> For both on- and offshore projects, wind turbines dominate the capex split – appropriate turbine prices are thus crucial for attractive return on investment > Offshore investment split varies according to project details, e.g. water depth, distance to shore, grid connection works etc. > Cost of grid connection depends on distance to coast, foundation also depends on depth of water – in contrast to the UK market, the grid operator in Germany is obliged to connect the projects to the electricity grid and to bear capital and finance cost

Talking about offshore wind: What are the major challenges?

1. Demanding weather conditions

2. Key components have to be installed in large numbers

> in deep water (up to 40m)

> great heights (100m+)

3. Unsufficient availability of installation vessels with fitting design

4. Difficult environment and low level of experience for operation and maintenance

Our approach: In the end it comes down to perfect project organisation, logistics and own vessels

Seabreeze Programme:

> Construction of 2 self propelled Jack-Up vessels

> Specially designed for turbines in the 5 to 6 MW class…

> and deepwater environment: possibility to be used in water depth > 45 meters (using leg extensions)
