The ROEROORD sand-wheel pontoon was initially built for the deepening of the Zandmaas. The installation on board this pontoon removes the sludge and overly coarse materials from the sand and gravel dredged up from the bottom of the Meuse. The remaining product is loaded onto inland navigation vessels, which take it to the classification facility of Martens en Van Oord in Moerdijk for further processing.

A special feature of the ROEROORD is that it has been made suitable for explosion-proof dredging. Explosives were found in various locations while dredging the Meuse. Due to finding these conventional explosives, Martens en Van Oord developed a unique secure working method: the ROEROORD sand-wheel pontoon was converted and secured for this task. The sand drawn up from the bottom is transported through a reinforced pipe and sieved. A magnet is used to remove all the parts containing iron, including explosives. These are collected in a secure container and removed.

Because of this working method, Martens en Van Oord is certified under the WSCS-OCE. By obtaining the certificate, Martens en Van Oord can from now on perform dredging work safely in ‘suspect’ areas using the ROEROORD sand-wheel pontoon.
