Structural reinforcement of a rotating equipment base
Diagnosis of excessive vibration and reinforcement of the base, with alignment and levelling corrected.
Execution
The sequence applied and the engineering decisions taken
The order below reproduces how the work was actually carried out, including the points where the condition found required a change of scope.
- Vibration measurement and assessment of the base, which had lost stiffness and had degraded grouting.
- Site survey and design of a reinforcement compatible with the space available and with maintenance access.
- Reinforcement elements manufactured in the workshop, cutting the time worked in the operating area.
- Strip-down of the set, fitting and welding of the reinforcement with distortion control.
- Degraded grout removed, base regrouted and levelled.
- Reassembly, alignment of the set and controlled torqueing of the holding-down bolts.
- Supervised start-up with vibration re-measured and compared against the initial condition.
Comparison
Condition before and after the intervention
Drag the slider to switch between the two recorded conditions.
- Before
- Vibration above the limit, degraded grouting on the base and repeated bearing failures.
- After
- Base reinforced and levelled, set aligned and vibration within the acceptable band.
Result
What the intervention delivered
Vibration returned to the acceptable band for this type of equipment and the pattern of repeated bearing and coupling failures stopped. The root cause was in the base, not in the components that had been replaced.
