for potential cost reduction of the repair process – resulting in overall maintenance cost reduction. Alongside the benefits to its own repair process, Siemens can now offer its customers strategic advantages: Through the new process, the experts are able to make improvements to the turbine technology relating to the component by building them into the repair process. In this way, operators could have access to the latest technology, even if their turbines have seen years of service. Dr. Vladimir Navrotsky, Head of Technology and Innovation at Siemens Energy Service, Oil & Gas and Industrial Applications, summarizes: “With this new repair technology we are looking to carry out these high precision jobs much more quickly.” It’s not only the Swedish Siemens’ subsidiary that views the project as a significant achievement. “We have successfully pushed our technology into the repair arena. We have shown that we are capable of modifying our system quickly to meet customer-specific requirements. In this case, the modifications to both hardware and software were significant. Everyone involved can look back with satisfaction, not only at the end result but also the route to achieving it,” says Stefan Oswald from EOS.

Facts Short Profile Siemens Industrial Turbomachinery AB manufactures, installs, commissions and services industrial gas turbines with a power range of 15 to 60 megawatts. Address “Additive Manufacturing opens up new dimensions for us in the use of integrated design and production. This technology enables us to manufacture and repair components for our industrial gas turbines far quicker than before. At the same time, the functionality and performance of the part is increased.” Dr. Vladimir Navrotsky, Head of Technology and Innovation at Siemens Energy Service O&G Siemens Industrial Turbomachinery AB SE-612 83 Finspong Sweden Challenge Customising an EOS solution for the precise, cost-effective, and faster repair of gas turbine components exposed to extreme temperatures. Solution Enlargement of the construction capacity to accommodate individual customised repairs through the reapplication of material to the worn burner tip of the gas turbine. Results - Fast: time required for the repair process of burner tips has fallen by more than 90% - Innovative: old versions of the burners can quickly be brought up to the latest standards of technology - Cost-effective: potential cost reductions already seen at an early stage Issue 15 PECM 7
