- Allseas to develop Small Modular Reactors (SMRs) for zero-emission power on offshore vessels and industrial clusters.
- Five-year roadmap includes concept design, regulatory approval, and prototype deployment by 2030.
- TRISO-fueled HTGRs offer passive safety, high energy density, and a sustainable path to maritime decarbonization.
Allseas, the renowned offshore engineering specialist, is embarking on a groundbreaking initiative to integrate Small Modular Reactors (SMRs) into its ultra‑large vessels and industrial onshore clusters. By leveraging Generation IV High‑Temperature Gas‑cooled Reactors (HTGRs), the company aims to provide high-density, zero-emission energy for remote, energy-hungry maritime operations and heavy industries.
A Bold New Frontier: Nuclear for Ships and Shore
Drawing on 40+ years of marine engineering excellence, Allseas is designing compact SMRs (\~25 MWe) powered by TRISO fuel, famed for its passive safety and remarkable reliability. These reactors self‑regulate and cool down without external systems, making them well suited for hazardous offshore environments.
Beyond its vessels, Allseas sees onshore industrial clusters as prime candidates for this nuclear innovation—promising consistent power and heat, easing grid strain, and accelerating decarbonization.
Strategic Partnerships & Regulatory Roadmap
Allseas is collaborating closely with the Nuclear Energy Maritime Organization (NEMO), aiming to shape safe standards for maritime nuclear deployments. Simultaneously, they engage regulators like ANVS, IMO, and IAEA to garner pre-licensing support for their SMR rollout.
In parallel, industry partners—including Lloyd’s Register, TNO, NRG-Pallas, TU Delft, and KVNR—are aiding certification and licensing under initiatives like IAEA’s ATLAS, set to establish global nuclear-at-sea standards by the early 2030s.
From Concept to Deployment: A 5‑Year Timeline
- 2025–2026: Finalize concept designs and begin regulatory and safety dialogue
- 2027–2028: Advance to detailed engineering and reactor testing
- 2029–2030: Construct the first reactors at a dedicated facility
- Post-2030: Deploy prototypes on land, followed by integration aboard Allseas vessels
Project Manager Stephanie Heerema emphasizes this aligns with Allseas’ goals—cutting emissions by 30% by 2030 and achieving net-zero operations by 2050.
Responsible Innovation and Sustainability
Allseas is committed to a full-life-cycle approach. They’re researching reuse of reactor materials, such as graphite, and TRISO fuel reprocessing to reduce nuclear waste. Safety remains a core value, with passive systems, containment ceramics, and a proactive stance on transparent environmental stewardship.
Decarbonizing Maritime and Industrial Sectors
- Unmatched energy density: Ideal for long-duration offshore missions where renewables aren’t viable
- Stable zero-carbon energy: Reliable power unaffected by weather or volatile fuel markets
- Industry-wide impact: Offshore and industrial segments can bypass grid congestion and fossil dependency
As ships and heavy industry seek deep decarbonization, nuclear-powered solutions are emerging as game‑changers. Allseas is positioning itself at the forefront of this green shift, potentially transforming how offshore vessels and remote industrial hubs generate power.
