A fully automated, floating transshipment hub
The Sea Tech Floating Terminal is a large-scale, modular offshore terminal engineered for efficient transshipment of containers — deployable in strategically protected waters near major maritime routes.
- No seabed dredging required
- 60-year design life,
- DNV validated
Supports vessels up to 30,000 TEU - Compatible with hydrogen, ammonia, methanol
- Modular and relocatable
A floating port like the STFT offers a transformative solution to the capacity and energy challenges faced by many regions, including the Philippines, Indonesia, and the Arctic North, where traditional infrastructure struggles to keep pace with rising trade demands. Conventional ports in these areas are often limited by shallow waters, making large-scale development slow, costly, and environmentally damaging.
The STFT adds significant capacity by offering a scalable, modular terminal that can be deployed rapidly in regions where land-based ports would be financially or logistically prohibitive. With its design, the STFT can ease pressure on existing infrastructure, facilitate trade growth, and reduce environmental strain.
Beyond logistics, the STFT also serves as a sustainable energy hub. With integrated freshwater production and waste-to-energy systems, it can generate vital resources for its own operations and the vessels it serves. In regions with underdeveloped or unreliable energy grids, this capability provides clean, renewable power while enabling feeder vessels powered by batteries or alternative fuels, further reducing dependence on fossil energy sources.
This multifunctional role opens new opportunities for regional industries—from fishing to waste management—by creating a shared hub that supports both maritime and onshore activities.
In regions where port congestion and inadequate infrastructure slow economic growth, the STFT provides an agile, efficient, and environmentally responsible alternative. Its ability to be deployed without extensive dredging, land reclamation, or lengthy construction timelines allows developing economies to expand capacity quickly and connect more effectively to global trade networks.
Reserach Collaboration with RISE
Sea Technology, in partnership with the Research Institutes of Sweden (RISE), has conducted applied research into the climate and logistics potential of floating container terminals.
The joint study, “The Transformative Role of Floating Container Terminals in Sustainable Supply Chains and Climate Resilience”, highlights how the STFT model can:
-
Reduce port-related CO₂ emissions by decentralizing cargo handling and minimizing vessel idle times.
-
Improve regional logistics efficiency through optimized feeder operations and reduced congestion.
-
Enhance climate resilience by enabling flexible, relocatable port capacity in vulnerable coastal regions.
-
Support the Blue Economy, creating synergies between maritime infrastructure, renewable energy, and sustainable coastal development.
This collaboration validates the strategic role of floating terminals in achieving both environmental and economic sustainability — reinforcing Sea Technology’s commitment to smarter, cleaner, and more resilient oceans.
AiP by DNV
Sea Technology has reached an important milestone in the development of its Sea Technology Floating Terminal (STFT), receiving an Approval in Principle (AiP) from DNV, one of the world’s leading classification societies for maritime and offshore industries.
This recognition marks a significant step forward in the validation of our innovative floating port terminal concept, designed to redefine how logistics, energy, and marine production can operate in offshore environments.
The Approval in Principle confirms that the STFT concept is technically feasible and can serve as a foundation for detailed engineering and future construction. DNV’s assessment was conducted under the class notation OI Floating Infrastructure Installation, with reference to relevant offshore structural design standards
While the AiP focuses primarily on the hull structure and general arrangement, it establishes that the submitted design documents meet the necessary principles and requirements for further development toward full classification and construction.
“This AiP marks an important validation from one of the most respected authorities in our industry,” says Therese Lundquist, CEO of Sea Technology International. “It not only strengthens confidence in the STFT’s technical integrity but also supports our mission to bring sustainable, floating port infrastructure to regions where it can have the most impact — from the Baltic Sea to Southeast Asia.”
Dynamic Floating Terminal - Configurable for RoRo and Container Operations
The Sea Technology Floating Terminal (STFT) is a large-scale, modular offshore terminal engineered for efficient transshipment of containers, vehicles, and heavy cargo units. The platform’s structural concept allows for custom configuration to suit various operational requirements, including RoRo, container, and hybrid functions.
RoRo Integration
The RoRo version of the STFT incorporates dedicated ramp systems and multi-deck vehicle garages to support pure car carriers (PCCs) and RoRo vessels up to 240 × 40 m.
Garage capacity: Approximately 80,000 cars in a superstructure above the terminal deck, with space for an additional 100,000 vehicles on deck.
Ramp system: Wide, double-lane sloped ramps (1:6 gradient) provide efficient vehicle access between the terminal and garage levels.
Operational facilities: Heated, ventilated, and illuminated car decks equipped with charging stations, inspection areas, and documentation handling zones for vehicle processing.
Flexible Modular Design
The STFT is dynamic in layout and can be scaled or extended depending on mission and location.
-
Available configurations include three or four hull modules welded together, forming terminal lengths between 600 m and 700 m and a beam of 372 m.
-
Adaptable for both container stacking (up to 60,000 TEU, 6 high) and RoRo cargo, using Megamax STS cranes with outreach of up to 80 m and backreach of 42 m.
-
The terminal integrates Trelleborg AutoMoor systems for safe, line-free mooring in offshore conditions.
A High-Capacity Floating Port Solution
With a total operational load capacity exceeding 1 million tons, including 1.5 million tons of ballast water, the STFT provides a stable, self-sustained offshore logistics platform. It is designed for deployment in deep water (up to 1,000 m) and can operate independently or as part of a network of floating terminals.
