DOP Submersible dredge pumps

The crane-mounted DOP pumps to a booster station

PROJECT SUMMARY

Location: Terminal marítimo de Belmonte, Brazil

Period: start Q2, 2017

Product type: DOP250 with sand production head

Contractor: Veracel Celulose

Brazilian sea port maintained using DOP250

On the Brazilian South Atlantic coast, the continuous transport of sediment threatens the accessibility of the Belmonte terminal. To tackle this problem, the owner has acquired a DOP250 submersible dredge pump. The DOP is attached to a crane, which is located at the end of the Pier. The DOP is powered by a dedicated diesel hydraulic power pack.

DOP250 stored on pier with crane in back ground.

The dredging depth is approx. 10 m. A jet water assisted exchangeable suction head boosts the DOPs sand mining performance. A separate jet pack, being a containerized diesel-driven jet water pump, is located next to the crane on the Pier.

The overall length of the discharge piping is over 1 km.



Due to the long discharge distance – some 1.3 kms – a land-based booster, type BS250, is added in the discharge piping. Working together the DOP and booster easily reach the discharge area for storage of the dredged sand.

The discharge of the dredged mixture.

The DOP and booster have been delivered including all connecting piping and training. The design of the project lay out involved close cooperation between Damen engineering van Veracel Celulose, which has resulted in the turn key delivery of the entire dredging system.

DOP250 lowered into the water.
