The Legacy Turbine Users Group, formed by Power Users earlier this year to facilitate the transfer of knowledge among members of the 7EA and Frame 5 and 6B users groups, greatly benefits owner/operators of these engines. The 7EA’s first meeting under the LTUG banner, conducted Aug 29 – Sept 1, 2022, was an

Gas turbine systems produce over one-third of US electric energy requirements. They provide reliable baseload power, in addition to that required to support the intermittent production of electricity from renewable sources. According to a recent Washington Post article, “Turns Out Wind and Solar have a Secret Friend: Natural Gas,” every 0.88% of capacity from renewables

Sometimes it’s best to start at the end. During Ethos Energy’s October webinar, “L-0 Blade Repairs,” Ian Saeger, manager of project engineering, concluded by stressing that last-stage steam-turbine blade repair is usually at least 50% less expensive than blade replacement and accomplished within a few weeks—if the repair can be done onsite or in-situ. The

It only takes 2-3% steam overflow to trigger a steam turbine/generator (ST/G) overspeed event, cautioned Dean Casey, project manager for machining services at MD&A, to stress the importance of main-steam-valve inspections and timely repairs. During his presentation in MD&A’s fall series of webinars, “Steam Turbine Valve Outage Common Issues,” Casey went on to say that

MD&A kicked off its fall 2022 webinar series with a presentation on rotor life extension. You’ll want to take an hour and listen in if your plant has a 7F unit approaching 5000 starts/144,000 equivalent operating hours (EOH) or a 7B through 7EA unit approaching 5000 starts/200,000 EOH. Get the background on these requirements in

The underlying message of MD&A’s third webinar in its fall 2022 series is that a shop which has invested in a high-speed rotor balancing (HSB) machine (photo) offers the user clear advantages in shortening outage schedules and avoiding the risk of having to transfer the machine from the shop where repairs are made to a

The Turbine Inlet Cooling Assn (TICA) announces that its annual awards to owner/operators of GE aeroderivative gas turbines who have demonstrated the successful implementation and use of at least one turbine inlet cooling (TIC) technology will be conferred during the 2023 Western Turbine Users Inc (WTUI) Conference (March 12-15 in San Diego). One award will
