EST-Floattech energy storage system installed on SFK ferry Laboe

Maritime energy storage solution provider EST-Floattech has delivered the Octopus Series battery system on the Schlepp- und Fährgesellschaft Kiel (SFK) ferry Laboe.

The ferry, which has been successfully delivered to SFK by Holland Shipyards Group, is the sixth ferry in a series of seven as SFK targets lower CO₂ emissions. The Laboe is equipped with a 560kWh Octopus high energy system, which ensures that energy consumption remains low during sailing as the vessel can switch between generators and the battery system. The vessel can even sail fully emission-free around the city of Kiel, where it transports commuters.

The system was integrated by Holland Ship Electric, which has a longstanding partnership with has EST-Floattech, with many successful collaborations of which the Laboe is the latest.

The integrated energy management system optimizes the use of stored energy, enabling the ferry to operate more efficiently and reduce fuel consumption, leading to lower emissions and operational costs. This system has batteries with high energy density, ensuring optimal performance and long operational life for the Laboe.

Malte Klein, technical superintendent of new-builds, tugs and hybrid/electric ferries at SFK, said, “When the new Octopus high energy system was presented to us for the first time, we were impressed by the overhauled design and HMI features of the system. Simple integration into the ship’s networks and better connectivity to the PMS, moreover the new system comes with a higher safety standard. The performance of the system is more than satisfactory. The system is capable of handling different kind of battery types so it is futureproof.”

Rens Gerritsen, project manager from Holland Shipyards Group, commented, “The new Octopus high energy EST battery system has been successfully integrated into both the hybrid ferry Laboe and the fully battery-powered ferry Dietrichsdorf. The inclusion of state-of-the-art battery racks and covers enhances the overall professional aesthetics of the system. Throughout the construction process, EST-Floattech maintained an open dialog for feedback and suggestions from the shipyard and installer, resulting in a seamless integration of the battery pack into both vessels.”

John van de Sluis, director at Holland Ship Electric, added, “We have done many projects with EST-Floattech, and this was the first with their new Octopus Series energy storage solution, which has improved in many ways and was easily integrated into our power system. We look forward to many more successful collaborations in the future.”

Walter van der Pennen, commercial director at EST-Floattech, said, “We are proud to be part of this transformative project that supports the goals of different parties involved in this project to create a more sustainable maritime industry and help lower the emissions in and around Kiel thanks to the Octopus Series battery system.”
