BRAND NEW connector for large diameter wind towers
SubseaDesign’s innovative connector design will enable the industry to achieve greater turbine capacity.
L-Flange installation
Motivations for finding new solutions :
- Reduce the need for bolt inspections and replacements.
- Maintenance requirements for bolt groups in L and T flanges are driving the industry away from bolt-based connections for larger windmills.
- 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.
MAIN benefits
- As turbine size increases, current bolted flange designs will reach their technical limits.
- SD Wind Tower Connector offers a number of advantages over traditional bolted 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
- Easy to install:
- Fewer bolts
- Less sensitive versus fabrication tolerances
- Improved HSE compared to T-flanges
- Faster make-up time because of lower number of bolts
