Where are we now ?GROWIAN 1980 – 198890 Mio DM ~ 75 Mio €100m tower – 100m rotor diameter340 ton nacelle3MW capacity
“ We built GROWIAN to proof that it cannot be done!”

Will Ocean Energy develop similar to Wind Energy Industry ?
We are still at an early stage 6MW installed capacity in Europe in 2014!
GROWIAN is still seen as the ignition of wind power in Germany
-Wind & Tidal Energy not a back yard business!!
10 - 50 Mio Euro to get first reasonable full scale prototype in the water

Do we have enough experienced professionals?Young industry – young professionalsEngineers – Researchers - Scientists
Lack of past experience!Oil & Gas sector is experiencing the same – offshore engineers retiring
“ We have very few left, who know how to do it!” (NCE2013)
Industry is competing for the same pool of (young) professionals

We can (need to) do it all!?
Device developers need to fullfill a wide spectrum of roles / duties to get device into the water:FinancingTechnologyO&MEnvironmental aspects

Where do we want to go?
Linking knowledge and transferring skill & expertise across
sectors & disciplines
• Naval architecture• O&G Offshore sector• General power generation• Smart components and composite
materials• Power control – F -One• Economy of scale – wind?• …

Where do we want to go?
Incorporating environmental
issues at an early stage
• Involve licensing agencies• Get expert advice from environmental
scientists• Get public involved• and test your device for these issues

Where do we want to go?
Developing a sectorised industry
• Resource assessment• PTO• Substructure • Foundations• strong supplier backbone!

How will we get there?
Tackling the skill shortage!• Graduate school• Postgraduate training
& education• Dedicated degrees
Provide access to testing facilities
Develop closer links between
research institutions and
industry
Providing a longer term vision for ocean energy sector• Clear funding strategy• Facilitate development
& selection• Political will to develop
this sector
