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.
