ACQUIP is trusted by OEMs, Plant Owners and Outage Service Providers to perform their Steam Turbine Alignment. We focus on the internal alignment and rotor alignment of the steam turbine. We have developed procedures, specialized techniques and gained experience for the alignment of steam turbine components. We want you to depend on ACQUIP for the alignment portion of you project.

When we perform steam turbine alignment, we concentrate on quality, accuracy, speed and safety. We know you want your alignment to be performed with a high degree of quality and off the critical path. We currently record internal alignment data with Laser tracker technology into CAD software. This is done for speed accuracy and versatility.
All steam turbine internal alignments employ the same basic process:
- Receive pre-alignment data
- Record as found measurements
- Analyze data with alignment targets
- Move steam turbine components
- Confirm Moves
We determine the turbine axis using the rotor position readings or will build back the machine axis by measuring bearings.
ACQUIP provides the moves in a simple format. ACQUIP works with the Millwrights to ensure there is no lost time due to direction and sign errors. After moves are made ACQUIP records a final set of readings to confirm all components are within acceptable tolerance.
Bearing moves are calculated for the ideal bearing location. ACQUIP calculates the shim changes for bearing moves. ACQUIP will supervise and assist in proper shim changes from each bearing shim pad. After bearing moves are made the bearings are checked for blue contact 80/100 at each pad. After the bearing moves are made, ACQUIP calculates the new rotor position readings.
We measure all internal components:
- Bearings
- Diaphragms
- Blade rings
- Packing
- Seals
- Dummy Rings
- Nozzles

Benefits of ACQUIP STEAM TURBINE ALIGNMENT SERVICES.
- Time savings
- Accuracy
- Other work can go on during the alignment process
- Increased Efficiency
- We take care of the entire alignment process: we take all the readings, enter all the rotor positions, bore presets, Rotor SAG, tops on/off deviation; calculate moves, Give the moves to the Forman or floor engineer, check the alignment was done correctly
- Other measurements are recorded at the same time: Out of round, deformation, bearing elevation
- We can check diaphragm dishing, Rotor deformation, Dimensioning
- We can project shaft alignment position during internal alignment
- We can give you the projected ERAG readings

Working with ACQUIP on the job we had in Italy recently was the best experience I have had in this type situation. ACQUIP was very professional and the response time far exceeded my expectations. The rental equipment was in top shape and made it possible for us to take care of our customer in an emergency situation. We will look forward to doing business with you in the future. Thank you for your hard work.
ACQUIP’s engineers performed a great job for Siemens Energy . The Fluid Drive and Gearbox and Pump were all included in the task. Each component was aligned to “all” of Siemens procedures and specifications requested. The Siemens customer was very satisfied with the results of the alignment and process.
First I would like to thank you for your help. We need a piece of alignment equipment on site last minute do to a break down. ACQUIP responded to your request immediately, recommend the right tool for the job, and had the tool on site by 8:30 AM the following morning. Just outstanding customer service and support from the entire ACQUIP team.
ACQUIP was the best choice to rent the Laser Tracker. It speeded up the process! I will definitely come back on our next set of fixtures!
I highly recommend ACQUIP for executing both Tops on/Tops off and Tops off Steam path alignments.
