Driven by today’s hands-on experience to cut offshore costs significantly, nezzy² is a fully integrated system approach based on an inexpensive floating main body made of pre-casted and post-tensioned concrete elements. Key elements are:
- Two Counter rotating rotors ➔ Balanced rolling moment
- Downwind, self-aligning system ➔ No yaw system, reduced RNA weigh
- Turbine interface flange for drive train integration ➔ different turbines applicable
- Tower with aerodynamic shaped structure ➔ Low drag, low tower-blade interference and support of self-aligning
- Pre-tensioned synthetic guy ropes for load transfer ➔ Reduced tower bending loads and weight
- Foundation built from pre-casted, post tensioned concrete segments ➔ Cost-effective and time-saving series
- Segmented ellipsoid GFRP floater ➔ Optimized buoyancy and low drag force
- Turret Mooring System ➔ Easy disconnection of mooring
- Synthetic mooring elements ➔ Mitigation of loads and costs
