WHITE PAPER:
Innovative Use of a Laser tracker Measurement System in Hydro Turbine and Professional generator Refurbishment

ABSTRACT
An alternative to traditional alignment techniques is being employed during Manitoba Hydro’s refurbishment of its Kelsey Generating Station in order to reduce outage durations and construction effort.

Manitoba Hydro investigated three-dimensional measurement systems before settling on a laser tracker measurement system. The accuracy, repeatability, and the time required to take measurements with the laser tracker system were proven to be superior to traditional methods.

Use of a laser tracker reduced outage time by an estimated 2 to 3 weeks per unit overhaul and allowed the construction team to work more effectively and produce a better result. The laser tracker was so effective that it was used for significantly more applications than originally anticipated.

The laser tracker measurement system can provide savings in schedule and construction effort in both unit rehabilitations and new construction.
