What is Certification?

▪ Certification is the assessment of conformity

– conformity with requirements stated in international ISO, European EN and national

standards, e. g. DIN, NF or BS etc.

▪ Certification is

– In most cases a voluntary procedure to demonstrate that the certified target fulfils the

requirements imposed on it;

– For some industries a legal or contractual requirement.

▪ Certified targets: a product or process, a management system, or

personnel

In the Wind Industry: Product certification

Product certification is related to construction products, electrical equipment and

components or processes such as welding processes

▪ Certification is performed by a Certification Body

6

What is the result of certification?

▪ The certification body issues a

certificate based on the

assessment in which it verifies that

the product, process, management

system, or personnel fulfil the

specified requirements.

▪ Certification is valid for a fixed

period after which a recertification

can be performed.

▪ Certification maintenance is

related to assessment procedures

that must be performed, e.g.

annually, while the certification is

valid.

What is a Certification Body?

▪ Accredited Certification Bodies

– Are impartial third party operators independent of the target of

certification

– Must have the competence specified in international standards and

other prerequisites for their operations attested by accreditation

▪ The certification body assesses whether the system, product or

personnel fulfil the requirements stated in the certification schemes.

How is Certification performed?

▪ Certification methods:

– Document assessment and parallel calculations

– Evaluation of data gathered from practical operations or testing

– Site inspections

•Protection and safety

•Loading

•Structural analysis

•Mechanical & electrical installation

•Examination of drawings

•Examination of components

Test

•Model tests

•Component tests

•Test of the prototype

•Comparison of test results with assumptions

Survey and Quality Control

•Examination of fabrication quality

•Witnessing of installation

•Witnessing of commissioning

Why Certification in the Wind Industry?

▪ Gain market advantages

A certified wind turbine or wind farm has undergone an evaluation to verify

that it will perform as indicated.

▪ Meet regulatory requirements

Certain countries have specific regulations that only certified

wind turbines are sold in their jurisdiction or that certification

is required for running a wind farm

▪ Earn business deals

Most wind farm developers prefer certified wind turbines and

energy provider prefer being shareholder of certified wind farms

▪ Ensure consistency

Manufacturing and installation inspections and periodic monitoring

▪ create consistent quality over the lifetime of a turbine or wind farm

▪ Mitigate risks

Banks and insurance companies believe in reduced failure due to certification

– Design: site-specific design approval of integrated structural

system of wind turbine and support structure or substation

and support structure as well as foundation or power cables

– Manufacturing: surveillance during manufacturing of project

related assets

– Transport and Installation: surveillance during

transportation and installation of project related assets

– Commissioning: on-site inspections during putting into

operation and related follow ups

▪ Additional modules

▪ After successful finalization of each phase DNV GL is issuing a

– Certification Report describing the assessed components, the

certification activities and the result of the assessment

– Conformity Statement

▪ After successful finalization of all required phases a Final

Certification Report will be issued summarizing all issued

certification reports leading to the

New Markets

25

▪ Offshore wind is now expanding from Europe into

– Taiwan

– USA

– France

– …

▪ This means

– Governmental institutions finding (slowly) their way to

permits for operating an offshore wind farm

– New environmental conditions like typhoons, earthquakes,

rock soil or moving subsea dunes

– Local content in countries with small experience in offshore

structures

– Strong resistance among (local) population

Example: Offshore Wind in France

My experience

▪ French government passed the law for the energy transition in 2014 with an

increase of the renewable energies to 40% in 2030,

will not be reached if not speeding up

▪ Installed onshore wind turbines with 12 GW in 2016

▪ Installed offshore wind turbines in 2019: 2.2 MW = ONE test turbine

▪ Time-consuming permission process leading to an inflexible permit

Example: NO change of the turbine type without starting new permission

process taking about one year

▪ Experienced companies for offshore technology, e. g. Saipem

▪ Good construction infrastructure and know-how for offshore steel and concrete

structures, for marine operation by yards like Chantiers de l’Atlantique

▪ Investors show high interest, e. g. EdF, Engie, Iberdrola

▪ High floating potential and interest
