PLUG AND PLAY

Independant installation of the mooring lines, the power cables and the FWT

Hawsers counteract wind overturning moment

Lower requirements in hydrostatic stability

Smaller and lighter foundation

66m and 2100tons for 12MW (versus +75m and +2500tons for 6-8MW usually)

Image

Lower mooring loads thanks to the damping provided by the hawsers

Nearly zero offset at the inter-array cables connexion

Smaller footprint thanks to the semi-taut layout (ø 500m versus >1200m with catenary)

Compact mooring system

LONG TERM UPSIZING CAPABILITY

No more vibration issue : the 1st structural eigen frequency is shifted from 0.2Hz to 0.6Hz

Less fatigue : the patented pyramidal structure provides a better stress distribution

BLADE DESIGN CONSTRAINTS SUPPRESSED

Image

The tower clearance constraint disapears

Blades stiffness and weight can be reduced

Cost and fatigue damage due to cyclic inertia loadings are reduced

Blades’ length can be increased

Image

Less aeodynamic disturbances between the legs

Tower shadow effect reduction

Fatigue damage due to flapwise moments is reduced
