- The new Ultramax bulker design from SDARI features dual-fuel LNG/hydrogen propulsion with hybrid-electric an d wind-assisted systems.
- RINA granted Approval in Principle after confirming compliance with safety and environmental standards.
- Onboard hydrogen production eliminates storage challenges and supports long-term decarbonization goals.
- Design improves cargo capacity, reduces fuel use, and ensures future-ready flexibility for regulatory compliance.
RINA has granted Approval in Principle (AiP) for a new Ultramax bulk carrier design developed by SDARI in partnership with Almi Marine Management S.A. The announcement was made during Nor-Shipping and marks a key achievement under a Joint Development Project involving RINA, Almi Marine, and SDARI, according to the report published by RINA.
Green Dolphin 64 Platform Supports CII and GFI Compliance Goals
Developed on SDARI’s advanced Green Dolphin 64 platform, the new Ultramax bulker features dual-fuel capabilities using LNG and hydrogen, with a hybrid propulsion system designed for maximum energy efficiency. The vessel features a battery-assisted electric propulsion setup, wind-assisted technologies, and a novel onboard hydrogen-reforming system that eliminates the complexities associated with storing and supplying liquid hydrogen. RINA granted the Approval in Principle after confirming that the vessel meets current safety and environmental standards.
The design marks a significant shift in propulsion technology for merchant vessels. Its streamlined hull allows for greater cargo capacity with lower fuel consumption, while the hybrid-electric system ensures compatibility with future energy solutions. Wind-assisted propulsion adds to overall efficiency.
By producing hydrogen onboard, the vessel sidesteps major logistical hurdles and improves its Carbon Intensity Indicator (CII) performance. This approach supports a gradual LNG-to-hydrogen fuel transition, aligning the ship with GHG Fuel Intensity (GFI) targets and long-term goals for net-zero emissions by 2050.
