Gas turbine alignment

Gas turbine alignment in less than an hour

The standard functions of the ROTALIGN touch made it ideally suited to perform the alignment of the gas turbines to a steady bearing pedestal despite the large angular thermal growth offsets.

TransCanada Turbines Test Cell repairs and services gas turbines in a unique test facility. The turbines are used primarily for compression, power generation and marine applications. After repair and servicing, the Test Cell undertakes performance tests of the turbines.

In this case, the Test Cell needed to align aeroderivative gas turbines to a steady pedestal bearing prior to the performance test.

The standard functions of the ROTALIGN touch made it ideally suited to perform this alignment task despite the large angular thermal growth offsets and the use of turn-buckles to adjust the inboard end of the turbine.

“The ROTALIGN touch with its larger detector, Move Simulator and ease of use have made the alignments in the test cell that much easier. Given the use of turn- buckles on the inboard end of the engine for adjustment, the ability in the ROTALIGN touch to show both vertical and horizontal adjustments live at the same time is essential.”, states Darren Hall, Test Cell Technician, TransCanada Turbines Limited.
