In general, each system is designed for a specific life span. These are for example 30 years for a wind turbine, 35 years for a heating system an 70 years for a multi-storey car park. Naturally a system has to be maintained and even in high quality products failures are not inevitable. Depending on the state of degradation, different maintenance actions are required.<\/p>\n<p><a href=\"http:\/\/141.23.68.248\/wp\/wp-content\/uploads\/2020\/01\/Rplot.jpeg\"><img loading=\"lazy\"
