2. Modules of Project Certification Design Basis (Site Assessment)

• Site Assessment• Environmental Conditions

wind, wave, ice data, …• Soil Investigation

soil investigation programme, soil data, soil model, p-y curves• Further Items

• Load Case Definitions combination wind - waves

• Determination of Rules for materials, corrosion protection• Assumptions for WT: masses, eigenfrequencies, …• Concept for Transport, Erection and Inspection• Specification of specific Analysis Methods

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 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.

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

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.

decrease of staff cost savings for the client

2. Modules of the Project Certification


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

• 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

http://www.bsh.de/



• confirmation of fulfilling technical requirements will leads to (international) acceptance
