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.”

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
