Estimating the term…
The present invention proposes the use of the shearography technique in a system for the non-destructive inspection of composite material repairs applied to submerged metallic pipelines. The shearography system of the invention is characterized in that it comprises at least one vision and lighting module (VLM) (1), at least one fixation module (FM) (2), at least one excitation module (TEM) (3), at least one command and power module (CPM) (4), and a computer (5). The proposed system can be fixed to the repaired pipe by means of divers or ROVs, and the inspection control can be carried out entirely from the platform or surface support vessel.
