Lloyd's Register has granted an Approval in Principle for a hybrid nuclear-ready power concept, a joint development with Australian ship design firm Seatransport. This innovative concept integrates Micro Modular Reactors (MMRs) with traditional diesel-electric systems, designed for two amphibious stern landing vessel models measuring 73 and 90 meters. The approval comes after years of technical collaboration, during which the organizations proved that licensable MMRs can be safely combined with existing diesel-electric propulsion. This fusion aims to create long-range vessels with significantly reduced fuel reliance and emissions. Sea trials on a recently launched 73-meter stern landing vessel, operating conventionally, validated the design assumptions for MMR integration, providing a solid technical basis for the hybrid configuration. Seatransport's stern landing vessel platform boasts over 25 years of operational experience. Incorporating hybrid nuclear capability is expected to provide virtually unlimited operational range, enhanced mission endurance, and dependable performance in challenging conditions, including remote and unprepared coastal landing sites. This approach also promises reduced dependence on conventional fuels and lower emissions throughout the vessel's operational life. The MMR units being considered range from 1.2 MW to 2.6 MW and are currently undergoing technical and regulatory assessments.
