Damen Shipyards Group has provided a DOP Dredger component package to SPI Servicios Portuarios Integrados of Mar del Plata port in Argentina, which will initially be used to dredge underneath a 150m floating shiprepair dock, which the shipyard needs to keep operational full-time, so the dock must remain in place during dredging activities.

The shipyard will assemble the dredger, the first locally-built dredger in Argentina, which as well as dredging under the dock will be made available for other infrastructure activities around the port in Mar del Plata and Caleta Olivia and on the banks of Arroyo La Cruz in Campana, Buenos Aires. The shipyard operates two other docks, and because the dredger is demountable for transport over long distances by road, it can be relocated where needed.

The DOP Dredger, type DD250, is a standard dismountable dredger designed to remove silt or sand from -2.5m to -15m dredging depth. It pumps some 1.250 m3/h using a Ø250 mm pipe line. The total installed power is 395kW. Shipped in only a few containers will be the operating cabin, the power pack, a jet pack as well as the various hydraulically driven winches. The standard equipment base has been modified to meet the shipyard´s needs. The DOP Dredger DD250 will be able to work in two configurations: with a cutter head targeting compacted soils and with a jet water assisted mining head for easy pumping away loosened bulk sediment. The compact jet water assisted head enables the DOP pump – which is mounted at the bottom end of the ladder – to reach the pit at 11m depth below the floating dock. Due to continuous tidal movement and traffic in the busy post, each year a layer of silt of some 30-40 centimetres is built up underneath the dock.

Mr Ciceri, SPI’s Purchasing Manager, said: “We are happy to build the first dredger in Argentinian history. The dredger will ensure our independence so that we will be able to operate our floating dock more efficiently.”

The dredger will be operational early next year.
