DENS Maritime Battery
Any Powerhub system, ready for the water.
We integrate DENS Powerhub battery systems for maritime use: on vessels, work boats and port equipment. Electric power on the water, proven with Van Oord.
Built on the Powerhub
The Powerhub, integrated for your vessel.
The Maritime Battery is a DENS Powerhub system adapted for use on board. Our maritime battery packs can be ES-TRIN certified, the European standard for inland shipping. Choose the capacity you need, from 145 to 3,360 kWh, and we integrate it with your vessel or port equipment. Charge it from shore power and keep working, emission-free.
Applications
Electric power on and near the water.
Shore power
Moored vessels run on clean power from the quay instead of onboard generators. This works even where the grid is weak or missing.
- 50 Hz and 60 Hz, as a fixed installation or in swappable containers
- Works with the grid, a generator, or fully standalone
- Less emissions, noise and vibration in port
Used by: ZES, LCG
Product: Powerhub
Electric propulsion
Sail on DENS battery packs that can be ES-TRIN certified, built in as a drop-in powertrain or as swappable containers.
- Fixed: installed like an engine block, for new builds and refits
- Swappable: exchanged or recharged at the quay, with MCS charging
- DENS builds the swappable battery units for ZES
Used by: ZES, Van Oord
Product: Maritime Battery
Terminals and ports
Power cranes and heavy terminal equipment without emissions, and absorb the peaks the grid can’t handle.
- Peak power for cranes, without grid reinforcement
- MCS charging for terminal tractors and reach stackers
- One system powers cranes, equipment and quay operations
Used by: LCG

On-deck energy for work vessels
A Powerhub on deck replaces diesel generators with quiet, emission-free power. It’s ideal near cities and homes.
- For dredging, quay construction and sheet piling
- Powers the vessel and on-deck machines like cranes
- Quick to install and relocate
Used by: Van Oord, Martens en Van Oord, De Vries Werkendam

Frequently asked questions
Can any Powerhub be used on a vessel?
DENS integrates Powerhub systems for maritime use. Tell us about your vessel or equipment and we advise on the right capacity and configuration.
Can DENS batteries be ES-TRIN certified?
Yes, DENS batteries can be certified under ES-TRIN for use on inland vessels. Tell us about your vessel and we will advise on the right configuration and the certification steps.
Which capacities are available?
Powerhub systems range from 145 to 3,360 kWh. On Van Oord’s Christiaan P., two systems of 870 kWh each are installed.
How is the battery charged?
Typically from shore power, for example overnight, as on the Christiaan P.
Is it also suitable for port equipment?
Yes. The Maritime Battery covers vessels as well as equipment in ports.
What service do I get?
24/7 service, remote monitoring of your system, and one planned inspection a year, announced at least two weeks ahead.
