- Lloyd’s Register, Seatransport, and Deployable Energy held a HAZID workshop to assess the feasibility and safety of modular micro reactor (MMR) use in maritime vessels.
- The MMR-powered vessel will operate for 8–10 years without refuelling and provide sustainable power to both ship and shore.
- Experts identified key design, regulatory, and risk management strategies needed for nuclear-powered maritime operations to move forward.
Lloyd’s Register (LR) has successfully conducted a Hazard Identification (HAZID) workshop to assess risks and operational parameters associated with deploying modular micro reactor (MMR) nuclear technology in maritime environments. This initiative could revolutionize sustainable propulsion and energy generation for remote or off-grid locations via sea-based platforms.
Collaborative Expertise on the Gold Coast
Held at Seatransport’s headquarters on Australia’s Gold Coast, the international workshop brought together a multidisciplinary team from LR, Queensland-based Seatransport, and Houston’s Deployable Energy.
The session concentrated on:
- Risk management
- Safety systems
- Regulatory compliance
- Vessel design implications
The goal: define clear certification pathways and establish compliance benchmarks to support nuclear licensing and operational readiness.
Towards Nuclear-Powered, Self-Sustaining Vessels
The workshop is a part of a wider collaboration between LR, Seatransport, and Deployable Energy to develop maritime nuclear power solutions for propulsion and emergency applications. Using MMRs, the proposed 73-metre stern landing vessel will operate independently for 8–10 years without refuelling and provide power to shore grids when docked or in emergency zones.
Expert Perspectives
“MMR technology not only reduces our dependence on traditional fossil fuels but also provides a reliable, long-term energy source that can support both operational and emergency needs in remote and underserved regions.”
— Matt Palmer, Global Nuclear and Naval Submarines Segment Director, Lloyd’s Register
“By bringing together leading experts in the field, we have not only identified the key challenges but also outlined strategic solutions to overcome them. These will now be incorporated into the vessel design. This collaborative effort has significantly strengthened our partnership and set a clear path for future advancements using MMR technology for sustainable maritime energy solutions.”
— Remko Hottentot, Commercial Manager – Australasia, Lloyd’s Register
“In my many years advocating nuclear propulsion, I believe now for commercial ships it is within reach and will be commonplace by 2030. My thanks for all visionaries working in this space.”
— Dr Stuart Ballantyne, Chairman, Seatransport
“Deployable Energy is proud to be advancing toward Approval-in-Principle for the hybrid-powered Stern Landing Vessel. Powered by our 1MW Unity Nuclear Battery, this next-generation vessel runs cheaper than conventionally fuelled ships, using safe, standard fuel with no exotic materials. Deployable Energy is delivering clean, scalable energy to transform shipping, resource production, and heavy industry.”
— Bobby Gallagher, CEO & CTO, Deployable Energy
A Pioneering Step Toward Maritime Decarbonisation
This HAZID workshop marks a pivotal milestone in integrating modular nuclear technologies within maritime sectors—bridging safety, innovation, and sustainability. The collaborative framework lays the groundwork for future commercial nuclear-powered vessels and positions the partners at the forefront of energy innovation at sea.
