Shipping &Military Features
Pipelines, Cables, Mariculture,Sediment, Platforms
Nature Conservation Offshore Wind Farms
MSP at an early stages:(between 2001‐2006)
Defining the actual state of uses
Ascertain priorities of different uses
Set priorities regarding national and international “dependencies”.
Priority list (with regard to UNCLOS)High Safety and efficiency of shipping National and international
contracts [e.g. pipelines, cables] Protection of the marine
environment National/Alliance defence
Others Resources Scientific research Wind farming
Construction of the Alpha Ventus wind farm in the EEZ 60 km off the coast of Germany.
5 MW class turbines:
65 MWh∙day‐1∙windmill‐1
8,000 €∙day‐1∙windmill‐1

sustainable fisheries…)- Set-up artificial reefs
2. Tourism
3. Additional energy resources
4. Offshore Aquaculture
5. Bio-Remediation / Bio-Extraction

Key Issues:
1. Multi-use concepts ease MSP2. Multi-use will have a better acceptance for both
stakeholders and would save costs. 3. Multi-Use concepts will have economic benefits
• Quick procedure• Combined EIA• Shared vessels/personal• training• Additional biomass• etc.
