Refurbishment of Rotor EX.212-C-51 (Induced Draft Fan)

PT Pertamina RU II Dumai is a major oil refinery unit in Indonesia, responsible for processing crude oil into a wide range of essential petroleum products. To sustain continuous operations, the facility depends on various critical rotating equipment, including fans and compressors that support plant reliability and efficiency.

In 2024, Rotor EX.212-C-51, including its draft fan, experienced performance degradation due to long-term operation under high thermal and mechanical stress. PT Pertamina RU II Dumai entrusted Taka Turbo’s Workshop Repair team to execute a full refurbishment project, restoring the rotor’s functionality and ensuring operational reliability.

The Challenge

The project posed several critical challenges:

Rotor Wear and Degradation
Prolonged exposure to demanding refinery conditions led to material fatigue and imbalance.

Draft Fan Reliability Issues
Deterioration risked reduced efficiency in air handling and process stability.

Precision Demands
The rotor required high-accuracy machining and balancing to meet refinery performance standards.

Strict Turnaround Schedule
Repairs needed to be completed within the refinery’s maintenance window to prevent production delays.

Our Solution

Taka Turbo carried out a comprehensive workshop refurbishment program, involving:

Initial Inspection & Non-Destructive Testing (NDT)
Detailed assessment to identify cracks, wear, and material integrity.

Rotor Repair & Machining
Precision welding and machining techniques to restore worn-out surfaces and correct dimensional accuracy.

Dynamic Balancing
High-precision rotor balancing to ensure vibration-free operation.

Draft Fan Refurbishment
Reconditioning of the fan blades and shaft to restore airflow efficiency and structural strength.

Quality Assurance & Final Testing
Multi-stage inspections and performance checks to validate compliance with refinery operational standards.

The Result

Rotor Performance Restored
The refurbished rotor met OEM-equivalent performance levels.

Improved Operational Stability
Vibration levels significantly reduced, ensuring smoother operation.

Draft Fan Reliability Secured
Enhanced airflow efficiency supported refinery process stability.

On-Time Completion
Project delivered within the planned maintenance schedule, preventing costly downtime.

Business Impact

The refurbishment of Rotor EX.212-C-51 and Draft Fan reinforced the reliability of PT Pertamina RU II Dumai’s refining operations. By extending the lifespan of critical assets, the client avoided costly replacement, minimized downtime risk, and sustained operational efficiency.

For Taka Turbo, this project highlights our capability in workshop-based rotor and fan refurbishment, proving our ability to deliver precision engineering solutions that meet the stringent demands of the oil and gas industry.
