Klaipeda: Removing Contaminated Sediment with Damen DOP350

A Damen submersible dredge pump, type DOP350, was recently delivered to the Finnish contractor Vesirakennus Ojanen Oy for a work in the Port of Klaipeda, Lithuania.

“The DOP pump has been fitted out with a reinforced heavy duty leveler head making it the perfect tool for unloading barges. The head is fitted out with high pressure jet water nozzles, which fluidize the cargo and clean the hopper walls in the process,” Damen said in their announcement.

The DOP350 was mounted onto a Hitachi excavator; both the hydraulic hoses as well as the dredge mixture discharge hose and the jet water hoses are connected to the boom. The diesel-hydraulic power pack was mounted at the back of the excavator – thus forming a compact dredging system.

The job includes emptying a continuous cycle of hopper barges – filled with contaminated sediment. The environmentally sensitive material is being pumped over a total discharge distance of 1 km.

It is expected that this work will be completed by the end of 2018.
