At the beginning of March 2016, HYDRO Exploitation was asked by Forces Motrices de Mauvoisin (FMM) to replace some trunnion seals following sealing problems with the ten DN700 - PN 102 spherical valves (serviced between 2008 and 2013). In order to carry out this work, we developed a special chassis.
In addition to geodetic monitoring for hydroelectric plants and monthly auscultation measuring, our surveyors offer services in the field of metrology and engineering measuring methods. The Farettes facility refurbishment and the ongoing Bramois facility overhaul have benefited from our expertise.
Our mechanical unit has evolved over the years in order to meet the ever-changing demands of the energy market. Our core business is maintenance engineering in hydroelectricity which includes: equipment maintenance, technical support for plant personnel as well as hydro facilities monitoring and optimisation.
