Predictive Maintenance Talk

turbine rotor is one of critical equipment that have to be lifted and removed during overhaul or turnaround activity. Same like generator rotor removal, turbine rotor removal must be planned carefully and you have to perform several assessment before performing the lifting activity. Overhead crane that will be used for turbine rotor or generator rotor rigging and lifting activity must be inspected, tested and certified.The crane cable sling and the brake must be carefully inspected to avoid abnormal operation. Penetrant test can be performed to make sure that there are no “crack” sign on overhead crane drum and brake. the lifting belt also must be inspected from defect sign and make sure the belt is use within the load chart to prevent turbine rotor incident during removal process.

Failure to do proper assessment during turbine rotor lifting activity will seriously impact your turnaround activity, same like the video that i want to share below, 6.5 million dollar of turbine rotor shaft is broken just in a few second due to crane failure

So, do proper assessment for your turbine rotor lifting and rigging activity to avoid uncertain condition during the activity and it will save you a lot of money because good assessment can avoid you to spend huge amount of money to repair your rotor if your rotor is broken.

For you that influence in turbine generator maintenance, it is nice to know how to perform generator rotor removal  during overhaul activity. Because it is a critical equipment that influence all electrical generation and production, carefully assesment and techniques is a must to perform rotor removal. Fails to do assesment and carefully extraction, your generator stator and rotor will damage and cause a bigger impact on your maintenance schedule and cost.

I have videos that explain the turbine generator rotor removal process, enjoy…..
