TG408 – Turbine Water Induction Awareness

2 days - 14 PDH Credits Awarded


No future dates scheduled


It’s back!  In the 1970’s water induction was a serious industry problem.  Experts from all parts of the industry came together with a plan on how to avoid a water induction occurrence.  Many (most) large utilities put this design practice into place.  By the late 1990’s however, the number of water induction events were again on the rise.  Why?  Well there are many answers to this question, and this course addresses each of them.  Learn to avoid the possibility of experiencing a water induction incident.  This course reviews the latest ASME recommendations in detail.  This review includes power plant design issues, instrumentation for detection, and operator action.  Class presentation includes relevant case studies that demonstrate just how quickly we can get ourselves in trouble if operating recommendations are not followed.  Class presentation includes sample results (at several plants) where a water induction risk assessment was conducted.  The results (of both case studies) might surprise you (they do us). Topical Outline includes:  Overview of how a turbine might be damaged, Design Recommendations, Incidents, Detecting the Presence of Water Induction, Operation to Minimize Damage, Operating Recommendation, Tests, Case Studies. This course is recommended for engineers, shift supervisors, operation superintendents, watch engineers.


Upon completion of this course the participant should be able to:
  1. Describe recommended design practices that have been initiated to protect turbine equipment from water induction.
  2. To list instrumentation typically available for detection of a water induction event.
  3. Given an alarm situation, describe what corrective action should be taken and why.
  4. Describe what type(s) of damage might occur as a result of water induction.

Frequently Asked Questions

  • Will HPC Technical Services bring this course to our location for our personnel only? YES, call or email Stephen Parker, for a price quotation.
  • Will HPC Technical Services customize the presentation at our site to suit our particular needs?
  • Is HPC Technical Services' textbook available for purchase as a reference document? No, we wish to not distribute the case studies used and other materials can easily be researched thru ASME.
  • What is the cost for HPC Technical Service to deliver this course at our location? Well, of course that can vary, but generally speaking, if you're planning on having 6+ attend, when considering your T&L, it is to your advantage to perform the course at your plant (office).  You gain from the customization and price.
  • Can HPC Technical Services perform a water induction audit of our operating procedures, maintenance procedures, design and instrumentation? Yes we can.  Call or contact Stephen Parker, for our rate sheets and any further information required.

Steam Turbine Maintenance Certification

Those who attend this course are automatically qualified to take HPC Technical Services' Certification Examination.  This examination is offered at no additional expense to the participant.  An 80% passing grade is required.  The examination length will not exceed 2-hours.  Those who complete this examination will receive a revised "certificate of completion" that recognizes this accomplishment along with two-copies of a "To Whom It May Concern" letter that states their accomplishment.  (Two copies are provided, one for the participants' employer and one for the participants' personal file.)  Consult HPC's website,, for detail on this certification program.

What you will receive

  1. 1 copy of HPC Technical Services' textbook, Turbine Water Induction Awareness as written by Harold Parker.
  2. A Certificate of Completion with 14 PDH awarded.
