Hann-Ocean Energy Technology and Equipment (Nantong) Co., Ltd.

Hann-Ocean Group is an engineering-driven marine technology company specialising in modular floating infrastructure, offshore engineering, naval architecture and renewable marine technology. Headquartered in Singapore with an R&D and manufacturing base in Jiangsu, China, Hann-Ocean combines engineering expertise with efficient manufacturing and global export capability.

With nearly two decades of engineering experience, Hann-Ocean provides reliable floating solutions for offshore wind, marine construction, ports, industrial operations and coastal infrastructure.

Our flagship product, RigiFloat® Modular Floating Infrastructure System, offers flexible, scalable and heavy-duty floating platforms. Built with standardised modular pontoons and robust connection systems, RigiFloat® Can be configured into modular barges, floating jetties, work platforms, CTV terminals, construction platforms, floating logistics bases and offshore wind support facilities. The modular design enables efficient transportation, rapid installation and future expansion.

Unlike conventional pontoon manufacturers, Hann-Ocean delivers complete engineering solutions. Every project is developed according to operational requirements, site conditions, loading criteria, water depth and environmental factors. Our engineering capability covers naval architecture, offshore structural engineering, hydrodynamics, mechanical engineering and steel structure design to ensure safe,

Reliable and practical floating systems.

Through the development of the Drakoo® Wave Energy Converter, Hann-Ocean has accumulated valuable expertise in wave-structure interaction, floating body dynamics, hydrodynamic performance, fatigue assessment and offshore survivability. This experience is directly applied to the design and optimisation of RigiFloat® Systems operating under waves, wind, tides, currents and vessel berthing loads.

RigiFloat® Is widely used by offshore wind developers, marine contractors, ports, shipyards, dredging companies, engineering consultants and government agencies. Typical applications include floating jetties, modular crane barges, floating work platforms, offshore maintenance bases, floating bridges, logistics platforms and other marine infrastructure.

Quality and engineering verification are central to our projects. We support design through 3D modelling, structural calculations, finite element analysis (FEA), stability assessment and hydrodynamic review. Hann-Ocean also has experience supporting projects involving DNV, ABS, Lloyd's Register and Germanischer Lloyd.

Manufacturing quality is ensured through material inspection, welding control, dimensional inspection, non-destructive examination (NDE), coating inspection, factory acceptance testing and complete project documentation, delivering reliable and traceable floating infrastructure.

The main advantages of RigiFloat® Include modular construction, high structural strength, containerised transportation, rapid assembly, flexible expansion, easy maintenance and reduced project risk. Clients can easily expand their platforms as operational needs grow.

From concept to delivery, Hann-Ocean provides engineering support including layout design, technical consultation, modular configuration, stability review, production coordination, logistics planning and installation support.

Hann-Ocean welcomes enquiries from customers worldwide seeking dependable modular floating systems for offshore, coastal and inland water applications. Whether the project involves a floating jetty, modular barge, work platform or offshore wind facility, Hann-Ocean delivers engineering-LED solutions designed for safety, reliability, flexibility and long-term value.
