Offshore Wind Industry, last 20y + next 4y

Global Offshore Wind Industry in an important (or critical?) phaseGlobal Offshore Wind Industry in an important (or critical?) phase

1991 – 2011 3,8 GW grid connected-Mainly Denmark and UK-Mainly nearshore, shallow water, 2-3 MW turbines

2012 – 2015 roughly 12 GW in serious development/order- 15 times more than before- thereof:

1/3 in UK and 1/3 in Germany(Final Investment decision in Germany 7 billion €)1/3 in other European countriesand2/3 with financing1/3 so far without financing

Offshore? What kind of offshore?

1. Near to shore, < 20 km, mainly 5 - 15 km from the nearest harbour

2. Shallow water, < 20 m, mainly 5 - 15 m water depth

3. Mainly onshore turbines used with 2 - 3 MW

4. Strong wind regimes

1. Near to shore, < 20 km, mainly 5 - 15 km from the nearest harbour

2. Shallow water, < 20 m, mainly 5 - 15 m water depth

3. Mainly onshore turbines used with 2 - 3 MW

4. Strong wind regimes

(Wind) Data Offshore

-Do we have enough wind data offshore?

-Do we understand the offshore wind farm models? Wakes?

-Do we have enough data about the offshore soil?

For the first time in the world a fully pre-

assembled wind turbine installed offshore

- Total lift of 655 tonnes

100 % reliability for all components

- Main components of course

- But also the small parts, causing offshore high O & M costs

- Big difference to the Onshore Wind Industry

Grid Connection and Storage of Energy

● Talisman Energy & SSE

- 2x 5M

- Installed 2006 & 2007

● Water depth: 45 m

● Distance to shore: 25 km

Offshore Revolution: New wind farm design

Based on Onshore Wind each wind turbine is a full power station on it´s own

vs.

An Offshore Wind power station with “stupid” wind turbines
