Rehabilitation of hydropower turbines and components
Restore generating unit availability and reliability through a technically defined rehabilitation strategy.
Braz Hydro structures interventions for turbines, runners, distributors, spiral cases, shafts and other hydromechanical components. The scope is defined from the equipment’s actual condition, unit requirements and existing interfaces.
When rehabilitation is needed
Components worn, corroded or damaged after years of operation.
Difficulty maintaining legacy equipment without complete documentation.
Recurring outages, operating restrictions or the need to extend service life.
Rehabilitation stages
Unit inspection
We assess components, interfaces, foundations, auxiliary systems and available documentation.
Scope definition
We prioritize repairs, replacements, modifications and commissioning activities according to project risks and objectives.
Engineering and execution
We develop the solution, support manufacturing or repair and coordinate installation requirements.
Testing and delivery
We support final inspections, functional checks, testing and commissioning within the contracted scope.

What we need
- Plant, generating unit and turbine data.
- Drawings, manuals, reports and maintenance history.
- Preliminary scope, outage constraints and site access conditions.
- Failure, inspection, vibration and performance records.
What you receive
- A rehabilitation scope based on the equipment’s actual condition.
- Engineering, manufacturing, repair or replacement documentation.
- An applicable inspection, testing and commissioning plan.
- Recommendations for maintenance and operation after the intervention.
Frequently asked questions
Can rehabilitation be performed at PCH and CGH facilities?
Yes. The scope can be adapted to PCH, CGH and other hydropower units, considering their size, interfaces and available data.
Can you work with incomplete documentation?
Yes. Reverse engineering, field measurements and component inspection can help reconstruct the information required.
Does Braz Hydro support commissioning?
Commissioning support can be included according to the technical scope, agreed responsibilities and planned tests.
