Our service division is composed by a highly specialized team of engineers who constantly perform routine and extraordinary maintenance on power plants. We also manage costumed maintenance contracts, depending by the Clients demand as well as by the single power plant needs. The activities are coordinated by the headquarters to organize each operation and be able to guarantee highly urgent activities, with 24 hours availability throughout the whole year.  All personnel are continuously being trained in the latest technology and regulations and it holds every necessary qualification (PES according to regulation CEI 11-27, pent environments, overhead works etc.)

Maintenance assistance contracts


These tests on site take place during regular operation, so as to execute the following activities:

  • Operation test of all the entire rotating machinery.
  • Check of lubrication and control levels with possible topping and grease
  • Setting of a dedicated report with records of significant values, possible causes of arrest and any other observation.


These tests on site usually take place when machinery is arrested.
This operation purpose is to check the correct operation of the auxiliaries and the plant safeties.
All the maintenance activities to use during machinery arrest will be indicated.

Predictive analysis

In order to avoid damage while seeking continuous improvement of our power plants we perform maintenance on each mechanical part, as well as verifying the general performance of the power plant, using the latest equipment and methods according with the current regulation. We annually perform an analysis on the power plant condition using modern equipment while the machinery is operating. It is a normal “preventative maintenance” that is performed to detect the time left before a possible damage and to forecast the components residual life.
For this reason we also verify the total performance of the power system and each part that compose it using the latest equipment and methods according with the current regulation.
