Floating port capacity for the ULCV era
The world's first DNV approved floating port terminal, developed by Sea Technology and validated through extensive engineering, industry, and research collaboration with organizations including MEYER Floating Solutions and RISE Research Institutes of Sweden.

THE ULCV CHALLENGE
Traditional ports cannot scale to meet the new fleet
Ultra Large Container Vessels carry up to 30,000 TEU. The ports that were designed for the last fleet generation cannot accept them without continuous dredging, multi-decade build programmes, and rising political resistance.
No need for dredging
Continuous dredging burns capex and political capital. Rotterdam-class ports rely on it just to keep depth. Coastal ecosystems take the hit.
3 to 5 years to build
Conventional port expansion outlives the operator who tried to solve the problem. ULCVs in service today need answers in years, not decades.
Reduced emissions & environmental impact
Port carbon intensity per TEU has to come down. Vessel queueing and idle time at congested terminals work against every emissions deadline.
Improved logistics
Complementing existing infrastructure to optimize logistics, reducing congestion and improving supply chain efficiency
Built in a shipyard, towed to location
Built in a controlled shipyard environment, and towed into position, minimizing construction time, cost, and environmental impact.
THE SEA TECH FLOATING TERMINAL
ULCV-grade capacity, delivered in years not decades
The Sea Tech Floating Terminal is a modular, fully automated offshore container transshipment hub. DNV-classed, MEYER-built, designed for a 60-year asset life and relocatable when port economics shift.
5 to 6 million TEU per year, on a 600 by 400 m platform
ULCVs up to 30,000 TEU come alongside. Trelleborg AutoMoor line-free mooring and Megamax STS cranes with 80 m outreach handle the load. Throughput at full Rotterdam-class scale, on a modular footprint that can be relocated.
Operational in under 5 years, with no dredging
MEYER Floating Solutions builds the modules at shipyard scale. Deployment is anchored in up to 1,000 m of water. No coastal disruption, no continuous maintenance dredging programme, no seabed impact.
Clean-fuel power, 100 MW generators
Hydrogen, ammonia, and methanol-capable generator sets power crane and platform operations. Integrated freshwater production and waste-to-energy systems close the loop. RISE-validated carbon-intensity reduction per TEU handled.
Configurable for RoRo and FNPP variants
Same modular base supports a RoRo configuration (~80,000 car garage plus ~100,000 car deck) and the Floating Nuclear Power Plant developed with Blykalla AB. One platform, multiple revenue streams.
DNV Approval in Principle (AiP)
Class notation OI Floating Infrastructure Installation, granted August 2025. The STFT is the first modular floating port at this scale to clear DNV's approval gate, with full MEYER shipyard delivery capability behind it.

A WORD FROM OUR CEO
“Sea Technology has spent more than fifty years engineering the future of how the world moves cargo. The Sea Tech Floating Terminal is the most consequential design we have brought forward. It is the only credible answer to ULCV-era port capacity that does not depend on dredging, and it is ready to build.”
About the STFT, in brief
The most common questions from port operators, shipping lines, and infrastructure planners. Reach out for the long answer.
Yes. The Sea Tech Floating Terminal received DNV Approval in Principle under the OI Floating Infrastructure Installation notation in August 2025. It is the first modular floating port at this scale to clear a major class society's review. Full class certification follows project-by-project as deployment sites are selected.
Five to six million TEU per year on a single 600 by 400 metre platform, with Ultra Large Container Vessels up to 30,000 TEU calling alongside. Trelleborg AutoMoor mooring and Megamax STS cranes with 80 metre outreach handle the load. Capacity is comparable to a Rotterdam-class terminal, in a modular and relocatable footprint.
Under five years from contract to operation. Conventional port expansion projects run fifteen to twenty years. MEYER Floating Solutions builds the modules at shipyard scale, in parallel with site preparation, so on-water and on-land work do not block each other.
No. The platform is anchored in up to one thousand metres of water, so no seabed disturbance, no continuous dredging programme, no coastal landfill. Vessels berth at the floating quay rather than at a fixed shoreline terminal. Local ecosystems are not disrupted. Floating terminals are expected to require less environmental intervention, making regulatory approvals more straightforward than for permanent dredged concrete structures.
Hydrogen, ammonia, and methanol-capable 100 megawatt generator sets power crane and platform operations. Integrated freshwater production and waste-to-energy systems close the loop. RISE Research Institutes of Sweden has validated carbon-intensity reduction per TEU handled relative to conventional fixed terminals.
Yes. The STFT is modular and floating, so it can be repositioned as trade patterns or political economics shift. Asset life is sixty years by design. A platform built for one corridor today can be redeployed to a different harbour or trade lane later, protecting the capital investment.
Sea Technology, a Swedish naval-architecture firm founded in 1972 by Bengt Lundquist and led today by CEO Therese Lundquist as the second generation. The STFT is delivered jointly with MEYER Floating Solutions, with DNV (class), RISE (research), Trafikverket, Blykalla (FNPP variant), and Trelleborg AutoMoor (mooring) as named partners.
