Customer Story: E.ON Climate and Renewables Offshore Wind Farm Undergoing Certification
E.ON Climate & Renewables is responsible for E.ON Group's global renewables and carbon sourcing activities. Its Amrumbank West (AWG) offshore wind farm is being constructed in the North Sea. SGS is acting as the project’s certification body.
The wind farm is located in the German Exclusive Economic Zone, about 35 kilometers west of the island of Amrum and 35 kilometers north of the island of Helgoland. It will consist of 80 offshore wind turbines with a total installed capacity of 288 MW. An offshore substation will connect the turbines with the mainland grid.
Intensive review required
The project requires the investment of a large amount of resources and raises the possibility of safety and environmental risks. Therefore, the German administration (BSH) requires every phase of the project, from design to commissioning, to undergo review and certification.
E.ON Climate & Renewables needed a partner it could trust. In 2010, E.ON Climate & Renewables hired SGS as the certification body, based on its experience in the wind energy sector, its highly qualified inspectors – who include experts in several engineering disciplines – and its ability to support clients anywhere in the world.
SGS’s contract covers:
- Design review
- Onshore manufacturing
- Load-out, transport, installation and commissioning of the wind turbines
SGS is responsible for:
- Factory inspections
- Visual inspections of components
- Monitoring of transport and offshore installations
- Witnessing of tests
- Document reviews
Inspections in process
SGS began work in 2011 and has, to date, certified the design of the wind farm’s components. Inspectors from SGS Germany, SGS Poland and SGS Belgium are now performing inspections for the execution phase. These include:
- Steel manufacturing surveys
- Corrosion protection surveys
- Reviews of mechanical and electrical components testing
- Surveys during offshore transport and installation
- Commissioning surveys
Throughout the project, SGS has demonstrated flexibility in the face of unexpected changes – such as a last minute change in the installation method – enabling milestones to be achieved on time.
SGS’s role is expected to end in the second half of 2015. By that time, about 75 SGS experts will have been involved with project certification to ensure the AWG offshore wind farm is completed successfully.
