Deep dredging by Damen at the second highest dam in the world

At 271.5 meters, Georgia’s Enguri Hydropower Dam is the second highest in the world, holding a staggering 1,100,000,000m3 water and 20 turbines producing a total capacity of 1,300MW electricity. According to Damen, this is no ordinary dam, and keeping it free from sediment requires no ordinary dredging equipment.

Situated on a dedicated DCN Diving designed floating structure, a Damen DOP350 submersible dredge pump, plus associated equipment got to work.

In the beginning, the DOP was dredging at depths of -150 meters.

Thanks to its efforts, it’s now working at -170 meters, Damen said.

“It’s not stopping there, however; before it’s done, this DOP dredge pump will be working at depths of -190 meters,” according to Damen.
