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, 2 nd -steel Assessment of the turbine Marinisation Are site specific loads higher than those in the Type Certificate? in case: reserve-calculations

11. European Offshore Wind Conference September 2009 No. 11 2. Modules of Project Certification Manufacturing Surveillance Review of material certificates Inspection of NDT Inspection of manufacturing processes Inspections before delivery Inspection of documentation Inspection of tracebility of the products The general objective is to verify, that the production is done according to the approved drawings, rules and specifications.

12. European Offshore Wind Conference September 2009 No. 12 2. Modules of Project Certification Transport- and Installation Surveillance Monitoring of transport and installation (to and on the site) Monitoring of weather conditions for sea transport (Marine Warranty Survey) Checking the components for damage Inspection of the offshore procedures Inspection of prefabricated subassemblies Witnessing of full commissioning

13. European Offshore Wind Conference September 2009 No. 13 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 `

14. European Offshore Wind Conference September 2009 No. 14 2. Modules of Project Certification Transport- and Installation Surveillance GL suggests to merge the MWS scope together with the TII scope. The combined scope can be performed by one GL inspector on site.  decrease of staff  cost savings for the client
