International Dredging Review

International Dredging Review
MENUMENU

The Central Dredging Association (CEDA) has been conducting a year-long series of webinars on Dredging Equipment and Technology. The webinars focus on the Cutter Suction Dredge and the Trailing Suction Hopper Dredge. All six in the series have been presented by two internationally renowned authorities on the subject Dr. Cees van Rhee and Dr. Sape Miedema both of the Delft University of Technology in the Netherlands.

The series is organized in two parts com-prised of two basic level presentations on the working principles of these two dredgers and four advanced level presentations on more specific aspects. The first two basic level presentations in Part 1 took place on May 12 the “Work-ing Principle of the Cutter Suction Dredge” and on September 14 the “Working principle of the Trailing Suction Hopper Dredge” both presented by Cees van Rhee. 

Part 2 consists of four advanced level webinars. One entitled “Production estimation based on specific energy in sand clay and rock” was given on October 19 by Sape Miedema and the second (November 15) on “The sedimentation process in a TSHD” by van Rhee. The next two in the series were presented on November 22 “An overview of slurry transport models” and on December 6 “Flow regimes diagrams in slurry transport” both presented by Miedema. 

Dr. Cees van Rhee is an engineer and full Professor of Dredging Engineering at the Delft University of Technology. He is the author of numerous scientific publications with a specialty in the modelling of highly concentrated sediment water flows and high velocity erosion of granular sediments.

Dr. Sape Miedema is Director of Studies of the MSc Marine Technology as well as Associate Professor of Dredging Engineering at the Delft University of Technology. His expertise is in soil mechanics and soil cutting hopper sedimentation mechatronics applied thermodynamics drive system design principles mooring systems and mathematics. His research focuses on the mathematical modeling of dredging systems like cutter suction dredges hopper dredges clamshell dredges backhoe dredges and trenchers.

All CEDA webinars are available free of charge on the website of the Central Dredging Association (http://www.dredging.org/content/content.asp?menu=1000_94).
