Lehmann Marine, a supplier of maritime energy storage systems, has received an order to supply six Cube battery systems with a total capacity of 6.6 MWh for Norwegian fish farm supply vessels.
The order was placed by the Norwegian system integrator Elmarin. The six workboats will be built by the Norwegian shipyard Sletta Verft for the fleets of Norway-based companies FSV Group, Cermaq Norway and Frøy[ds_preview].
This order results from the joint vision of Lehmann Marine and Elmarin to provide the shipping industry with state-of-the-art and environmentally friendly energy solutions, especially for the requirements of the fish farming industry. According to a statement on the award of the contract, the sensitive ecosystem of a fish farm is an ideal area of application for emission-free and low-noise vessels with hybrid electric propulsion.
Lehmann Marine relies on lithium iron phosphate
Thanks to their modular design, the Cube battery systems selected for this project can be adapted to the specific requirements of ships with limited space on board. Small and easily accessible battery modules also allow for uncomplicated maintenance. The use of lithium iron phosphate (LFP) technology should not only ensure high performance and reliability, but also improved safety during operation. Compared to conventional nickel-manganese-cobalt (NMC) batteries, LFP batteries are significantly safer. In the event of a thermal runaway, only gas is released and discharged to the outside, according to Lehmann Marine.
Lehmann Marine’s Cobra and Cube battery systems are already being used successfully in numerous projects. These references include the Cobra systems used in the workboat “Chicago”, built by Hitzler Werft for the Hamburg Port Authority, and the world’s first hydrogen-powered dredging vessel “Hydromer”, built by Piriou. Recently, Lehmann Marine was commissioned by the shipyard Ampereship GmbH to supply cube systems for two newly built ferries. In addition, the Bolle shipyard ordered cubes for a series of five traffic safety vessels.
