Dutch battery company EST-Floattech has launched a range of marine battery systems, known as the Octopus platform, to serve growing and diverse maritime market needs.

The company says that the Octopus Series is set to become the next generation DNV certified battery management system for marine markets. With both High Power and High Energy modules, new, smart and lightweight battery solutions can be installed in virtually any size of vessel. Clients can choose between passive- or active cooling while forced air- and liquid cooling will be made available. Production of the new battery systems is about to start and ‘racks’ become available as of 2022.

The Octopus platform features the Battery Management System (BMS), as the interface between battery and application. Whatever energy storage system the client needs, the BMS always has the same interface, making it user-friendly.

EST-Floattech’s BMS plays a vital part in the safety management of the batteries and offers remote monitoring, diagnostics and service.

EST-Floattech CTO  Diederick Stam said: “We see the market both emerging and growing. Sustainable power solutions are becoming accepted and here and there electrically powered vessels are coming into service. As a result, you see more and more differentiation in the applications needed by shipowners and shipbuilders, not only for direct propulsion, but also for equipment, machinery and peak performance and endurance needs. In addition, new types of applications are being thought of as we speak and we work closely with our clients to get them designed and fully functional.“

The High Energy NMC batteries are designed for long-duration and large-scale battery installations, for systems needing 100kWh up to several MWh and are easy to connect in large series. Maritime applications that have longer charging times, for example medium and large-sized ships sailing electrically up to 8 hours, are typically suited for this system, typical applications being tugs, ferries and other vessels with hybrid or electrical propulsion.

The High Power NMC modules deliver high kW combined with limited energy storage (kWh), which means in practical terms a short charging time. It is thus suitable for ferries that recharge in the short interval between crossings. This solution brings less cost and needs less onboard installation space, and is inherently safe due to multiple safety layers in the mechanical design and the software, meeting strict DNV class requirements.

For applications where space is not an issue, the High Energy LFP battery system comes into play. This type contains no cobalt, cutting cost and conserving scarce resources, making it a more sustainable solution. In addition, these modules form a very stable and safe electrical power solution.

EST Floattech CEO Hans Visser said: “Without a history there is no future. I am extremely proud of the history of our company and the future and further growth that the company is facing. Our new and improved website shows both our history, with the 200+ projects we have delivered in recent years, and gives future perspective with our new state-of-the-art product line. The Octopus Series is another big step towards zero-emission shipping ”
