Damen has shipped a fully customised cutter suction dredger (CSD) 350, to Brazil. The standard dredger was adapted to meet Brazilian naval requirements and received additional options as per customer request. Damen carried out the job very quickly: from contract signature to departure from the port of Antwerp, Belgium, in just under four months.

The CSD350 is the first stationary dredger Damen has delivered to Brazil. Many countries – Brazil not being an exception – have their own regulations for outfitting vessels. Therefore, the standard suction dredger from stock has been adapted accordingly. Moreover, the customer, Construtora Vale Verde, ordered a number of options. These include a non-return valve in the discharge pipeline, a wedge piece for shallow water dredging, a remote monitoring system, and a navigation package for maximising safety on the job.

The CSD350 has been designed to dredge inland waters at a dredging depth between 1 m and 9 m. It is fitted out with a 55 kW cutter head for breaking up compacted soils, and the inboard dredge pump is powered by a 447 kW diesel engine. For transport purposes, the dredger can be fully dismounted – quite practical considering that its first dredge job will be located some 500 km from its port of arrival, Vitoria.

The dredger left Damen Dredging Equipment in Nijkerk, the Netherlands, on several trucks – one for the main pontoon, one for both side pontoons and spuds together, one for the suction ladder, and one for the separate container shipping, the operating cabin, and various smaller items such as the navigation mast.

The dredger arrived in Brazil at the end of October, where it will be swiftly assembled by Damen, Vale Verde, and local agent Endratech engineers. With products being built in series – often for stock – Damen says it is able to guarantee the fastest possible delivery times for proven solutions.
