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.
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!
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:
The steering committee for the fourth annual Alstom Owners Group (AOG) Users Conference welcomes participation by all owner/operators of gas and steam turbines in this year’s event, March 1 – 5. The majority of sessions from Tuesday (March 2) to Friday feature content pertaining to most types of turbines (see agenda below).
First step in securing your invitation is to register at www.aogusers.com; this only takes a couple of minutes. There is no registration fee. Questions? Contact conference coordinator Ashley Potts by email.
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.
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.

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!
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!

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
We’ve recently re-painted some of our tool containers – and they are looking good. Nice work by our team at our Knoxville, Tennessee Logistics Center.
PSG maintains fully configured containerized tool sets, ready to be shipped to your location at a moment’s notice. The entire tool set fits on a single truck bed for ease in transport. Our logistics team is ready to ship these tools to meet your need – using best available rates for pre-planned outages, or expedited using 24- hour driving teams for emergencies.
Once we arrive at your site, we can quickly mobilize to efficiently begin work on your outage. If space and crane capacity is available, we can lift a container to your turbine deck and roll out our tool cabinets. If space is tight, we can lift the individual cabinets into place or transport them by forklift.
Our Project-Specific Planning allows us to customize the tool set for the job. We have what we need on-site, even planning for contingencies. The more organized we are, the more efficient our project teams can be, and that means less downtime for you. Our fully-equipped trailers focus on safety and reduce labor costs so we can get your unit back online efficiently.
Specialized for Specific Needs
Besides Major Inspection tool sets we have developed many other customized sets including:
Major/Minor/Valve & Bearing
Organized for Efficiency
Our tools are organized for efficiency. Small tools are organized in movable heavy duty cabinets, with each drawer labeled in large letters. Tools are organized in foam cutouts within the drawer to make it easier to locate and replace a tool – a specific place for a specific tool. Large tools are organized in Gang Boxes, with hooks or pegs labeled for every tool.
We have a standardized arrangement for all our tool sets, so if a mechanic is familiar with one, he is familiar with all. Our mechanics take pride in our tool sets and retrieve and replace their own tools, as required, so there is no need for a tool attendant. This increases productivity and makes sure the right tool is used for every task.
We bring a dedicated office trailer to facilitate project planning and communications. The trailer contains lights, power outlets and printers for management support, and is fully supplied with materials for lockout, badging, reporting and other support services.
After the tool boxes are removed from our separate tool container, it is used as a break room for our mechanics.
If turnaround time is a critical factor in your outage, then we can perform most all machining and rotor repair using specialized portable equipment delivered to your remote facility. We will work with you during pre-outage planning to determine if this option is right for you.
On-site tooling is available for Rotor/ Seal Turning
Low Speed Balance
Broken Bolt/Stud Removal
Generator Rotor Rewind Collector Ring Grinding
