Abstract
A spud system for a dredging vessel with a longitudinal direction includes a spud carrier for mounting a spud therein in a vertical stance and which spud carrier is moveable with respect to the dredging vessel in a longitudinal direction for advancing the dredging vessel, a spud carrier drive system coupled with the dredging vessel and the spud carrier for driving the spud carrier with respect to the dredging vessel. The spud carrier drive system includes a hydraulic drive cylinder for controlling the position of the spud carrier. The spud system further comprises a hydraulic system comprising a parallel hydraulic cylinder in fluid parallel connection with the hydraulic drive cylinder and presstressing means coupled with a rod of the parallel hydraulic cylinder such that said rod is forced towards a central position.
