Abstract

In a dredging operation, a cutting member (8) exerts a cutting force on a parcel (34) of pack bottom material. Thereby, in increase of the mutual distance of the bottom material particles (33) is generated, leading to a pore pressure decrease in the water field pores between said particles. By directing a water jet (30) towards said parcel of bottom material, a water flow is introduced into said pores thereby at least partly eliminating the pressure decrease and enabling a cutting operation with a decreased cutting force.
