Steam Turbine Diaphragm and Rotor Repairs

Our Midwest Steam Turbine Repair facility in Pevely, Missouri is keeping busy this outage season.  We’ve performed many diaphragm and rotor repairs this spring, and it looks like that will continue for at least a few more months as more steam turbine outages kick-off.  If you have any diaphragm or rotor repair needs during your upcoming steam turbine inspection please reach out to us for an expert opinion and quotation.   Also, at no cost to you, we can send a Steam Path Repair Subject Matter Expert to your site to review components as soon as they become available.  Contact Us today to discuss potential dates for a Steam Path Repair Subject Matter Expert to arrive at site during your outage, or to request a quotation for your potential repair needs.

2021 Alstom Owners Group Conference Presentation

Join us on March 2nd at the Alstom Owner’s Group (AOG) Virtual Conference for our presentation on Steam Turbine Diaphragm Dishing Bridge Repairs.   The AOG puts on a very educational event each and every year, and 2021 will be no different.  Hope to see you there!


Heads-Up! March 5th is Training Day at the 2021 AOG conference

Variety of extended learning opportunities for powerplant end users

One of the distinguishing characteristics of annual meetings hosted by the Alstom Owners Group is its training courses. This year’s program, outlined below, features seven two-hour training sessions on Friday, March 5—all starting at 10:00. A good strategy might be to select the topics of greatest interest and assign plant personnel to monitor each of those sessions; then gather in the break room for a roundtable discussion of the highlights, best practices, lessons learned. Register today at no cost. 

To see details of what the training topics are, and who the instructors will be, please follow this link to the CCJ article:

This year’s conference will be live-streamed globally from PSM’s headquarters in Jupiter, Fla. This location facilitates a virtual tour of PSM’s 105,000-ft² workshop and repair facility, complete with demonstrations at work stations of interest to owner/operators—including blade and vane repairs, additive manufacturing, flow testing, brazing of cobalt and nickel alloys, welding, and machining.

Conference agenda

Monday, March 1. The meeting opens at 8 a.m. (Eastern) with a two-hour user-only session focusing on the repair, service, and maintenance of GT8, GT11, GT13, and GT24/26 engines, with the underlying goal of increasing reliability and controlling costs. The program features formal presentation on the liberation of a GT26 high-pressure compressor blade and instrument failures between C cycles, followed by open discussion.

7EA Combustion Inspections

We recently completed back-to-back Combustion Inspections on two Frame 7EA Combustion Turbines for a major U.S. Utility.  The crew finished the project with zero safety incidents, no quality issues, on-budget, and ahead of schedule.  The customer was extremely satisfied with the results.  Great job by the team that was on-site, and everyone who contributed to the project.  Nice work everybody!


Customer Satisfaction Survey Result

Receiving excellent feedback after a completed project is what makes all the effort worthwhile.  We work hard and continually interact with new and previous customers at facilities around the globe.  The personal aspect of our business is what gives us that determination to make each project a complete success.  There’s nothing better than receiving an excellent customer satisfaction survey at the end of a project.  Here are the results of a survey we received this month, and it really puts into perspective why we strive to be great.  Another excellent job by our project teams!

Beat the Heat!

In our industry, working outdoors in all sorts of weather is part of the job.  Because you can’t stop working when it gets hot, it’s important to know how to protect yourself from heat and what to do if someone on your crew gets overheated.

There are two main kinds of heat illness – heat stroke and heat exhaustion.  Because they require different treatments learn to tell the difference between the two.

A victim of heat stroke has flushed, dry skin; a rapid heartbeat; loud, rapid breathing; and a high body temperature – 105F or more.  The victim may complain of dizziness and headache or may suffer from confusion, convulsions, delirium, or unconsciousness.  This is a medical emergency calling for quick action.  While one person calls for emergency services, others should get the victim cooled off.  Place the victim in a tub of cool water or use a hose or wet cloths to bring the temperature down.  Massage the victims hands and feet toward the heart to stimulate circulation of the cooler blood of the limbs.  Dry the victim off when the temperature returns to normal.  Repeat the cooling process if the body temperature rises again.

A victim of heat exhaustion looks very different from a heat stroke victim.  This person sweats profusely and has pale, clammy skin.  Body temperature is normal.  The victim may feel giddy and nervous, or may vomit or faint.  First aid for heat exhaustion is to get the victim to lie in a cool place and sip cool water.  Loosen the victim’s clothes and call a doctor.  A victim who is unconscious or vomiting will need to be taken to a hospital to be treated intravenously.

Heat exhaustion sometimes includes heat cramps.  This is caused by a lack of salt.  You can relieve the cramps by massaging the cramped muscles or pressing firmly on them with your hands.  If the victim has no other medical condition, you can give half a teaspoon of salt dissolved in 8 ounces of cool water or fruit juice.

Heat-related illness is no fun.  And it’s usually preventable.  Here’s what to do to keep healthy in hot weather:

If you’re not used to working in heat, start out slowly.  Drink plenty of water – at least eight ounces (one glass) every 20 – 30 minutes while on the job.  Drink a nutrient replenishing sports drink with electrolytes.  Avoid alcohol and carbonated drinks, which can cause dehydration and cramps.  Cut heavy, high-fat foods out of your diet and get plenty of rest.  Pay attention to warning signs – if you don’t feel good take a break.

One more thing – pay attention to each other!  You may notice a coworker with flushed skin and rapid breathing before he or she does.  And if he or she must go to the hospital, guess who gets to do his work?

Remember: Hazard Awareness + Hazard Mitigation + Focus = Zero Injuries
