The agreement opens one of the world’s largest commercial shipping fleets to the energy saving device.

The deal was inked after discussions at the Hellenic Institute of Marine Technology, where EcoNavis presented research on the Eco Boss Cap’s performance gains and emissions reductions.

Retrofitted to a vessel’s propeller hub, the Eco Boss Cap improves propulsion efficiency by reducing hub vortex cavitation and optimising water flow. By delivering measurable reductions in fuel consumption and CO₂ emissions of between 3% and 5%, the technology supports the global shipping industry’s transition towards more sustainable operations.

Dr. Batuhan Aktas, Managing Director of EcoNavis Solutions, said: “From our first discussions, it was clear that Franman shares our commitment to environmental sustainability. With its network and deep understanding of the Greek maritime sector, the company is the ideal partner to introduce the Eco Boss Cap to the region’s shipowners. Together, we can help shipowners take meaningful steps toward meeting global environmental standards.”

Founded in 1991, Franman has established itself as one of Greece’s leading Agents of shipbuilding equipment, parts and services, representing more than 200 international manufacturers. As a one-stop-shop partner, the company has equipped over 5,500 ships and today connects more than 700 shipping companies with trusted suppliers and solutions worldwide.

Franman CEO Costis Frangoulis said: “Since our formation, we have supplied our clients with equipment that is proven to deliver results. The Eco Boss Cap offers a straightforward and effective way for shipowners to improve fuel efficiency, cut emissions and save on operational costs. Our partnership with EcoNavis is an opportunity to contribute to a more efficient and sustainable shipping industry while reinforcing Franman’s role as a trusted bridge between innovation and the Greek fleet.”

The agreement also allows for potential expansion into other European markets through Franman’s wider client base.

With a shared commitment to maritime performance and sustainability, the partnership is expected to accelerate the Eco Boss Cap’s deployment across the region, supporting shipowners in meeting decarbonisation goals without compromising operational efficiency.
