NAVILUS Marine Gearboxes for Dredgers

Information material

Customized solutions for dredger

Suction hopper dredgers are used for the recovery of raw materials and for extension of water shipping lanes. Driven by their own propulsion system the dredger move to the extraction area where they start removing dredged material from the water bottom or waterway beds. The material is pumped into the ship´s hold. The water that was separated from the dredged material is returned into the water. When it comes to discharge the dredged material is flushed out in the same way.

FLENDER gearboxes are avaliable for both drive systems, the drive system for the dredger pumps as well as the drive system for the propulsion system. Based on decades of experience FLENDER develops the optimum solution for each dredger. The parts of the gearboxes  are carefully chosen from the great variety of well-established and highly standardized components of the FLENDER range.
