Specialised services
Specialised services
We offer specialised services to support operators in the maintenance and servicing of their facilities.
Underwater Inspection
Underwater inspection enables owners of hydroelectric schemes to ascertain the state of the underwater parts of their projects (silting, disorder in the concrete and mechanic elements, etc.), by penetrating both depth and visibility. This benefit applies to the following works :
Multibeam and single beam bathymetry
Bathymetry enables topographic measurements to be taken of submerged areas of lakes, réservoirs and watercourses.
Cleaning with CO2
Regular cleaning of electrical machines prevents harmful external pollution which can lead to Failure and ultimately loss of production.
Transformer oil treatment
The treatment of transformer oil is an important maintenance operation in the life of a transformer.
QES Services
We have developed our own know-how in the fields of quality, environment, safety, documentation and archiving.
Training
We offer ”avalanche“ and ”difficult terrain“ courses whose main objective is to teach employees how to estimate the real danger of a given situation.
