Abstract:
1. A method for maintenance of gas turbines, wherein the gas turbines are disassembled into modules and/or assemblies and/or individual parts, the modules and/or assemblies and/or individual parts of the gas turbines are inspected to determine which modules and/or assemblies and/or individual parts require repair, and repairing the modules and/or assemblies and/or individual parts to be repaired, wherein the repair is subdivided into at least two repair steps, wherein modules and/or assemblies and/or individual parts to be repaired of at least one gas turbine are moved through repair stations adapted for the purpose of carrying out specific repair steps, wherein the modules and/or assemblies and/or individual parts are repaired in different repair lines containing repair stations, with a decision on the repair line to which a module and/or assembly and/or individual part to be repaired will be sent being made after inspection of the modules and/or assemblies and/or individual parts, wherein modules and/or assemblies and/or individual parts of gas turbines are moved discontinuously on a cycle through the selected repair stations or the repair lines, and wherein two or more repair steps are carried out in succession on the same modules and/or assemblies and/or individual parts within one repair line, wherein the modules and/or assemblies and/or individual parts are moved to at least one matched repair station in order to carry out the repair steps, wherein each matched repair station includes two or more identical repair stations provided for at least some of the repair steps, such that the same repair steps can be carried out at the same time on different modules and/or assemblies and/or individual parts within one repair line.
