The Challenge

The cable-operated dredger “Prins 6” is used in hydraulic engineering operations, where the crane accounts for a significant share of energy consumption alongside the main drive.

The vessel required a retrofit solution that could support daily distances, high peak loads during crane operation, limited installation space, and the absence of charging infrastructure along the waterways.

The Solution

TESVOLT OCEAN installed the Kaptein Compass Core battery system, developed for demanding maritime applications and retrofit projects with limited installation space.

Charging is supported by an onshore hydrogen fuel cell generator, enabling overnight charging and a full working day of operation.

The Heart of the System: Kaptein Compass Core

Kaptein Compass Core Battery System

Installed Battery System on Board PRINS 6

  • Total Capacity: ~1.9–2.0 MWh
  • Configuration: 16 Strings
  • Air-Cooled Design
  • Compact Retrofit Footprint
  • Hydrogen-Supported Charging
  • 8–10 Hour Runtime
  • Reduced Maintenance Requirements
  • Designed for Demanding Maritime Applications

The PRINS 6 is powered by TESVOLT OCEAN's Kaptein Compass Core platform, designed specifically for demanding maritime applications. Its compact footprint enables integration into existing vessels while providing sufficient energy capacity for a full working day of commercial dredging operations.

The Results

  • Fully electric operation — zero emissions
  • Full-day operation without intermediate recharging
  • Reliable performance under high peak loads
  • Compact system enables retrofit integration
  • Off-grid solution with hydrogen-based charging

We needed batteries that can charge large amounts of energy in a short time while taking up as little space as possible on board. Crane operations generate high load peaks — so it was essential for us that the battery system is robust and performs reliably even under those conditions.
