Oshima Shipbuilding’s multi-fuel-ready Ultramax bulk carrier
Lloyd’s Register (LR) has granted Approval in Principle (AiP) to Oshima Shipbuilding Co., Ltd. for its innovative multi-fuel-ready Ultramax bulk carrier design. This approval, presented on January 23, 2026, at Oshima’s headquarters in Japan, marks a significant step towards enabling the bulk carrier sector to transition to lower and zero-carbon operations. The design accommodates various future fuel options, including ammonia, methanol, and LNG, while also incorporating onboard carbon capture and storage (OCCS) capabilities.
Innovative Design Meets Industry Needs
The newly approved 64,000 deadweight tonnage (dwt) bulk carrier concept is designed to provide flexibility for shipowners, allowing them to postpone final fuel decisions without compromising asset value or operational relevance throughout the vessel’s lifespan. This multi-fuel approach is particularly crucial as the maritime industry faces uncertainty regarding future fuel pathways and regulatory frameworks.
Lloyd’s Register conducted a thorough technical review of the design under its ShipRight Risk Based Certification framework. This assessment focused on the safety, feasibility, and integration of the proposed fuel and carbon capture systems, ensuring that the concept is ready to advance towards detailed design and potential construction. Sung-Gu Park, North East Asia President at Lloyd’s Register, emphasized the importance of this flexibility, stating that it equips shipowners with a resilient solution as they navigate their decarbonization strategies.
Oshima Shipbuilding Unveils Versatile Multi-Fuel Carrier Design
Dr. Junichi Man, Managing Director of Oshima Shipbuilding, expressed pride in receiving this approval, highlighting the growing need for adaptability in the face of diversifying fuel options and evolving global regulations. He noted that the collaboration between Oshima’s engineering team and LR’s experts was instrumental in achieving this milestone, enhancing the design through rigorous risk-based assessments. This AiP not only strengthens the partnership between LR and Oshima Shipbuilding but also underscores the critical role of early-stage assurance in promoting the adoption of next-generation maritime technologies.
