OPINIONS
”We see the model as a tool to
achieve the best possible efficiency
for the turbine plants.
The turbine operators use the
model daily to trend the efficiency
and to counter any reductions.”
Magnus Kruse,
turbine operation

What value do you see with the digital twin of the turbine plant?
”In my role as operation manager I
can track the performance of the
plant and react to changes in the
process to prevent any production
losses.
”In short, we have benefited greatly
from the model.”
Olafur Olafsson,
operation management

”At several times the models have
been very useful for detecting
faults in the plants in an early
phase. The early detection of faults
means that it is easier to plan and
perform necessary repairs.”

specialist turbine analysis
