IS THE FUTURE FLOATING?
If onshore wind was the first generation in wind-farm technology, which informed offshore fixed-bottom wind farms, floating wind farms are effectively the third generation.
Floating offshore wind will be able to build on the developments made in seabed fixed offshore wind to reach scale even faster – much as today’s offshore wind industry was built on achievements onshore.
As of October 2022, only around 50 floating offshore wind turbines have been commissioned, says Davies. But global stock is expected to exceed 5 GW by 2030 and 25 GW by 2035.
While fixed-bottom wind farms cost less to install, the real potential for power generation is floating on the horizon. In 2019 the potential for offshore wind power globally could be 18 times the current global power demand - with the majority where waters are deeper than 60m and better suited to floating turbines.

Anchoring System
Design and Development
The anchoring system refers to the anchor chain equipment that fastens the floating structure to the seabed to avoid displacement and dumping due to the influence of wind, waves and currents.
- Tension-leg mooring system
- Catenary loose mooring system
- Ballasted catenary mooring system
We can custom design and develop anchoring systems for projects, and design standard specifications are based on loading analysis of specific site-specific external conditions, including wind, waves and currents.

Limiter Technology
The offshore wind power bending limiter is mainly used in the construction stage of submarine cables or in special working conditions to effectively prevent excessive bending of submarine cables.
With the increasing development of offshore wind power, polyurethane submarine cable bend limiters are used for the protection of flexible hoses such as submarine cables. Mainly in recent years, the submarine cable damage caused by the transitional bending of the submarine cable has caused huge economic losses to offshore wind power and so on.
OUR BENDING LIMITER TECHNOLOGY
- Polyurethane material is more corrosion resistant.
- Modular occlusal structure is adopted, the length can be increased or decreased according to the application environment, and the processing and customization performance is stronger.
- The bending limiter can withstand 8 Tons of lateral pressure, and the pressure resistance is better.
- Accept customized design, more convenient installation.
Most of the bending protection systems in China are made of ductile iron. Because of the material, the ductile iron submarine cable protection pipe has obvious defects such as heavy weight, easy corrosion and inconvenient installation.

Buoyancy Modules Technology
Floating Offshore Wind Cable Buoyancy Modules provides distributed buoyancy for cables used in floating wind applications. This buoyancy can reduce top tension loads, as well as support compliance in the cable during movement of the floating platform.
These modules are designed with an integral elastomeric clamping system that allows the modules to remain securely in place, resisting both axial and torsional loads. Compression of the clamp is maintained by either standard hardware or by strapping systems.
WHAT WE DO
- Modules custom-designed for each application.
- Floating modules deployment strategy.
- Design and production of floating modules.
