Troubleshooting
TG Advisers has the expertise to
troubleshoot a wide variety of turbine
and generator operating issues including
vibration, performance shortfalls, and
chronic mechanical failures.
Failure Analysis
TG Advisers is versed in several format
failure analysis techniques. We typically
use the Kepner Tregoe process for most
probable root cause failures. Depending
on your needs we can participate,
facilitate, or lead a formal failure analysis
process. In addition, our company
offers a full range of materials’ testing,
examination services, and finite element
analysis. We also have a well-renowned
metallurgist on staff to support failure
forensic assessments.
TGA is a network of experts with extensive OEM, utility, and engineering consulting experience who have designed units
operating worldwide, developed novel service strategies, and engineered major unit upgrades. We saw a need to provide
independent advice to the power industry in today’s challenging environment and combined our efforts to form TG Advisers.
A description of our core services follows.

Turbine-Generator
Health Assessments
Our process provides a method to
identify high failure risk areas and
also optimize outage intervals based
on actual machine condition. Recent
inspection reports alone will not allow for
the most effective planning since many
failure modes are time dependent and/or
chronic in nature. Through our Turbine
Generator Health Assessment Process,
we conduct interviews with operations
personnel, review available inspection
reports dating as far back as unit
commissioning, and incorporate detailed
knowledge of the design basis and
materials with critical service issues into
a risk-weighted action plan for the next
outage along with a 10-year budget.
TG Advisers has completed more than
350 plant assessments including fleet
programs at NRG, FirstEnergy, Emera,
Nova Scotia Power, and all nuclear units
in the US, Spain and Belgium.
Plant Due Diligence
Assessments
Many of our clients are actively
purchasing and selling units
around the world. Together with
our assessment process, we can
provide a comprehensive review of
a unit, including its environmental
condition, operating structure, and
profitability thereby supporting any
buy or sell evaluation for your firm’s
consideration. Sometimes fatal unit
flaws in a power plant’s operations
are not recognized by teams who do
not have the advantage of possessing
the technical depth of our TGA team.
We have combustion, balance of
plant, environmental, and turbine
generator experts who can quickly
assess a unit and provide realistic
operational, maintenance and capital
outlay projects for the long term.
Plant Heat Rate
and Performance
Assessments
Is your plant short on capacity or
has the plant’s fuel consumption
taken a turn for the worse? Let the
TG Advisers’ team evaluate the
current performance state of your unit
and recommend repairs or testing
to capture lost generation.
Plant Upgrade
Assessments
Many on our team have developed
both reliability and performance
upgrades operating well over 35
years. Our team can help assess your
unit and provide options to address
more aggressive merchant plant goals
for reliability and output.

Reviews
A structured technical review with an
experienced and unbiased third party
is an excellent method to mitigate
risks. If conducted early in the planning
process, such an evaluation can be
used to identify areas which should
be addressed through contractual
requirements. Weak points where an
independent assessment should be
conducted can be incorporated into the
project schedule. TG Advisers
has more than 30 years of OEM
design and repair experience on both
fossil and nuclear applications. The
TG Advisers’ team offers a proven
design review process to identify
design weaknesses up front and
address concerns before major
commitments are made.
Torsional Vibration
Testing & Analysis
TG Advisers is a recognized industry
expert in torsional assessment and
testing of complete turbine generator
trains. Torsional vibration failures
have been recognized by the industry
as one of the leading causes of
catastrophic unit damage resulting
in outages which have extended
more than six months and resulted in
claims in excess of $500M. The TGA
team can evaluate your risk profile
and assess the need for testing and/
or modification. Our team has over
35 years of experience in this highly
complex failure mode.
Technical Training
TG Advisers is a known global leader
in providing targeted steam and gas
turbine generator training. Our 40
plus years of design, troubleshooting,
and operating experience in the
power plant industry translates
into training modules with proven
solutions for the prevention of failures
on your units. We can customize our
training to meet the needs of your
facility and can offer onsite locations
of your choice.

Improved Start Times
Many of our clients have units that
are struggling to achieve online
opportunities and associated
revenues. Our team is well versed at
modelling and assessing your current
startup procedures and providing
methods to significantly reduce these
time periods. In some cases, start
times have been reduced by 30 to
40% allowing key assets to participate
in a merchant environment at a much
higher participation rate.

shop for repair or manufacture? Is
your job one of many being worked
on in the facility? TG Advisers can
provide independent shop surveillance
services to ensure critical repairs/new
unit work is completed to specification

Outage Cycle
Optimization

how millions can be saved by
transitioning from a fixed schedule
of major outages to a customized
schedule of smaller component
focused outages. Cycle outage
optimization not only results in a
more suitable inspection regime
but also provides significant cost
savings.
