Looking for a Wind turbine Flange ? Discover our groundbreaking connector type for large diameter wind towers
SubseaDesign’s innovative connector design will enable further growth in the turbine capacity of offshore wind farms.
features and benefits
- Current wind turbine flanges make use of bolted flanges. This design will reach its technical limit as turbine size increases.
- SD Wind Tower Connector has several advantages over current bolted flange designs:
- A substantially higher structural capacity than other designs
- Superior fatigue capabilities
- Close to unlimited scaling capability
- The bending moment does not run through the bolt (it runs through clamp segments), so bolt tension remains constant.
- Improved fatigue life
- Reduced maintenance cost
- Installation friendly:
- Fewer bolts
- Improved HSE compared to T-flanges
- Less sensitive versus fabrication tolerances
- The make-up time for a wind turbine flange is faster than traditional flanges because it has fewer bolts.

Motivations for finding new solutions :
- Reduce the need for bolt inspections and replacements.
- Maintenance requirements for wind turbine flanges (bolt groups in L and T flanges) are one of several factors driving the move away from bolts as the main structural element in larger windmill connections.
- Large windmills may have to use T-flange connections with outside bolts:
- Exposed to corrosion
- HSE challenges under mounting and maintenance
- Enable increase of turbine capacity beyond the limitations set by current solutions.
