2 Agenda Type Certification- Introduction Purpose of Type Certification Governing and technical standards, Design requirements Design codes National Requirements in Europe Requirements in Poland Where certification brings value 2

3 Type Certification Third party conformity evaluation Product Certification Conformity evaluation of Wind Turbines, with respect to Specific standards Other technical requirements Relating to Safety Reliability Performance Testing Interaction with electrical power networks Type Certificate covers a Wind Turbine Type Rotor Nacelle Tower Type of connection between tower and foundation Requirements governing the foundation 3

4 Type Certification Originating in 1980 together with the wind industry as we know it- extensive know how, experience and proven track record Minimization of the risks associated with development and manufacturing Securing investment for operators Certification is considered a must for new designs, quality indicator Linking manufacturers, developers, owners, finance and insurance companies, and regulatory authorities Building trust and confidence in the wind industry 4

5 Type Certification Purpose Design Basis Evaluation Design Evaluation Manufacturing Evaluation Type Testing Type Characteristics Measurements Final Evaluation Type Certificate Foundation Design Evaluation Foundation Manufacturing Evaluation Mandatory Optional Confirm that the wind turbine type is designed, documented and manufactured in conformity with design assumptions, specific standards and other technical requirements Demonstrate that it is possible to install, operate and maintain the turbines in accordance with the design documentation 5

6 Type Certification Type Certification Project Certification Project Certification Design Basis Evaluation Design Evaluation Manufacturing Evaluation Foundation Design Evaluation Foundation Manufacturing Evaluation Type Certificate Wind Turbine / RNA Design Evaluation Site Conditions Assessement Design Basis Evaluation Integrated Load Analysis Support Structure Design Evaluation Other Installations Design Evaluation Design Basis Design Type Testing Wind Turbine / RNA Manuf.

7 IEC series of standards IEC , Design Requirements IEC , Design requirements for small wind turbines IEC , Design requirements for offshore wind turbines IEC , Design requirements for wind turbine gearboxes DNVGL-ST-0376 Rotor Blades for Wind Turbines-> IEC IEC , Acoustic noise measurement techniques IEC , Power performance measurements IEC (TS), Measurement of mechanical loads IEC , Declaration of sound power level and tonality IEC , Measurement of power quality characteristics IEC , Conformity Testing and Certification of Wind Turbines IEC , Full scale structural blade testing IEC , Lightning protection 7

8 IEC Design Requirements Sets up requirements for safety and quality for wind turbine design, manufacturing, installation as well as operation and maintenance manuals Outlines minimum design requirements Is not intended for use as a complete design specification Specification of external conditions, e.g. Wind turbine classes, e.g. I A, II C, III B Wind conditions, normal & extreme wind etc. Other environmental conditions, e.g. temperature Electrical power network conditions Specification of design load cases Requirements for design Control and protection system Mechanical & Electrical system Assembly, installation & erection Commissioning, operation & maintenance 8

9 Design codes possible selections Steel structures Eurocode 3 EN 1993 series Cast components DNV 'Guidelines for Certification of Wind Turbine Power Plants, 1992 GL Guidelines Rotor blades DNVGL-ST-0376 Rotor Blades for Wind Turbines GL Guidelines IEC Bearings ISO 76, Rolling bearings Static load ratings ISO 281, Rolling bearings Dynamic load ratings and rating life Concrete structures Eurocode 2 EN 1992 series Eurocode 7 EN 1997 series Offshore foundations DNV-OS-J101, Design of Offshore Wind Turbine Structures 9

10 Maintenance of Type Certificate Annual Reporting Abnormal and deviant operating experience Major failures or safety issues to be reported to DNV GL immediately Periodic surveillance At least every 2½ year Confirm that the installed wind turbines comply with Type Certificate Recently installed wind turbines or in work shop Scope lower than for Type Certificate 10

11 Local Requirements - examples Germany: BSH, DIBt Denmark: Danish Executive Order India: C-WET 11

12 Type Certification National requirements- Denmark Danish Executive Order BEK 73 'Bekendtgørelse om teknisk certificeringsordning for vindmøller, 31/01/2013 Recognizes mandatory elements IEC National requirements- acoustic noise measurement Must have for all erections in Denmark Issued certificates are required to be send to Danish Energy Agency- Energistyrelsens Godkendelsessekretariat for Vindmøller Constructions permits follow local regulations 12

13 Type Certification National requirements- Germany DIBt- Deutsches Institut für Bautechnik Approval of Tower and Foundation loads Lastgutachten Recognizes IEC Rotor-Nacelle approval Maschinengutachten & Sicherheitsgutachten & Rotorblättergutachten & Elektrotechnischgutachten Constructions permits follow local regulations BSH- Bundesamt fur Seeschifffahrt und Hydrographie Offshore wind farms within EEZ (Exclusive Economic Zone) Maritime and nautical consideration Certain similarities with DNVGL interpretation IEC on Project Certification 13

14 IEC vs. BSH DNV interpretation of IEC BSH process I Design basis Design basis II Design Prel. design 1. Freigabe III Manufacturing Basic design 2. Freigabe IV Installation Site-specific design 3. Freigabe V Commissioning Manufacturing survey Transportation survey In-service Project certificate Installation survey Commissioning survey Project certificate In-service 14

15 Polish Specific Requirements Declaration of conformity for the turbine Provided by the manufacturer, stating with EN, ISO etc.. Construction Permit Operational Permit (incl. Occupancy Permit) Commissioning Wind turbine experts are not engaged Local municipality responsibility for the construction laws UDT responsibility for personnel safety (cranes, elevators, pressure accumulators) 15

16 Added value of Certification Type Certificate: Independent verification of the turbine design, manufacturing process, testing and functionality Completeness of assembly and maintenance documentation- manuals Inspection of an actual turbine for HSE, best construction and assembly practice Check of turbine functionality and safety systems Maintenance of TC Commissioning: Commissioning manual (part of IEC requirements) Commissioning on behalf of governmental bodies (e.g. BSH) Commissioning surveillance 16

17 Added value of Certification Established technical competences Experience with multiple turbine manufacturers, turbine types, sizes and design concepts Technical know-how with quality management system in place Recognition from finance and insurance institutions Security of investment Maintenance and reporting requirement for incidents 2½ year inspection 17
