Turbine Removal: Use of Ball Bearings to Assist Stata Removal

Removal of the old rotors from the main gensets had proved very time consuming with quite high level manual handling risks. Using some creative thinking, the team found that a small gap could be created under the rotor into which temporary bearings could be placed for ease of removal

The team had to remove the Stata from the centre of the Turbine, this was drawn out using the overhead gantry crane, The Stata was snagging during the removal process making the task difficult and the Stata problematic to manoeuvre.

The resourceful team had the idea to skate the Stata out on bearings to ease the process, they found that by lifting the Stata up to make a gap they could place some bearings in which when lowered the Stata would sit on allowing this to simply roll out with the overhead crane support.

The simple process saved crane time (and fuel), man hours and reduced manual handling.
