The SeaTech Floating Nuclear Power Package (FNPP) is an advanced floating energy platform designed to deliver up to 1 Gigawatt of stable electrical power through a dual-generation system combining Small Modular Reactors (SMRs) and dual-fuel generator sets. Built on Sea Technology’s Floating Terminal (STFTe) foundation, the FNPP provides a safe, movable, and long-life energy solution for coastal and island regions, industrial sites, and grid support applications. Its double-hull steel construction, radiation-shielded compartments, and redundant safety systems ensure full operational security in any maritime environment.
Double Power System – Reliable and Redundant
The FNPP is equipped with a Double Power System:
- Step One: Marine diesel oil (MDO) dual-fuel generator sets delivering 100 MWe for start-up, redundancy, and auxiliary systems.
- Step Two: Up to four SMRs, each producing 250 MWe, providing a combined electrical output of 1 Gigawatt (1,000 MWe).
This configuration ensures operational reliability, fuel flexibility, and long-term power continuity under all conditions — from remote industrial operations to coastal grid support.
Engineering and Construction
The FNPP is a fully welded, modular steel structure designed for high stability and extended service life:
- Dimensions: Length 400 m, Beam 200 m, Depth 30 m, Draft 20–25 m.
- Displacement: Approx. 1.6 million tons at operational draft.
- Structural Integrity: Double hull with 6 m safety barriers and cofferdam radiation shields enclosing all reactor zones.
- Anchoring: 24-point anchoring system for secure positioning at water depths between 25–100 meters.
- Lifespan: Minimum operational life of 60 years, designed in compliance with IAEA and classification society standards.
The platform includes large-capacity internal tanks for fuels, ballast water, and fresh water, and supports onboard desalination for high-volume fresh water production.
Safety and Operational Systems
Engineered for extreme safety and resilience, the FNPP is:
- Resistant to earthquakes, tsunamis, and piracy threats.
- Equipped with redundant cooling systems, large spent fuel tanks, and radiation-shielded compartments.
- Features eight 50-ton pillar-mounted cranes and two 20-ton movable cranes for logistics, maintenance, and emergency operations.
- Includes low-positioned piers for tug, guard, and service vessel access, plus a helideck and full crew accommodation superstructure.
Deployment and Applications
The FNPP is designed for deployment and global mobility. It can supply power to coastal grids, island communities, or industrial and military operations in areas without sufficient land-based infrastructure.
