With the Facility for Antiproton and Ion Research (FAIR), an extension of the existing accelerator facility is being built at the GSI Helmholtz Centre in Darmstadt/Germany, which will increase the area of the research center by a factor of four. Within the framework of the project, a superconducting 100 Tm synchrotron, a superconducting fragment separator and 2 storage rings, as well as several kilometers of beamline and target stations are built. With the increased complexity and the number of devices, the possible sources of failure also multiplied. It was therefore necessary to keep reliability in mind from the very beginning and to develop a corresponding concept for the operation and maintenance of the facility. In this talk, the concepts are presented and a short status update on the state of the project will be given.
