Spring 2022 Webinar Series

Webinar Series 2022 | Operational Expertise to Troubleshoot Difficult Operating Issues

Operational issues can arise during unit operation which can affect performance or lead to a forced outage. To keep you running and help address these operational challenges, MD&A leverages the diverse experience of our engineers and Subject Matter Experts (SME) to help guide you in your gas turbine-generator or steam turbine-generator issues. We are your full-service, OEM-alternative!

Webinar 1: Turbine Valve Actuator’s Operational Issues and Upgrades
Date/Time: Tues. Feb. 15th, 2022 from 11:00am—12:00pm ET
Speaker: Anthony Catanese, Manager of Business Development and Commercial Operations for MD&A Bearings, Seals and Hydraulics

Operational issues are never fun but the key is proper preventative maintenance.  Modern Turbine Valve actuators have evolved from the legacy EHC actuators of the past.  Modern actuators do require more attention and maintenance than it’s predecessors. We will discuss and review some best practices to extend the maintenance intervals and some common operational issues ( Ex/ weeping/leaking, broken springs, defective servo or solenoid, etc…) with different OEM designs.

Key Takeaways:

  1. Know when your actuators need to be maintained?
  2. What parts should you stock?
  3. What is typical/expected damage?

Webinar 2: Gas Turbine Fuel Nozzle Flow Issues
Date/Time: Thurs. Feb. 17th, 2022 from 11:00am—12:00pm ET
Speaker: Joe Palmer, General Manager of MD&A Fuel Nozzle Services & Pat Murphy, Director of MD&A Fuel Nozzle Services

Combustion Fuel nozzles are a vital component of a gas turbine engine.  Many owners and operators realize the importance of paying close attention to fuel nozzle maintenance specifically the tight flow tolerance of a complete set of fuel nozzles in gas turbine engine performance.  Owners and Operators who fail to understand the impact fuel nozzle maintenance have on the rest of the system often experience an increase in overall costs and a decrease in total performance. Improperly maintained fuel nozzles, not properly balanced (flowed), can also have adverse effects on the life of the HGP components and major components such as the rotor, buckets, blades, and vanes. In addition to the increase in outage costs, the potential of lost revenue resulting from the extended outage or de-rating the unit may also occur.

Key Takeaways

  1. Improved start-up and tuning of turbine after overhaul
  2. Reduced temperature spreads that lead to flashback/lean blowouts and derating of the turbine
  3. Customers identify or eliminate potential fuel nozzle issues as part of their overall turbine operating issues using in situ portable test stand

Webinar 3: Troubleshooting Alarms & Trips With High-speed Data Capture using the Trender/Trend Recorder Feature
Date/Time: Tues. Feb. 22nd, 2022 from 11:00am—12:00pm ET
Speaker: Joe Clappis, Senior Engineer for MD&A Turbine and Generator Controls Division

High-speed data is very often essential for root cause analysis troubleshooting of turbine operation; once-per-second data is most often insufficient. The emphasis will be on the high-speed data capture capability of the feature for troubleshooting alarms and trips. Exporting data to be analyzed using MS-Excel will also be explained. High-speed GE® exciter data can also be captured using Trender/Trend Recorder. And, this topic applies to any application of Mark VI or Mark VIe (GT; ST; BOP/DCS). If the GE® Mark V HMI uses WorkstationST Trender/Trend Recorder can also be used for legacy Mark V turbine control panels.

Key Takeaways:

  1. Using the high-speed data capture and analysis capability built-in to Mark VI Trend Recorder or Mark VIe Trender
  2. Configuring triggered trends for intermittent high-speed data gathering
  3. Exporting high-speed trend data to MS-Excel

Webinar 4: Generator Retaining Ring and Main Lead Failures, Case Studies, and Repair Methods
Date/Time:  Thurs. Feb. 24th, 2022 from 11:00am—12:00pm ET
Speaker: James Joyce, Operations Manager for MD&A Generator Division

MD&A generator would like to present proper inspection methods for main leads and retaining rings.  These methods will include proper inspection when the unit is assembled and disassembled.  In addition, we will dissect different types of failure mechanisms of main leads as well as retaining rings.  Finally, we will conclude the presentation with multiple case studies on both retaining ring and main lead failures

Key Takeaways:

  1. How high cycle fatigue can damage main lead components and how to properly prevent reoccurring damage
  2. How to properly inspect retaining rings and main leads when the unit is assembled and disassembled
  3. Case studies that demonstrate if proper maintenance isn’t occurring what that damage could lead to

In our 40 years, our commitment to excellence has earned customer trust for all turbine-generator needs. We focus on delivering consistent quality and value with fast response, superior communications, and innovative solutions.

MD&A is easy to work with. We provide immediate access to expert help when you need it, where you need it. Around the corner or the globe, we ensure prompt, thorough communication and follow-through. For every repair job, large or small, the speed and effectiveness of our response team is matched only by the depth and breadth of our engineering expertise.

Find out today why so many power generators use MD&A to maximize operational effectiveness.
