Topless Alignment ®

Topless Alignment Services® eliminates the time consuming and expensive process of reassembling the turbine for “Tops-On” measurements, saving hundreds of man-hours and labor per turbine section. Most centerline alignment activities are moved off the critical path, reducing outage duration by days. No “Tops-On” readings are needed.
_
How is Topless Laser Alignment Performed?
_

  • MD&A takes measurements immediately after rotors are removed, during slack time, while the stationary components are waiting for rotors to be blast cleaned.
  • Using custom laser and measurement equipment, MD&A measures turbine shell deflections and centerline bore positions.
  • Ideal steampath bore positions are then calculated and recommended moves are made as a non-critical activity.
  • Final alignment is verified and corrected if necessary, after component inspection and repairs are completed.

Why Choose the MD&A “Topless Alignment®” Method?
_

  • Stationary component alignment is done off the critical path
  • Increased Safety! A 50% reduction in heavy rigging of upper half shells and casings (No Tops-On measurements)
  • Bearing shim changes and pad contact checks done off critical path
  • Improved turbine efficiency
  • Customer focused
  • When combined with the new Guardian® packing from MD&A, the packing can be custom machined to compensate for out-of-round bores, further improving efficiency
