Damen DOP dredger shipped high up in the Andes to clean up reservoir in Peru

Posted on 15 April 2016

dws-damen-dop-dredger-anders1-770pxDutch ship builder Damen has delivered a DOP package for dredging a deep reservoir on the Rio Mantaro in Peru.

The various components of the modular DOP dredger 350L are limited in size to ensure all could be transported by road. The pontoons of the DOP dredger were made locally.

Deep reservoir
Reservoirs are notoriously tricky to maintain: from the surrounding area plenty of sand and silt is brought in by the river and the material deposits at the dam.

As reservoirs are usually rather deep, dredging can be quite a challenge.

For the Tablachaca dam in the Rio Mantaro another challenge was added; the location high up in the Andes required a modular dredger due to transport restrictions.

The dredging package included a DOP350L dredge pump which has a mixture pumping capacity of 2.400 m3/h as well as the diesel hydraulic power pack which drives the DOP submersible dredge pump, plus the hoisting winch.

This winch enables the DOP submersible dredge pump to be lowered on a cable to a dredging depth of -35 m. Moreover, a jet water pump unit was delivered for supplying the DOP’s suction head with pressurised water.

For all pumps suction and discharge piping was delivered for a swift start up.

The Damen Field Service crew had just returned from commissioning a cutter suction dredger in Algeria.

This customised Damen Cutter Suction Dredger (CSD) 500 had been delivered with a complete dredging package including a booster station and dredge piping enabling immediate start up.
