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 24,000 TEU today. 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

Moored in deep water offshore, the STFT lets ULCVs berth without channel or harbour dredging, sparing both capex and coastal ecosystems.

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 shipyard and towed to its final location, the STFT® can be fully operational within just six months of construction completion, compared to up to ten years for a conventional land-based terminal.

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. Holds DNV Approval in Principle and has a 60-year design life. Relocatable when port economics shift.

5 to 6 million TEU per year, on a 600 by 400 m platform

Serves today’s 24,000 TEU ULCVs and is designed for the coming 30,000 TEU generation. Trelleborg & Cavotec's AutoMoor line-free mooring and Megamax STS cranes with 80 m outreach handle the load. Major-hub throughput 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 maintenance dredging program and a minimal seabed footprint.

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)

Issued October 2025 under DNV’s Floating Infrastructure Installation class notation, confirming the technical feasibility of the STFT’s core concept. 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.
