Com4Offshore – Interactive Communication and Monitoring
System for Offshore Wind Energy
ESA ARTES Applications Workshop 2015, Geneva
The setting
Planned capacity of Offshore Wind in Europe and Germany
 Europe moves towards a fully
decarbonized power system by 2050.
 EU targets renewable energies to
provide 20% of Europe's energy supply
by 2020 (“20-20-20 targets”).
 Offshore Wind Power is a key pillar of
electricity source in the future.
 Offshore Wind Energy is able to
provide base load power.
 The Offshore Wind Energy deployment
has just begun.
„Germanys wind mills produced 9 Billion kWh per
month in December 2014, more than all German
nuclear power plants together in one month in
2013 (8 Billion kWh).“

Offshore Wind Market
Dimensions of the market
 Investment costs per wind park (80 x 5 MW turbines):
ca. 1.5 billion €
 Construction time: ca. 2 years per wind park
 Daily charter rates:
up to 100,000 – 250,000 € per vessel
 Over 20 vessels of various types can be located
simultaneously within the wind park
 Several hundred employees are working on different
vessels, installation barges or fixed offshore platforms
User Overview
