Lloyd’s Register (LR) has approved a hybrid, nuclear-ready power concept developed with the Australian ship design group Seatransport Pty Ltd.
The design enables combining nuclear micro-modular reactors (MMRs) with conventional diesel-electric systems for 73- and 90-meter amphibious stern landing vessels (SLVs). These MMRs range from 1.2 to 2.6 megawatts.
The hybrid concept is the result of several years of collaboration between LR and Seatransport. A 73-meter Seatransport SLV was used as the trial platform.
By incorporating a hybrid, nuclear-ready capability, vessels will gain effectively unlimited operational range and extended endurance while relying less on conventional fuels. This approach also enables reliable operation in demanding environments, such as landing and logistic support on unprepared or remote beaches.
LR is working closely with national authorities on safety, compliance, and operational standards in line with rigorous technical and regulatory assessment. Wider adoption is anticipated in the early 2030s.
