However, ….

Despite growth of market and turbine sizes, Offshore Wind continues to depend on incentive schemes.

Markets

Customer landscape changed in breathtaking speed from “cash payers” to financed investors.

Customers

Cost of energy

Positive effect of innovation and growth seems to be “eaten up” by increasingly complex projects.

How do we retain market leadership?

How do we ensure a sustainable offshore market

The industry needs to ensure a sustainable offshore market !!!

Our fundamental motivation for the development offuture offshore wind turbines is reduction of LCoE

� Reduction of investment

� WTG investment

� BOP investment

� Reduction of O&M Cost

� Increase of energy output

October 30, 2014



Offshore cost reduction is effective in multiple areas: reaching LCoE below 10 € ct/kWh before 2020

In 2020, wind turbines may look as today – but will be very different …

Onshore

Main Data

�Power rating: 2-4MW

�Rotor: 100-150 m

�Hub heights: 100-200 m

Technologies

�Blades with structural-aerodynamic coupling for passive load reduction

�High-stiffness fibers in blades (carbon, new fiber types)

�Direct drive transmission

�Commoditized design, standard components

�Ancillary services, fault robust with short-term storage

Offshore

Main Data

�Power rating: 6-10MW

�Rotor: 150-210 m

�Hub heights: 80-140 m

Technologies

�Basics same as onshore technologies

�Tailored redundancy concepts for increased robustness

�Two-year service intervals

�Electrical and civil infrastructure at 40% of today‘s cost

�Simplified installation w/o piling

Ideas beyond wind turbine improvement - e.g. today’s Infrastructure design needs Innovation

October 30, 2014



The radical idea to the platform challenge :Simply “No platform!”

Measurement and protection

Turbine switch gear and distribution

Array switch gear

Cable hang-off

Complete AC Booster Turbine

Concept: Platform with 300MVA 220/66kV transformer
