Delve into this issue’s articles about sliding slurry, a prevention checklist, sustainability advocate and value creator.



Which slurry transport regime should be used and why? Sape Miedema, Director of Studies of the MSc Offshore & Dredging Engineering & Marine Technology at TU Delft, selects one from five possible flow regimes thanks to its simple criterion: a ratio of the particle diameter to the pipe diameter.

A checklist of recurring issues extracted from the project experiences of industry professionals was prepared by the Dredging Management Commission (DMC) – a commission organised by CEDA – with the aim of successful dredging management by preventing these problems in future projects. Author Kathleen De Wit, Chair of the DMC and Principal Engineer at IMDC, explains the evolving checklist’s aim to continue growing the list of issues to one day eliminate them.

IADC speaks with Mark van Koningsveld – Professor Ports & Waterways at TU Delft – as he begins his new role as Professor Ports & Waterways at TU Delft and continues his quest for a sustainable dredging industry.
