Classification society DNV has awarded Viridis Bulk Carriers an Approval in Principle (AiP) for an ammonia fuelled short sea bulk carrier design.
As the industry is looking to bend the carbon curve towards zero, green ammonia is considered one of the most promising options. As production is scaled, the ease of transport and storage and good energy density offers some advantages over other low or zero carbon options – provided the technical and safety challenges are managed. The Viridis Bulk Carriers design, developed by Kongsberg Maritime, is for 5,000 dwt short seas vessels that offer a range (3,000 naut mile) and safety levels equivalent to conventionally fuelled vessels.
André Risholm, Board Member Viridis Bulk Carriers said: “We are delighted with yet another milestone for our ammonia powered short sea bulk vessel. During the AiP process we have had a good constructive process and excellent co-operation with DNV. This is a clear testament to the hard work completed and are important for moving closer to the newbuilding phase. Considering the heightened emission reduction targets set by the EU and IMO, our Viridis vessels will fully adhere to these standards. This will empower charterers to benefit from exceptional greenhouse gas reductions throughout their logistical value chain.”
Tuva Flagstad-Andersen, Regional Manager Region North Europe DNV said: “We are extremely proud to announce the successful grant of the Approval in Principle (AiP) for Viridis Bulk Carriers’ ground-breaking project. DNV introduced the Gas Fuelled Ammonia notation to enable the industry to foster innovation and drive sustainable solutions in line with the most advanced industry standards. This is essential to wider adoption, because building trust is vital as we look to develop the next generation of fuels. With these projects, we demonstrate how by working in collaboration, we can shape the future of shipping and advance towards a decarbonised and sustainable tomorrow.”
For the AiP, DNV reviewed the design of the vessel for compliance with the 2023 revision of the rules for the DNV Gas Fuelled Ammonia class notation as found in Pt.6 CH.2 Sec.14. The 2023 revision will be published in July 2023 and enter into force 1 January 2024.
