A New Modular Heavy-Duty Floating Bridge System Backed by Hann-Ocean's Proprietary Technology and Brought to Market Through Jiangsu Tairun

Today marks the official launch of a modular heavy-duty floating bridge system powered by Hann-Ocean Technology’s proprietary technology platform and manufactured and integrated by Jiangsu Tairun.

Originally developed as a key system for major engineering applications, the platform has undergone four years of focused research, testing, and technical refinement. Its unveiling represents more than the release of a new floating bridge solution — it showcases the successful integration of internationally developed core technology with advanced Chinese manufacturing and engineering execution.

A Strong Foundation of Brand and Technology

RigiFloat: A Modular Pontoon System Built to International Standards

Hann-Ocean’s globally registered trademark RigiFloat represents a modular pontoon system developed on the foundation of internationally recognized ship design principles and engineering standards.

Supported by a mature proprietary technology platform and aligned with the technical frameworks and verification standards of internationally respected classification societies such as DNV, Lloyd’s Register (LR), and the American Bureau of Shipping (ABS), RigiFloat reflects a world-class approach in production management, manufacturing precision, quality control, and after-sales support.

As Hann-Ocean’s OEM manufacturing partner, Jiangsu Tairun is responsible for product fabrication, system integration, and engineering implementation. Together, the two parties bring to market a complete modular floating bridge solution supported by Hann-Ocean’s established commercial channels and service network.

From brand positioning and core connection technology to production, integration, delivery, and support, this collaboration demonstrates the full value of a highly coordinated international engineering partnership.

Engineered for Fast Deployment

From Factory Floor to Waterborne Operation

From the outset, the design brief was clear:

Heavy-duty capability. Modular architecture. Easy transport. Rapid deployment.

To meet these requirements, the project team carried out extensive engineering development and validation. Inside the production facility, heavy-duty modules, standardized structural units, and precision-machined steel connectors come together to form the backbone of the system.

These connectors are not simply joining elements — they are central to the bridge’s speed of assembly, structural stability, and operational safety.

Each component undergoes precision machining, controlled assembly, and rigorous testing. Every interface is manufactured to millimeter-level tolerances, ensuring fast connection, secure locking, and reliable load transfer across a wide range of water conditions.

This is where engineering discipline meets execution: a modular bridge system shaped by precision, performance, and practical deployment demands.

Rapid Bridge Formation on Water

A Heavy-Duty Floating Bridge Taking Shape in Under Four Hours

One of the system’s most remarkable strengths is its deployment speed.

On open water, under the precise operation of heavy-lift cranes, core modules are sequentially positioned, connected, and secured. In less than four hours, a heavy-duty floating bridge spanning the river can already be formed.

This speed is made possible by the combined advantages of modular design and Hann-Ocean’s mature connection technology.

The system is highly adaptable. Modules can be added or removed according to river width, operating conditions, and project requirements, allowing configurations that range from tens of meters to nearly one kilometer in span.

Just as importantly, the system does not depend on permanent bridge piers. Instead, it relies on its own buoyancy and anchoring system to create a fast, flexible crossing solution.

The result is simple and powerful:

Deploy on arrival.
Assemble quickly.
Open access fast.

For emergency response, disaster relief, temporary docking facilities, cross-water access, and complex engineering operations, this capability delivers immediate real-world value.

Built for Heavy Loads

Designed to Carry Serious Equipment with Confidence

When tracked excavators move across the deck, the bridge remains stable, showing only minimal settlement of a few centimeters under load.

That level of performance is the result of integrated engineering across the entire system.

Each core module offers up to 50 tons of buoyancy reserve. The deck is designed with anti-slip protection, anchoring points are reinforced, and the structure as a whole is engineered for coordinated load distribution and stability control.

This allows the bridge to support the safe passage of armored vehicles, heavy trucks, and large construction equipment with confidence.

This is not simply a floating platform assembled from modular units.
It is a purpose-built heavy-load bridging system engineered for demanding operating environments.

Precision-built.
Heavy-duty by design.
Reliable where it matters most.

More Than a Product Launch

A Demonstration of Technical Collaboration and Engineering Capability

The launch of this modular heavy-duty floating bridge system is not the story of a single product or a single company. It is the result of close collaboration between Hann-Ocean’s proprietary core technology and Jiangsu Tairun’s manufacturing and systems integration expertise.

Hann-Ocean provides the technology platform, brand support, and market channel foundation. Jiangsu Tairun delivers the manufacturing, integration, and engineering execution needed to bring the system into real operating scenarios.

Together, the two companies have transformed a technical concept into a deployable solution — and an engineering platform into a commercially viable, application-ready system.

This is a powerful example of how advanced proprietary technology, precision manufacturing, and practical marine engineering can come together to create meaningful capability for complex water environments.

Looking Ahead

After four years of development, the system is now ready for the market.

Backed by the RigiFloat modular pontoon system concept, enabled by Hann-Ocean’s proprietary technology, and delivered through Jiangsu Tairun’s manufacturing and engineering integration, this modular heavy-duty floating bridge system is positioned to support a wide range of applications, including emergency rescue, engineering construction, temporary docks, and cross-water access infrastructure.

Its launch marks an important step forward in improving rapid deployment and mobility support in complex water conditions — and opens the door to more efficient, more reliable floating infrastructure solutions for the future.
