MRPL Mangalore Refinary
Robotic Diagnosis & Restoration of Blocked OWS & SWS Networks Using Bandicoot
PROJECT BACKGROUND
In 2021, MRPL encountered a critical issue unexplained overflow in multiple OWS and SWS manholes. Despite using conventional methods like manual scavenging, jetting, and super-suction vehicles, the refinery team was unable to identify or resolve the root cause of the obstruction.
To address this, Genrobotics was brought in for a pilot diagnostic deployment using the Bandicoot robot.
2021 DEPLOYMENT – DIAGNOSTIC PHASE
SCOPE
- 50 manholes selected for robotic inspection and cleaning.
ACTION TAKEN
- All manholes cleaned using the Bandicoot robot.
- High-pressure jetting deployed to clear internal line blockages.
OUTCOME
- Root cause identified through robotic visual inspection.
- Obstructions removed.
- Entire OWS & SWS line restored to full operational flow within 30 days.
2025 - PHASE 2 DEPLOYMENT
Encouraged by the proven success in 2021, MRPL re-engaged Genrobotics in 2025 for a second plant experiencing similar overflow issues. Using the same integrated robotic + jetting approach, the problem was diagnosed and fully resolved again - validating repeatability and scalability of the robotic intervention model.
CHALLENGES ADDRESSED
- Unknown internal blockages in critical treatment lines.
- Failed conventional methods.
- Overflow creating compliance and safety risks.
- Limited shutdown windows for rectification.
SOLUTIONS DELIVERED
- Pinpointed Blockages: Bandicoot's camera system enabled accurate fault detection.
- Fast Clearance: Robotic scooping + jetting resolved obstructions quickly.
- No Human Entry: Full remote operation ensured zero worker risk.
- 30-Day Turnaround: Complete restoration within operational deadlines.
OUTCOMES & BENEFITS
- Prevented environmental hazards due to overflow.
- Brought critical systems back online without excavation.
- Built MRPL's confidence in robotic maintenance strategy.
- Demonstrated superior ROI over traditional cleaning methods.
