WIND TURBINE CERTIFICATION PROJECT CERTIFICATION

Statement of feasibility

Prototype

Provisional TC

TC

5 years

Site specific design assessment

Design evaluation

Warranty

What are we doing during the design evaluation? • D-Design Certification based on plausibility checks on the conceptual design documentation • C-Design Certification demonstrates that the wind turbine is sufficiently documented for the prototype stage in the development of a new wind turbine type • B-Design and A Design includes a complete assessment of the wind turbine design documentation

The investment into a certified fire protection system offers not only financial benefits by minimizing risks; it also protects the operator and manufacturer of wind turbines from grave image damages by preventing burnt-out wind turbines.

Maintenance

“With the certification of our fire protection system ‘Siemens AFFS’ performed by DNV GL, the risk of fire spread in the wind turbines is greatly reduced.” Benno Rupp, Siemens

Start thinking about lifetime extension early on • DNV GL’s lifetime extension services maximise the profitability of your ageing wind farms • DNV GL provides tailored solutions for all needs – Our services contribute to the financial stability needed to maintain a wind farm and can be relied on from the start. Please ask Klaus-Georg Hansen for more information: +49 40 36149 4092 / Klaus-Georg.Hansen@dnvgl.com

“DNV GL’s expertise was a big help to achieve this important milestone in our product development. We were impressed by the versatile and professional cooperation.” MITA Teknik

“Extending wind turbine operation beyond the original design life without additional risks for health, safety, environment and grid integration, is of huge benefit to the renewable energy industry. DNV GL’s certification supports our efforts in maximising the lifetime of our turbines and optimise its continuous operation.” Sergio Vélez (Director of Lifetime Extension) Gamesa

DNV GL can support you with the certification of the Condition Monitoring System (CMS) which intends to monitor drivetrains with a special focus on gears and bearings. It ensures a condition-based maintenance which helps you to enhance availability, predicts maintenance schedules and detects damages in your wind turbine operation. Robert Kasch is happy to help: +49 40 36149 6744 / Robert.Kasch@dnvgl.com

Testing

10 years

During the testing phase, accredited labs are performing component and full prototype testings for the manufacturer. The results will be subsequently verified by DNV GL. Our certification of service and maintenance activities provides trust in the quality of the certified service and maintenance. It results in competitive advantages for service providers and operators as well. Interested to find out more? Manuel Gemünd +49 40 36149 4066 / Manuel Gemuend@dnvgl.com

The manufacturing certification module aims to verify that the wind turbine components and systems are produced and tested according to the documentation received. It is based on evaluation of documentation used in the production as well as certificates and other delivery reports from sub suppliers.

A DNV GL Shop Approval is a type-independent certification focusing on the manufacturer's ability to build wind turbine components in compliance with DNV GL's standards and guidelines. In case of questions, please get back to Kay-Uwe Fruhner: +49 40 36149 918 / Kay-Uwe.Fruhner@dnvgl.com

Development Accompanying Asssessment (DAA)

Development Accompanying Assessment (DAA) For wind turbines, certification is the key to ensuring product quality. But many manufacturers underestimate the time required for certification – which can delay their market entry. Start thinking about DAA if…

1

.. certification is new for you

2

.. you need support in finding your way through standards, guidelines and norms

3

.. you have a very tight timeline in your project
