New Milestone for DE Klop: Construction of an Electric Jet-Suction Dredger for Verhelst Group
Sliedrecht, September 26, 2026 – DE Klop proudly announces the construction of a new ROHR-IDRECO Jet-Suction Dredger, Type ISD 200-22, for Verhelst Group in Belgium.

Delivery of this innovative dredging vessel is scheduled for March 2026. The new electric dredger will replace the current dredger, which has been in operation for more than 40 years.

The dredger will be fully designed and built in the Netherlands by DE Klop in collaboration with Idreco. The project includes:

  • Discharge pipeline: approx. 100 m floating and 450 m land pipeline

  • Basic RTK GPS-Dredge Operation Monitoring System

  • Remote Dredging Monitoring & Control via tablet

  • Partly automated operation with speed and process control

During commissioning, DE Klop and ROHR-IDRECO will support the client to ensure a smooth and successful start-up. The new dredger will be operated by Terra Cosa, part of Verhelst Group.
