Check before end of warranty for wind turbines

Find damage on critical components and don't let warranty claims expire. How? With an inspection by ENERTRAG Operation before the warranty expires.

When financing wind turbines, operators and banks assume a term of at least 20 years. Defects from the commissioning phase should therefore be identified at an early stage within the defined warranty entitlement and rectified by the manufacturer. Our Check before end of warranty for wind turbines helps you to identify defects and subsequently claim them from the manufacturer.

5 good reasons for a check before end of warranty:

• You ensure that your wind turbines do not carry any unidentified defects from their first years of operation
• You can claim warranty from your manufacturer so that they can perform any necessary repairs at an early stage
• You reduce the risk of increased maintenance costs after the end of the warranty period
• You receive a reliable instrument to compare the delivered status quo with the contractual agreements
• The check before end of warranty can of course also be used as the first periodic inspection 

Our goal is to operate wind turbines as safely as possible. To ensure this goal, our qualified specialists carry out tests on wind turbines according to your individual wishes and needs and in accordance with the guidelines of the German Institut für Bautechnik(DIBt guideline).
