Study of slurry transport characteristics in a jet pump

In this study, the computational fluid dynamics (CFD) analysis method was used to simulate the mixing and transportation  characteristics of water and mud in a jet pump. By observing the fluid mixing law in the mixing chamber, throat and other structures,  the internal flow field distribution of the jet pump under different working conditions was compared and studied. As a result, the internal flow details and operation performance curves of a certain size jet mud pump were obtained. It provides theoretical support  for the optimisation design of a slurry jet pump in dredging engineering.

The Fehmarnbelt tunnel trench dredging project

A fixed and direct transport connection between Scandinavia and Central Europe has been an enduring vision for many decades. This vision is about to be realised with the construction of the Fehmarnbelt Fixed Link, an 18-kilometre-long immersed tunnel between Rødbyhavn in Denmark and Puttgarden in Germany. When it opens in 2029, the tunnel will be the longest immersed tunnel in the world combining a dual railway and motorway connection. This article provides insight into the improved dredging equipment used and the methodology specially adapted and further developed to the project’s requirements.

LIFE MARINAPLAN PLUS Project: Sustainable marine and coastal seabed management

In June 2019, the research team of the LIFE MARINAPLAN PLUS project began operating the first-of-a-kind demonstration plant installation at the harbour entrance of Marina di Cervia (Italy). Fulfilling the project’s objective to apply at industrial scale a reliable technology for the sustainable management of sediment in marine infrastructures, this technology prevents harbour silting through the use of submerged devices called ‘ejectors’ installed on the seabed.
