Laboratory setup to study cutting forces of blunt chisels
Dredging of rock using a cutter head as found on a cutter suction dredger will become increasingly more important as drilling and blasting is often prohibited. Understanding the cutting process and resulting forces on the chisels can lead to improved design and operational efficiency. The majority of experimental and numerical work performed considers rock cutting with an unworn or sharp chisel, often omitting the normal force. This article presents the linear rock cutting setup developed by Royal IHC to study the effect of a worn or blunt chisel geometry on the cutting forces, with the emphasis on the normal force.
Young Author Award
To stimulate the promotion of new ideas and to encourage the younger men or women working in the dredging industry and related fields, the IADC has instituted the IADC Young Author Award.

Numerical investigation of the head and unsteady flow characteristics of a dredge pump loading high-concentration sands
The head of a dredge pump is an important performance parameter and a strongly fluctuating head may affect the operating stability of the pump unit. The IADC Young Author’s Award paper analyses unsteady characteristics of pump performance to improve control of the dredge pump.
