Young Author Award 2021 for Edwin de Hoog

0

The International Association of Dredging Companies (IADC) awarded the Young Author Award 2021 to Mr. Edwin de Hoog, research and development engineer at Royal IHC and doctoral student at Delft University of Technology.

The IADC Young Author Award is presented annually to “stimulate the promotion of new ideas and encourage young men and women in the dredging industry”.

The award is presented at top-notch conferences, with the 2021 winning young author selected from the acts of the CEDA Dredging Days, which were held virtually on September 28-29, 2021.

Mr. Edwin de Hoog was selected as the winner of the Young Author Award for co-authoring the research paper The relevance of time domain effects to the design and stability of hydraulic transport pipelines.

Traditionally, the design of a hydraulic transmission system has involved the analysis of the energy sinks and sources of a pipeline system. Specifically, the energy characteristics of the pump and transmission are balanced against the friction energy losses of the sludge in the pipeline.

Under field conditions, in dredging and mining pipelines, slurry dynamics are caused by fluctuating loads on the centrifugal pump, due to transient variations in the density of the mixture flowing through the pump. This research examines which time domain effects are relevant for such a temporal design methodology and discusses methods to study these effects in order to maintain certainty in pipeline throughput.

“The jury was of the opinion that the winning entry represents solid research that addresses the core of dredging activities,” said René Kolman, Secretary General of IADC.

“Building knowledge and optimizing techniques is something we have to do. But also something in which we must continue to invest, even at a time when dredging activities must be carried out in an increasingly large and complex context. “
