Wind energy is a dynamic, fast developing technology. Wind energy converters represent highly complex technical systems. Qualified inspections by the technical expert bureau Martin Veltrup make a technically optimal state of a wind energy converter possible as well as a long-term economic operation. A necessary requirement therefore is to indicate damages at an early stage. With more than 20 years of expertise and the usage of state-of-the-art diagnostic equipment, the technical expert bureau Martin Veltrup is your right contact in this case.

From 1998 on, since our technical expert bureau Martin Veltrup is existing, we carry out inspections of wind energy converters and windfarms of various manufacturers in Europe, mainly in Germany. Up to now, we inspected over 7.000 wind energy converters. Among others, we offer the performance of commissioning inspections, periodic inspections, end-of-warranty inspections, condition-oriented inspections, rotor blade inspections, technical due diligence assessments, gearbox inspections including video endoscopies, vibration measurements and analyses, damage appraisals, inspections according to the DGUV (German Social Accident Insurance) regulation 3, drive train alignments as well as the performance of the evaluation and assessment with regard to the extended operation (EAW).

A team with many years experience of working closely together is looking forward to meeting you. For us, short lines of communication and short reaction times go without saying. If it is about making an appointment, planning or questions dealing with a current project, your contact persons are Lena Specht and Kim Janetzke in our consultig office.
