Maintenance, Repair & Overhaul

Research project Change in production technology

What it is about

Maintenance, Repair and Overhaul refers to the classic maintenance and repair business used to repair components, plant and machinery. Typically, this is done through static repair process chains in which the same value-added steps are carried out continuously. After repair or maintenance, the systems and machines continue to operate with identical characteristics.

Goals of the research project

The aim is to develop new technologies for maintenance and repair activities which simultaneously mean an upgrade, i.e. an improvement in the properties of the component. Improved properties in turn lead to higher efficiency and lower emissions.


The use of future technologies such as digital solutions or additive manufacturing processes can lead to product and process innovations that enable the operating intervals to be extended. Within the Werner-von-Siemens Centre, components, plants and machines are no longer to be repaired in the classical way, but are to be equipped with better properties through new technologies during the repair: Upgrade instead of repair.

To this end, new dynamic process chains are being developed in which the value-added steps are specified through digitisation. Each component should pass through an individual repair chain This development is to be demonstrated using the example of gas turbine blades, which can be operated at higher temperatures or longer operating intervals after repair.

Maintenance, Repair & Overhaul • Research project Change in production technology
Project launch: July 2020 • Funding amount: 10,2 Mio. € • Number of partners: 9 • Satellite Nonnendamm


In the newly built production hall of Siemens Energy, research will in future be conducted on repair and maintenance topics. The hall is located at Nonnendamm, an external site of the Werner-von-Siemens Centre, near Siemensstadt.
