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>...

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:...

The Offshore wind industry harvests energy in offshore locations, using large turbines to convert this energy to electrical power. The electricity is gathered and transported to shore via cables. These cables need to be protected from external hazards that could result in damages and thus economic losses. Generally the cables are buried in the...

This report describes and analyses small scale plough process. This research is initiated by Deltares and the Delft University of Technology as an experimental way to gain insight in the ploughing of the river bed in rivers. The main target of this thesis is to gather information on the plough process as applied in the maintenance of the Waal...

This study aims to improve the predictive capabilities of flow pattern and depositional behaviour of non-Newtonian, high concentration sand and fines mixtures. The depositional behaviour influences the geometry of the deposit and the distribution of sand and fines particles, which in turn influence the strength and consolidation performance of...

The subject of this master thesis is related to the passive suction under mud mats. Mud mats are used in the offshore industry to prevent structures from sinking in the soil after installation. If for some reason a structure has to be lifted, on the one side due to an installation error, on the other side due to removal the force needed to lift...

Erosion is a phenomenon present in several industrial processes. In dredging, the jetting of sand in drag heads erodes the sand bed. In construction of offshore infrastructure such as wind turbines, oil and gas production units, marine pipelines, erosion of material near the foundations can put the stability of structures at stake. Furthermore,...

Damen Dredging Equipment (DDE) has a quest to make their cutter suction dredger (CSD) and their DOP pump operable by everyone for every slurry type at the correct working point every time. To complete this quest, first a process status evaluating tool has to be developed which replaces the visual wear inspection. This thesis is the first step in...

As a result of past world wars and the dumping of munition at designated dumping areas, residual military ordnance are found on and in the seabed, especially in the Wadden Sea, North Sea and Baltic Sea. Of the estimated 1.5 million tons of military ordnance, roughly ten percent is classified as Unexploded Ordnance (UXO). There are three main...

For the installation of offshore windturbine pile foundations a dedicated subsea drilling tool has been developed. The installation forms part of the Wikinger windfarm project, located in the Baltic Sea. The main function of the tool is dredging up to a few meters of soil from the pile to allow for jacket installation. Next to this it is also...

The world is rapidly embracing networked technology and transitioning into one of hyperconnectivity, a term first coined by social scientists Anabel Quan-Haase and Barry Wellman. Increased connectivity provides benefits such as automation and, remote access and control of networks and equipment, thereby decreasing operational costs. Maritime and...

The significant growth in offshore wind activities in boulder clay areas requires suitable cable protection solutions. It is desirable to create a trench prior installation of the cable in order to guarantee the target depth of burial. Modern equipment of available on the market can be refined in order to create a reduced footprint, both...

An underwater slope can collapse by liquefaction, wedge failure or breaching. Breaching is the most unknown process and has a low predictability. Dredge mining is strongly influenced by the breaching process. If breaching can be accurately predicted, the efficiency of the dredging production can be maximised.It is the objective to know what...

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...
