Abstract:
1. A method for controlling the useful life of gas turbines of a production plant including a series of production trains and an auxiliary gas generator group, each production train of said series of trains being in turn equipped with a series of gas turbine groups, each of which in turn includes a gas generator, the method comprising: a) creating a succession of gas generator groups of gas turbines to be subjected to maintenance; b) substituting a first gas generator group of gas turbines of said succession with said auxiliary gas generator group, to keep the production plant functioning with less interruptions; c) inspecting the first substituted gas generator group of gas turbines, by subjecting it to ordinary maintenance operations; d) substituting a second gas generator group of gas turbines of said succession with said first verified gas generator group of gas turbines; e) inspecting the second substituted gas generator group of gas turbines, by subjecting it to ordinary maintenance operations; and f) repeating said steps b), c) d) and e) for all the gas generator groups of gas turbines of said succession until all the gas generator groups of the gas turbines of said production plant have been subjected to maintenance.
