EST-Floattech has received DNV Type Approval for its Octopus LFP battery system, a milestone in the company’s strategy to support all sorts of electric and hybrid vessels worldwide with different types of solutions that best fit the requirements of the sailing profiles. The approval confirms that the Octopus LFP system meets DNV’s high requirements for safety, reliability and performance, giving shipowners, shipyards and system integrators additional confidence when selecting battery technology for maritime applications.

The Octopus LFP battery system has been developed specifically for high-energy maritime applications. It is particularly suited for vessels with predictable operating profiles, such as ferries, inland shipping vessels and workboats that charge overnight and operate emission-free during the day. The technology is also well suited for hybrid offshore and special-purpose vessels seeking to reduce fuel consumption and emissions while maintaining operational flexibility.

Unlike early maritime battery projects that focused on relatively small installations, the industry is now moving towards multi-megawatt-hour systems capable of powering larger vessels for longer periods. The combination of improved energy density, long service life and enhanced safety characteristics has positioned Octopus LFP as an increasingly attractive option for these applications.

Since entering the maritime battery market, EST-Floattech has delivered more than 350 battery systems based on lithium-ion technology. With the addition of a type-approved LFP solution to its portfolio, the company expects adoption of maritime battery systems to accelerate further as shipowners prepare their fleets for future environmental requirements.

Engineering excellence

“Achieving DNV Type Approval for the Octopus LFP system is the result of an extensive development, testing and validation process carried out by our engineering, quality and operations teams. It shows that the hard work and great collaboration of our team is recognized”

Diederick Stam, Technical Director at EST-Floattech.

“The maritime industry requires battery systems that are not only efficient, but above all predictable, reliable and safe throughout their operational lifetime. With the Octopus LFP platform, we have combined the benefits of LFP chemistry with the proven architecture of our Octopus Series. DNV’s approval confirms that the system meets the high standards required for deployment on board commercial vessels worldwide.”

“The DNV Type Approval process involves a comprehensive assessment of the battery system design, safety architecture, manufacturing processes and verification testing. The approval of EST-Floattech’s Octopus LFP platform demonstrates compliance with the applicable DNV requirements for maritime battery systems and provides shipowners, shipyards and integrators with an independently verified basis for project implementation.”

Supporting the next phase of maritime decarbonisation

According to Joep Gorgels, CEO of EST-Floattech, the approval represents more than a technical achievement. “We see shipowners making long-term investment decisions and they need proven solutions that can support them on changing needs. For more than fifteen years, we have helped customers achieve their goals by supplying our battery technology. Today, we are expanding those possibilities further. Receiving DNV Type Approval for our Octopus LFP system demonstrates that EST-Floattech can now support them with another solution added to the Octopus Platform.”

As the maritime industry continues its transition towards lower-emission operations, EST-Floattech remains focused on delivering safe, reliable and scalable energy storage solutions that help shipowners navigate an increasingly complex regulatory and operational landscape.
