Technical expertises / Inspections

The focus of this assessment lies in the condition and operational safety of the wind turbine. As members of the Advisory Board, we issue a certificate of attestation in addition to the report, which has been agreed with the authorities.

Commissioning reports are in principle an extended periodical inspection report with ZOP of all installed components with verification of contractual obligations. In addition, it is checked whether technical equipment and the documentation meet the requirements of the approval certificate.

Rotor blades can be examined in the first step by drone flight for any damage. In the case of a recognizable damage this can be repaired by rope technique or by working platforms.

Based on the Real Estate Valuation Regulation, we determine economic success and risk factors as the basis for a profitable investment.

With heat flow thermography, structural defects in rotor blades can be determined. For this purpose, the blade surface is briefly heated, so that a heat front diffuses into the interior of the sheet. If it encounters a bad heat-conducting due to delamination or defective bonding, the surface can not cool down so quickly over this defect and appears in the thermal image as a warmer area.

This report is often a prerequisite for the acceptance of the wind farm from the OEM and at the same time a defect report. It shows the owners the points still to be worked out and serves as a basis for the retention of final payments or contractual retention.
