The Sea Technology Floating Terminal, the SFTF 

The Sea Technology Floating Terminal (STFT) is an innovative floating port solution designed for large-scale container transshipment, with an annual handling capacity of 5–6 million TEU. The concept has recently been awarded Approval in Principle (AiP), confirming its technical feasibility confirming its technical feasibility under the DNV rules.

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.

The floating terminal model also holds great potential for other industries, such as floating nuclear plants and the cruise sector, offering scalable infrastructure solutions across diverse maritime applications.

Research 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.

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.

  • Automation: Fully automated cargo handling and registration systems for high throughput and safety during 24/7 operations.

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.

 

Floating Nuclear Power Plant(FNPP)

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.
