Looking for a Wind tower Flange ? Discover our groundbreaking connector type for large diameter wind towers
SubseaDesign’s innovative connector design is an enabler for further growth in turbine capacity.
features and benefits
- Current wind tower flanges use a bolted flange design that will reach its technical limit as the turbine size increases.
- SD wind tower connector has a number of advantages compared to traditionally bolted wind tower flanges:
- Substantially higher structural capacity
- Close to unlimited scaling capability
- Superior fatigue capabilities
- 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
- Less sensitive versus fabrication tolerances
- Improved HSE compared to T-flanges
- Comparatively faster make-up time because of lower number of bolts compared to traditional wind tower flange

Motivations for finding new solutions :
- Maintenance requirement for Wind Tower Flanges (bolt groups in L and T flanges) are a major driver for moving away from bolts as the main structural element in the connection of larger windmills.
- Reduce the need for bolt inspections and replacements.
- Larger windmills may require 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.
