8 TÜV Rheinland. Approval for Certification. 2010: Acceptance from the German Authorities (BSH) for Project Certification 2012: DAkkS Accreditation for Component- and Type-Certification Offshore Certification with TÜV Rheinland February

9 TÜV Rheinland. Certification Standards. Standards IEC series GL - Guideline for the Certification of Offshore Wind Turbines DNV Offshore Standard Design of Offshore Wind Turbine Structures BSH Standard Design of Offshore Wind Turbines BSH Standard Ground Investigations for Offshore Wind Farms Offshore Certification with TÜV Rheinland February

10 Project Certification according to IEC The purpose of project certification is to evaluate whether typecertified wind turbines and particular support structure/foundation(s) designs are in conformity with the external conditions, applicable construction and electrical codes and other requirements relevant to a specific site. [ ] The certification body shall evaluate whether the wind conditions, other environmental conditions, electrical network conditions and soil properties at the site conform with those defined in the design documentation for the wind turbine type and foundation(s). The evaluation includes safety and quality. Offshore Certification with TÜV Rheinland February

11 Project Certification according to IEC Type Certificate Assessment of Site Conditions Assessment of Design Basis Assessment of Site Specific Design Manufacturing Surveillance Transport and Installation Surveillance Commissioning Surveillance Certificate of Conformity Certificate of Conformity Certificate of Conformity Certificate of Conformity Certificate of Conformity Certificate of Conformity Final Evaluation Report Project Certificate Operating Phase Periodic Monitoring Offshore Certification with TÜV Rheinland February

12 Project Certification along the course of the project. Separation in phases: Development Design Implementation Final evaluation Verification/assessment of Site conditions wind conditions geotechnical conditions marine conditions weather windows Design basis codes and standards and their hierarchy design parameters and principles support structure concept requirements: manufacuring, transportation, installation, o&m, grid connection Integrated load analysis Verification/assessment of Site-specific wind turbine design requirements Site-specific support structure design design with respect to load analysis design with repect to structural integrety design documentation plans for manufacturing, transportation, maintenance Manufacturing surveillance Turbine and support structure requirements: design documentation, test programs quality system of manufacturer (also sub-suppliers) production process quality control Transportation and installation monitoring of seatransportation Commissioning surveillance Project Certificate of TÜV Rheinland Operation Operation and maintennance surveillance in regular intervals Offshore Certification with TÜV Rheinland February

13 Project Certification Details. Site Assessment. Soil Literature search Bathymetric and geophysical surveys (echo sounding, side scan sonar, seismic surveys) Preliminary geological report At lease one borehole and one cone penetration test (CPT) at each corner of wind farm area and in center, at least 10% of all turbine sites: - soil profiles - soil mechanical parameters - description and assessment of foundation soil Preliminary geotechnical site survey report One boring and cone penetration test at each turbine site Preliminary soil and foundation expertise Geological report Wind Measurements/correlation with longterm data from local meteorological stations - reference wind speed - normal average wind speed - wind speed distribution - wind direction distribution - turbulence intensity - wind shear Modeling wind conditions Wind farm influence Wind conditions Other site conditions Seismicity Salinity Temperature Marine growth Air density Ship traffic Disposed matters Metocean Mean still water level (MWL) Min./Max. still water level Lowest/Highest astronomical tide (LAT, HAT) Water level conditions (short/long term) Site specific measurements Hindcast studies Long term statistical data Wave conditions Correlation between water level data and wind data Site specific measurements Statistical data combined with flow models Currents Ice conditions Offshore Certification with TÜV Rheinland February

14 Examples for Calculations. Leading experts in the fields of static and dynamic calculations, esp. for offshore wind farms: Load analysis Collision analysis FEM calculations Development of methods for the analysis of dynamic pile load tests in close cooperation with BAM (Federal Institute for Materials Research and Testing) SAMCEF software: comprehensive package (all-in-one) for integrated load analysis (total dynamic calculations including soil, wave and wind); integrated calculation methods with broad acceptance Offshore Certification with TÜV Rheinland February

15 TÜV Rheinland Project Certification. Implications. - Confirmation Type-certified wind turbines and foundation designs meet requirements governed by site-specific external conditions and are in conformity with applicable local codes - Assurance for the project the earlier the better As the globally independent Certification Body TÜV Rheinland - looks closely at all aspects of the project - keeps an overview of the progress at any time - supports successful realization with our knowledge - Minimization of technical risks - Assurance for the investors Offshore Certification with TÜV Rheinland February

16 GICON SOF. The GICON SOF ( Floating Offshore Foundation ) Buoyancy elements Vertical bracing Additional diagonal bracing Background Data Applicable from 25 to 350 meters Modular construction, supply chain flexibility Complete assembly at portside Transport of the entire structure to the deployment location Limited impact on sediment Maintenance friendly Entire structure can be towed into port for replacement Offshore Certification with TÜV Rheinland February

17 GICON SOF. Calculation Monopile vs. GICON SOF. operating conditions: - v w = 12 m/s - h s = 1,00 m - T s = 4,5 s - Depth of water 18 m (Baltic 1) Movements of the SOF are less than movements of monopile under operating conditions TLP vs. Monopile Offshore Certification with TÜV Rheinland February

18 GICON SOF- HSVA* Experiments. Scaling after FROUDE Scaling factor λ = 25 Incoming flow angle 0, 22,5 and 45 Only wave loads Fixed (α = 31 ; θ = 90 ) and swimming states Depth of water: 30 m *Hamburgische Schiffbau-Versuchsanstalt GmbH 1:25 scaled modell Offshore Certification with TÜV Rheinland February

19 Document Review Process. Accompanying Design Process. Submission of a document e.g. reports, designs, calculations, analyses, concepts, etc. Revision of document for resubmission Client No Document review by TÜV Rheinland s Experts Conformity/plausibility checks acc. to agreed on rules & standards or Review result: Document status report Approval? Yes Package complete?
