SEPTEMBER 27, 2017 — Damen Shipyards Group is to provide Brazil’s Veracel Celulose, one of the world’s largest pulp producers, with a dredging solution to keep its maritime terminal accessible.

The solution was developed after a joint onsite evaluation of the terminal by Veracel and Damen and consists of a combination of a Damen type DOP 250 submersible dredge pump, and a type BS 250 booster station.

To improve the dredging efficiency the DOP Pump is equipped with a mining head fitted out with jet water nozzles, specially designed to loosen the sand. The pressurized water is delivered to the nozzles by a separate diesel driven jet water set. The DOP 250 pumps the dredged material over a distance of 450 m to the booster station, which than transports the mixture for another 800m to the desired discharge location.

In addition to the hardware, Damen delivered an extensive training and commissioning package carried out by one of Damen’s dredge masters assisted by the technicians of the Rio de Janeiro based Damen Service Hub. The training enabled Veracel to fully use and maintain its equipment within two weeks after delivery. The Service Hub in Rio ensures Veracel of 24/7 service to its equipment when needed.

Veracel has also ordered a production measuring unit (PMU_ as an add-on to the equipment. The PMU will enable Veracel to measure dry sand production in real time which will help to increase efficiency even further. The PMU has been enhanced to be used in Veracel’s remote equipment monitoring system.
