2. Modules of Project Certification Site Specific Design Assessment
• Load Assessment• Assessment of the support structure
• ULS (ultra limit state)• FLS (fatigue limit state)• investigation of details e.g. for Grouting connection, 2nd-steel
• Assessment of the turbine • Marinisation• Are site specific loads higher than those in the Type Certificate? in case: reserve-calculations

2. Modules of Project Certification Transport- and Installation Surveillance
Transport and Installation Inspection (TII):
Securing quality during transport and installation in terms of the certification and on behalf of the client
Marine Warranty Survey (MWS):
is required by the insurer and comprises:
• Assessment of the selected ships/barges and equipment
• Marine operations / enviromental conditions Keyword: in the sense of `loss of cargo`

GL suggests to merge the MWS scope together with the TII scope.
The combined scope can be performed by one GL inspector on site.

2. Modules of Project Certification Periodic Monitoring
To keep the Project Certificate valid a periodic monitoring is required.
• Inspection of the entire wind turbine by technical experts
• Offshore: 25% of the WTGs per year to fulfill BSH requirements. After 4 year all WTGs
shall have been inspected
• Transformerstation:annual inspection

3. The benefit of Certification
European Offshore Wind Conference September 2009 No. 18
3. The benefit of Certification
• Fulfilling requirements of the authorities e.g. BSH in Germany: ``Standard Design of Offshore Wind Turbines````Standard soil Investigations for Offshore Wind Farms``
(see also www.bsh.de for download)
• Risk minimisation acc. to: „four-eyes principle“
• Higher qualitiy during manufacturing by independent inspections
• Trust worthiness for insurers, financiers and banks
European Offshore Wind Conference September 2009 No. 19
3. The benefit of Certification
• confirmation of fulfilling technical requirements will leads to (international) acceptance
