A cutter head arranged to rotate about an axis of rotation for removing material from a water bed comprises a base ring positioned respect to the axis of rotation; a hub positioned with respect to the axis of rotation; a plurality of arms extending between the base ring and the hub, the arms comprising a plurality of cutting tools; and a plurality of skirts, each skirt extending from one of the plurality of arms to the hub to form a closed surface between the arm and the hub from a distal end of the cutter head toward the base ring and ending with a side configured to be parallel to a backplate, leaving an open channel between the skirt and the backplate.

Cutter head with skirt

An assembly for being dragged by a vessel, wherein the assembly includes a filtering system and a fluidum guiding system, wherein the filtering system is suitable for filtering large volumes of fluidum, and wherein the fluidum guiding system defines a channel configured such that at least in a channel portion the current velocity of the fluidum guided through that channel portion is reduced downstream, and wherein the fluidum guiding system and the filtering system are mutually arranged such that current velocity of fluidum filtered in the filtering system is reduced for decreasing drag.
