Technical Information Letter #1576
TIL #1576 was issued in 2007 and it discusses
the maximum allowable starts for rotors in cyclic
operation and has a maximum fired hour limit
for rotors in base load operation.
It limits rotors to +/- 200,000 factored fired hours
with some consideration of extensions and/or
5,000 factored starts for a cycle based turbine
with no extensions.
FIRST / TBS
End of Life Testing
FIRST has developed a protocol whereas, after
the rotors have been disassembled, we
inspect specific rotor components using 3D
volumetric phased array bore-sonics and eddy
current.
We perform hardness testing & replications as
well as mechanical testing to inspect the rotors
components for changes and internal or
detrimental flaws. 14

FIRST / TBS
EOL Testing & Computer Modeling TIL 1576 places retirement for rotors with +/- 200,000 hours
or 5,000 starts. After the 2007 TIL issuance, we immediately
developed our team of experts to start testing rotor
components. There is a need to review found critical flaw(s)
to make decisions/recommendations to turbine owners. We
mfg rotor component fracture models to perform F.E.A.
analysis for found critical flaw(s).
By using the flaw size & flaw location, we have the ability to
place those flaws into our computer model to see if the
characteristic of the flaw is detrimental to the continued
running of the turbine. We can accurately determine how
many hours or starts remain in the life of the component
containing that critical flaw.

EOL On-Site Inspections
In 2013, we started performing rotor end of life
inspections on-site.
There are many on-site critical inspection points
that we can perform to assist in determining
where the rotor is along the end of life scale.

EOL On-Site Inspections
As the rotor continues in age, it is critical to
establish early, comparative, base-line data.
There are critical inspections that we can
perform on site to assist us in determining
where the rotor is on the end of life scale.

EOL On-Site Inspections
We can assist end users in setting up an End of
Life inspection protocol with on-site testing so
to provide a clear path on your rotors’ remaining
hours and starts.
This will allow for possible extensions beyond
the current OEM life limitations.
