As a result of the worldwide population and welfare growth, the demand for energy (oil, gas and renewable sources) and raw materials increases. In the last decades, oil and gas are produced from more and more offshore sites and deeper waters. Besides energy, the demand for diverse metals and rare earth elements increases as well. These raw...

Piston diaphragm pumps are used world-wide to transport abrasive and/or aggressive slurries against high discharge pressures in the mining, mineral processing and power industries. Limitation of excessive deformation of the diaphragm is of utmost importance for eliminating fatigue failures of the diaphragm and thereby obtaining a high...

Deep sea mining activities require excavation of material at the sea floor, transport of the material from the sea floor to the sea surface and processing of the material afterwards. One way to transport the material from the sea floor to sea surface is by means of a riser with centrifugal pump booster stations. In this research it is...

3D CFD simulations, lab experiments and field measurements are used to get more understanding of the turbulent near field overflow dredging plume mixing. The focus has been on the most often used dredging vessel: a trailing suction hopper dredger (TSHD). Near field overflow dredging plume mixing is important because it determines the far field...

In dredging practice jetting is widely used for the excavation of soil. In this study the jetting process of a moving vertical jet in cohesive soil has been investigated. A number of jet tests were conducted on artificially prepared cohesive soil samples. The observed failure mechanisms are discussed. A calculation model to predict the jet...
