Luxemburg - Dredging group Jan de Nul welcomes three new water injection dredgers to its fleet. The vessels are smaller than traditional dredgers, and have high manoeuvrability and a limited draught.
Giovanni Venturi, is the first out of three to be delivered by PaxOcean Shipyard. It will be mobilised to its first project in Argentina. The other two Water Injection dredgers Henri Pitot and Henry Darcy are in the process of being converted and will be delivered later this year.
Contrary to the traditional dredging methods where sediments are mechanically transported, water injection dredging does not remove the sediments. Water is injected, sediments fluidize and nature takes care of the sediment transport. The sediments stay in their natural environment by only moving horizontally, just above the seabed. The process does not impact overlying water layers.
