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:

March 1-5. Open to all powerplant owner/operators. Register today!

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).

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.

On-Site Turbine Repair Services

If it is beneficial to you to have turbine component repairs performed on-site, we offer our portable equipment to be ready when components are removed from the turbine.  Contact us today to reserve our portable repair equipment for your next turbine outage.

We are ready for your Journal and Shaft Machining Projects this outage season!

We have successfully repaired thousands of shafts and bearing journals in power and industrial facilities across the globe over the past 25 years. Our unique, on-site machining process requires absolutely no need for shaft rotation, and avoids the issues related to removing and shipping equipment to a shop: costly mobilizations, exorbitant shipping costs, potential damage during shipment, valuable lay down space, and plant crane and rigging requirements. Our finely tuned and safe processes coupled with a full range of equipment ensure customers receive the highest quality at a competitive price. If you have a journal or shaft machining project, planned or emergent, please contact us 24/7/365 for a fast response.

In-House Gas Nitriding

We have in-house nitriding capabilities to provide you with a quick turnaround of your critical components.  Gas nitriding is a surface hardening process, where nitrogen is added to the surface of steel parts using dissociated ammonia as the source. Gas nitriding develops a very hard case in a component at relatively low temperature, without the need for quenching. As a result, a very high strength product with extremely good wear resistance can be produced, with little or no dimensional change. For valve components, these material enhancements translate into increased durability and service life and ultimately, reduced maintenance cost.  

Please contact us today to discuss when we could nitride your component and how we can expedite all of your future component nitriding needs.   We have the capability to nitride around the clock, providing you with more opportunities to nitride your components at a schedule that is convenient for you.  Our nitriding oven can accommodate components up to 38″ in diameter and 100″ in length.

We look forward to working with you for all your critical component needs.
