A cable dredger DRH400 has been successfully used for a sand extraction operation along the Niger River.
The dredging system was commissioned by Matag, a Nigerian dredging company, interested in a product capable of increasing its extraction capacity.
The company was not only interested in expanding its market, but also in the normalization of the river.
The Niger River has a trend that changes according to the season; the depth increases by 8 meters in the rainy season. With the equipment previously in their possession, customers could only carry out dredging at certain times of the year, because the maximum depth reached was 12 meters.
To increase the productivity of sand extraction, Matag needed a dredger that was able to work constantly throughout the year, regardless of seasonality.
Dragflow supplied a DRH400 cable dredger configured to reach a depth of 35 meters, assembled with a DRAGFLOW HY400 hydraulic pump.
Thanks to this solution, the works were able to start successfully already at the end of July 2015. The customer said he was very satisfied with the production achieved and the efficiency of the DRAGFLOW product which far exceeded that of the previous dredger and allowed him to work uninterruptedly. The low cost was also a reason for customer satisfaction.
The solution offered by DRAGFLOW has made it possible to reduce production costs, without difficulty in operations, allowing the customer to dredge Niger up to a depth of 30 meters.
