TÜV Rheinland to surveil Senvion rotor-blade production

With its beginnings in orchards, this company has returned to its green roots by machining large parts for the wind-power industry.


TÜV Rheinland has been commissioned to perform comprehensive testing on behalf of Senvion, a manufacturer of wind turbines. The experts will surveil the production of rotor blades for the Trianel Windpark Borkum II offshore wind farm. In the process, they will check that the blades conform to the production documents, that the rules of technology are observed, that specific quality requirements set down in the specifications are met, and that deadlines are observed.

The experts from TÜV Rheinland also will examine the documentation. This is not the first commission of its kind for the internationally active certification service provider. After successfully completing a production monitoring order for rotor blades in Castellón/Spain for the Nordgründe and Nordsee One wind farms, TÜV Rheinland has now been commissioned to surveil the blade production in Portugal as well.


The Trianel Windpark Borkum II wind farm is being developed 45 kilometers to the north of Borkum in the German North Sea as the second stage of the Trianel Windpark Borkum, a wind farm that has been operating since 2015. After completion, which is planned for autumn 2019, it will have an output of around 203 megawatts. It will contain 32 turbines from the Senvion 6.XM series.

Senvion is a leading global manufacturer of both onshore and offshore wind farms. The international engineering company develops, produces, and operates wind farms for almost any location — with a rated output between 2.0 and 6.33 MW and rotors ranging from 82 to 152 meters in diameter. Senvion also offers its customers project-specific solutions in the fields of turnkey solutions, service and maintenance, transport and installation, and foundation planning and construction.

TÜV Rheinland is accredited by DAkkS, the German accreditation body, as a certification organization for type and component certification for onshore and offshore wind turbines according to national and international standards and is listed as an RE Certification Body by the IECRE. The company offers ambitious services such as location analysis, geotechnical exploration, and verification of structural analysis but also manufacturer monitoring, quality inspection, and construction monitoring. As an inspection body accredited by DAkkS according to DIN EN 17020, TÜV Rheinland offers wind-turbine operators recurring and state-oriented testing, digitally assisted assessment of system conditions, and special examinations by means of the latest destruction-free test methods. Special location reports, due diligence investigations, and yield forecasting in turn serve to secure investments.
