Damen DOP250 Dredge Pump for Waterway Constructions

Waterway Constructions, a Sydney based maritime contractor, has taken delivery of a Damen DOP250 submersible dredge pump.

The DOP250 is a wear-resistant, submersible dredge pump, capable of moving 1,250 cubic meters of material per hour through a 250mm pipe.

In 2014, Damen delivered a Crane Barge 3216 to Waterway Constructions, and this latest order is a welcome continuation of an established relationship.

The first assignment for the DOP250 pump is at a bulk liquids terminal at Mayfield, Newcastle, owned by Stolthaven Australia.

Stolthaven is developing a new wharf in this area to allow for the berthing and mooring of vessels up to 100,000 tonnes DWT.

The wharf will provide a 270-meter long by 20-meter wide berth protruding from the existing sheet pile wall, and the project features a steel combi-pile wall including side walls and submerged wing walls.

The DOP250 is playing a central role in the dredging of all the material from within the dredging envelope and the dredging and shaping of the revetment slopes.

Chris Hickey, Project Manager at Waterway Constructions Pty Ltd, said: “The DOP250 dredge pump has proven to be the perfect solution to the project’s dredge requirements, with the performance of the cutter unit particularly exceeding all expectations.”

“The Damen dredge pump was easily fitted to the excavator and paired with Waterway’s hydraulic power pack has pumped the high concentration dredged material through the discharge pipe to the adjacent reclamation area with extremely high output and fuel efficiency.”

Work on the project began in April last year and is scheduled for completion in August 2017.
