2.300 m3 Trailing Suction Hopper Dredger

2.300 m3 Trailing Suction Hopper Dredger

Bottom Dumping, Pump Ashore, and Conveyor Discharge

This versatile French Built, Single Side Arm Trailing Suction Hopper Dredger was designed as a sand and gravel mining vessel capable of efficient production in almost any circumstance. The dredging equipment (supplied by Damen Dredging) features an electric powered submerged dredge pump and jet water assisted California type drag head, providing rich slurry mixtures with relatively coarse sand a gravel. When connected to the onboard centrifugal pump, this dredger is capable of dredging to a depth of 40 m (130-feet). The integrated swell compensation system can compensate for up to a 4 m (13-foot) swell. The Damen Dredging supplied dredging system is state of the art, and fully integrates with dredging instrumentation and automation.

The versatility of this dredger is manifested by her various discharge systems. Not only can she discharge through bottom dumping doors, she can pump ashore, and she is also capable of dry discharge directly onto the shore or dock without any shore infrastructure whatsoever using her onboard cantilevered conveyor.

The vessel can accommodate seven crew members in a fully air conditioned and heated environment with in ample staterooms and separate galley / mess facilities
