Belgian ports simultaneously dredged
Jan De Nul has sent its two trailing suction hopper dredgers to the ports of Antwerp and Zeebrugge to work on simultaneous dredging projects.
Tristao da Cunha and Sanderus are among its newest generation of ultra-low emissions vessels *ULEvs) Jan De Nul says, thanks to a filter system that reduces exhaust gases and captures nanoparticle emissions.
”The technology complies with the stricter European EURO STAGE V directives regarding emissions on land and waterways,” the company says. ”This makes the vessels the optimal equipment for this dredging project, in which the Flemish Government stipulated that dredging operations must be sustainably executed, with strict criteria on NOx-emissions.”
Jan De Nul says its technology was inspired by the Swiss government, which stipulated that all exhausts in the tunnels going through the Alps must be filtered to a minimum to protect workers in the tunnels.
“The bi-phased filter system on board the ULEvs does the same thing – it reduces NOx emissions by means of a catalyser up to 99%, and it filters the emissions of nanoparticles to levels lower than a Euro 6 truck,” the company says.
Because Jan De Nul’s vessels often work in ports, on rivers and near the coast, emissions inevitably affect people living nearby. For this reason, all new vessels since 2015 have been equipped with this technology.
