EST-Floattech chosen to power hybrid crane vessel “Stormvogel”

Dutch family owned company ”Oeverwerken" opts for a green battery solution

Battery Capacity336 kWh
MarketTugs and Workboats

One of our latest projects, a hybrid crane vessel named ‘Stormvogel’ went for a succesfull sea trial. Stormvogel is owned by the Dutch family owned company ” Oeverwerken” with the mission to become more green. Compared to a ship with conventional technology, the design of Stormvogel can save 30 percent in fuel.
This is partly thanks to the underwater hull that has been completely redesigned and optimized with the help of computer simulations. As a result, the hull has 30 percent less resistance under water and thus 30 percent fuel savings. This is just one of the many techniques on board to reduce CO2 and emissions.

The entire propulsion is diesel-electric. The crane is also fully electric and will be equipped with a flywheel. This means that when the grab drops, the excess energy is stored and can be used later. This also saves an additional 30 percent in fuel.

Thanks to Oeverwerken B.V., Technisch Installatiebureau Oechies bv, Afresh and PLM CRANES for ordering the Energy Storage Solutions at EST-Floattech.


Optimal safety

The energy storage system (ESS) delivered by EST-Floattech has a raft of integrated safety features. Its unique active balancing
and passive safety system is applied at the module and string level. Heat is dissipated by a simple off-the-shelf aircon unit. The battery racks are a favorable option as they can easily be installed in a modular fashion.
