Modelling cutterhead/soil interaction for a cutter suction dredger in waves

7-8 November 2019. Ahoy, Rotterdam, the Netherlands

Blanken A and Los JG - Royal IHC, the Netherlands

Summary: Assessment of concept designs and design improvements of a cutter suction dredger often stumbles over the challenges of cutterhead and soil interaction. This paper will discuss how modelling soil interaction on the scale of a cutter head, rather than cutter teeth, enables complete system simulations.
