Three LDA wind-assisted ro-ro vessels will also feature hybrid propulsion, power management and control technology from BERG

BERG delivers the world's first GreenForge® shafts to the maritime market

Ro-roBERG Propulsion is supplying the maritime industry with propeller shafts produced through the GreenForge® process, developed by Björneborg Steel. This method uses recycled scrap steel, renewable electricity, and fossil-free biogas, reducing CO2 emissions by 95% compared to conventional production, with remaining emissions offset for full climate neutrality.

Three Louis Dreyfus Armateurs (LDA) ro-ro vessels, set to operate from 2026, will use these shafts alongside wind power from rotor sails and hybrid propulsion systems from BERG. The production of six shafts for LDA will cut CO2 by 160 tonnes.

The first shaft is due in March 2025, with five more by June 2025, delivered to BERG’s plant in Hönö, Sweden. The EU’s 'Clean Industrial Deal' is expected to support such processes with incentives and penalties on CO2 emissions, potentially making emission-free methods cost-competitive by 2030. Björneborg Steel plans to fully transition to GreenForge® by 2027, depending on biogas availability, driven by demand from sustainability-focused maritime customers.
