The jetty of the future: Reducing the environmental impact of a jetty platform structure by designing for reusability

The significant adverse contribution of the construction industry to greenhouse gas emissions and natural resource depletion has to be reduced. Regarding jetty platform structures, this challenge can be faced by designing for reusability, a promising concept for environmental impact reduction. However, this principle is not yet being widely...

Cohesive Sediment Erosion Induced By Coandă-Effect-Based Polymetallic-Nodule Collector: Small-scale experiments

The increasing demand for rare minerals, such as lithium, cobalt, and copper, driven by the growth of the world population and the transition towards sustainable energy technologies, has become a pressing concern. These minerals are crucial for electrifying the transportation sector through electric vehicle production and are in high demand for...

The influence of coarse content on the erosion of clay lumps during dredge pipe transport

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...

Modelling of high concentration fluid mud water injection dredging density currents

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...

Horizontal negatively buoyant jets in deep sea mining: The influence of initial concentration of discharged slurries on the spatial spread of turbidity currents

Recently, deep-sea mining has acquired renewed interest from commercial companies due to a rise in the demand of minerals and metals. Deep-sea mining is focussed on different minerals and rare earth elements found in the oceans that are increasingly used in the manufacturing of goods and products related to renewable energy. In order to collect...

Sediment traps: for reducing maintenance dredging costs in the port of Rotterdam

Regular maintainance dredging is a large expense to the Port of Rotterdam, therefore the installation of sediment traps is considered. By increasing the bathymetry locally, an increase of local accumulation is expected and a decrease deeper in the harbour basin. This thesis describes the functioning of sediment traps in a stratified tidally...

The hydrodynamics of an eco-innovative sediment reuse project in the Rotterdam Waterway: Gaining insight into the physics and the predictive capability of two operational hydrodynamic models

Phenomena like sea level rise, global warming and erosion together contribute to increasing flood risk in vulnerable coastal areas. As this flood risk increases, initiatives to mitigate the effects of climate change in the coastal zone are also increasingly sought. During recent years, the view that these measures should be circular has gained...

On the Effects of Fine Sediments in Mud Disposal Basins: Towards a better understanding of basin design by means of a numerical modeling study

Comparative feasibility study of a 30 MW disruptive floater solution with a 15 MW PivotBuoy and a benchmark 15 MW semi-submersible floater in the Bay of Biscay

This paper investigates the technical, life cycle, and economic feasibility of a 30 MW upscaled downwind turbine, comparing it to a 15 MW X1 Wind PivotBuoy downwind turbine and a benchmark 15 MW IEA Umaine VolturnUS-S upwind turbine in the 450 MW Sud de la Bretagne I wind farm site. The study is significant due to the rising energy demand, the...
