Availon has obtained the ful HSEQ certification for its operation in the European countries, meaning it complies with quality, environmental and safety standards.
"HSEQ certifications are of rising economic importance for independent service providers. We service wind turbines in Spain and Italy with a total value in the high millions. The certification gives turbine owners the added certainty that their turbines are in competent hands with us, and is an important decision-making criterion for new customers", said Availon co-managing director and CFO Markus Spitzer.
Availon added it hopes to complete its certification of its US subsidiaries this year.
The firm said it services more than 2.6GW of turbines in Germany, Italy, Spain, the US, Austria, Portugal and Poland.
In January, leading turbine manufacturer Vestas announced it would acquire Availon in an €88 million deal. The transaction is due to be completed in early 2016.
It follows Vestas' acquisition of another service provider, UpWind Solutions in the US, completed in December.
