave mechanisms regarding density wave amplification with long horizontal slurry transport. There is bed-driven and suspended-driven density wave amplification, in which the grain size determines which mechanism is dominant.<br/><br/>Density wave amplification in hydraulic pipeline transport...master thesis 2023

Stefanus Wicaksana Kurniawan, Stefanus (author)The feasibility of installing a suction system, which consists of a pump and pipeline for transporting sediment from the sediment trap to the reallocation site to complement the water injection dredging (WID) method is accessed in this thesis. The combination of a suction system and a water injection dredger is called central suction-WID system....master thesis 2022

Seegers, Daan (author)This thesis combines a high-tech, capital product, with servitization methods in order to create a product-service system. Servitization has allowed companies to align their interests and create a co-creation environment. The overall objective of this thesis was to find an improvement over the current service design of Beaver vessels. This new...master thesis 2022

Bakker, Mathijs (author)Due to the expected increase in coastal replenishment along the Dutch coastline, and the need to decrease pollutant emissions in the Netherlands and worldwide, the Autonomous Low Energy Replenishment Dredger (ALERD) is developed. The ALERD is a sustainable and cost-effective solution to perform coastal replenishment work along the Dutch...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

Nanninga, Stefanie (author)The amount of suspended sediment spill released during dredging activities in the Fehmarnbelt strait is monitored along the excavated trench to prevent negative effects on local ecology. Stratification due to the interaction of saline water from the North Sea and fresh water from the Baltic Sea forces bi-directional flow of the layer above and...student report 2021

Kroonenberg, Nick (author)The Autonomous Low Energy Replenishment Dredger (ALERD) strives to revolutionize the dredging world. The ALERD operates autonomously underwater, which saves energy during the dredging process and transit. Autonomous underwater operation drives the need of alternative energy facilities. However, due to the energy savings of dredging, alternative...master thesis 2021

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

Deuss, Bram (author)Sediment management is necessary to keep the Waal navigable. Sediment management in the Waal is carried out by both dredging and plowing of the river bed. By analysing historic data available at Rijkswaterstaat, the relation between the hydrograph and the amount of required dredging and plowing is investigated. Also the influence of the...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

van den Boogaard, Tim (author)Transportation of slurries over a distance has always been one of the main objectives for the dredging industry. To accomplish a transport, centrifugal dredge pumps and mixture pipelines need to be perfectly intertwined. For the centrifugal dredge pump, available information is relatively scattered or confidential. The performance of a...master thesis 2020

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

Veenman, Tjerk (author)In this study, the behaviour of fine sediment in settlings basins has been investigated. The understanding and prediction of return water quality assessments is improved by a comparative modelling study. Settling basins are required to decrease the exhaust of fine sediment particles when dredging and reclaiming land. Fine sediment particles can...master thesis 2020

van Halem, Pieter (author)This thesis introduces a new algorithm for optimising shipping routes within a dredging project. Highly dynamic and time-dependent hydrodynamic features influence shipping routes. Due to the complex interactions between the horizontal tide, vertical tide, stratifying forces, wind-driven forces, and limited water-depth, shipping routes were...master thesis 2019

Tims, Frido (author)Already since the start of civilisation dredging is carried out to create and maintain waterways and ports or to create new land. In recent times the scale of dredging and awareness of potential environmental impact of dredging have increased drastically. An often used dredging vessel is the trailing suction hopper dredger (TSHD). A TSHD pumps...master thesis 2019

Werkhoven, Jeroen (author)CSD spillage is defined as “any soil that is dislodged above the lowest cutter tip trajectory of a single swing, but is not sucked into the suction pipe”. In addition to higher energy consumption and material wear for delivering the targeted depth, spillage can lead to a variety of environmental issues. As of yet, no analytical model exists in...master thesis 2019

van Walt Meijer, Valerie (author)Companies (in general and in the dredging sector) are striving towards more sustainable operations. However, problems arise in the changing of current practices to operationalize sustainability goals in projects. The objective of this research is to describe the process of creating a sustainable operating environment for dredging and reclamation...master thesis 2018
