The AMS Factory Acceptance Test (FAT) for the the world’s largest cutter suction dredger JDN 8069, being built for Jan De Nul Group, is taking place at Bakker Sliedrecht this week. 

Bakker Sliedrecht has been involved in this project from the very beginning, brainstorming with Jan De Nul Group about electrical configurations, the company said in its release.

“JDN 8069 is being equipped with very powerful drive systems of 8.500 kW. This makes the new vessel significantly stronger than existing cutter suction dredgers. The powerful drive system crushes rock faster, increasing production,” Bakker said.

Bakker Sliedrecht is engineering, delivering and commissioning four high voltage drive systems for JDN 8069:

  • ​2 inboard pump drive systems of 8500 kW;
  • Submerged pump drive system of 8500 kW;
  • Cutter/propulsion drive system of 8500 kW.

One drive system will power both the cutter and the propulsion since both applications are never used at the same time, thus saving space on board.

All drive systems and switchboards are undergoing FAT at the testing facility of Bakker Sliedrecht. After FAT testing, both the drive systems and the switchboards will be shipped to Jan De Nul Group for installation on board in Uljanik Brodogradiliste shipyard in Pula, Croatia.

The CSD JDN 8069 will be operational in 2017.
