Why Align?

• Correct bearing loading, reducing vibration & chance of bearing failure
• Correct misalignment caused by turbine foundation settlement
• Minimize rotor stresses due to improper bearing positions
• Prevent new seals from rubbing
  • Consideration for Component distortion
  • Correct Internal misalignments
  • Ensure proper reassembly

  MD&A provides turbine owners with the greatest depth of Topless Alignment® experience in the power generation industry. Our alignment process is a proven technology accompanied by an outstanding record of successful applications on nearly all makes and models of machines.

  The Topless Alignment® Service, or Diaphragm Alignment, starts with the centerline measurements, which were made with “Tops-Off” only. Then the shell horizontal joint distortion is measured & is used to determine centerline component Tops-On to Tops-Off movements. The calculated movements are used as offsets when aligning in the “Tops-Off” condition. This saves any power utility man-hos and reduced outage duration.

  MD&A engineers have successfully aligned over 1700 steam turbine sections using the Topless Alignment® method. Our projects have a remarkable record for “lack of rubbing.” We believe this historical track record of success is an important fact that differentiates our service from those available elsewhere in the industry.

  

  MD&A Alignment Engineers bring both depth and breadth of experience to the turbine deck. Each of our Alignment Engineers performs between 10 and 25 turbine section alignments per year. This depth of experience allows our engineers to constantly sharpen their skill sets and apply some of the most modern techniques available. Our experience base includes successful projects dating back more than 30 years.

  Our Alignment Engineers have the expert knowledge needed in order to interpret the data. They make sure they have valid data for your machine. Each engineer’s broad base of experiences contributes to the overall value we provide as your alignment contractor. You can expect dependable and accurate results every time you hire MD&A to align your turbine.

  Charles Monestere, MD&A’s Laser Alignment Services Manager, said:

  “Our alignment engineers are top in their field. They have been working many years, some decades, on different turbine-generator alignment projects honing their skills. Our alignment team is dedicated and responsive to the customer’s specific alignment needs and does their best to deliver the quality expected and the service when needed. A number of service providers send technicians who just collect data for the customer. Our engineers do the alignment calculations and review options with the customer. Select your alignment engineer / specialist carefully. Not all are created equal!”

Through MAPS or Maintenance Advanced Planning Services, our experts evaluate and organize outage activities, to reduce or minimize outage times, getting you back online fast.

2.     Turnkey Labor

MD&A offers a skilled support team for turnkey installation, maintenance, and steam turbine overhaul services to our clients

3.     Technical Direction

We have experienced technical directors and project managers who provide expert assistance in challenging cases of turbine-generator engineering.  These experts can handle complex technical issues in many different types of OEM equipment.

4.     Topless Alignment

Our Alignment experts use custom measurement and laser equipment for measuring shell deflections and calculating centerline bore positions. This service decreases the expensive and time-consuming turbine reassembly process for “Tops-On” measurements.

5.     Operational Alignment Diagnostics-CMM System

As part of our Steam Turbine Services capabilities the CMM (Coordinate Measurement Machine) system measures and monitors large equipment components and their movements precisely.

6.     Coupling Laser Alignment

MD&A experts can perform a shaft/coupling alignment with Pruftechnik laser technology.

7.     Operating Surveillance Program

This program is useful for monitoring leaks and issues in both steam turbines as well as generators. We would perform this service while the unit is still operating. Plus, we provide recommendations and results based on the analysis.

8.     Field Machining

For use on-site, our team supplies a range of portable steampath repair and field machining equipment. Our experts have many capabilities available in-shop.
