Damen: Unconventional Coastal Protection Project in Israel

Damen recently delivered their DOP dredge pump as a complete turnkey package to Israel, for a unique coastal protection project. 

The DOP doing the job is a DOP200 fitted out with a jet water assisted leveler head. It will mine sand at a max depth of -7m.

The discharge distance to the geotubes varies between 200m and 500m, which the DOP can bridge effortlessly, doing some 800m³/h of mixture per hour,” Damen said.

The submersible dredge pump was installed on a work boat.

A dedicated A-frame has been made to handle the dredge pump and to put is fully overboard when mining sand. On the work boat the hydraulic power pack and jet water pack are located on deck.

Unconventional coastal protection project

Everywhere around the world coasts are under constant attack of the continuous wave action.

To protect the Israeli coastline near Mediterranean cost, a series of breakwaters will be constructed.

These breakwaters will be somewhat unconventional: no concrete structures, but geotubes filled with sand.

A geotube is a textile sleeve which is filled with sand mined locally by the DOP200.

The geotubes, of 660m³ each, will be positioned carefully to reduce the wave forces offshore before they reach the coast line thus preventing erosion.
