How Shell Ind Pvt Ltd Built a Zero-Error Drum Loading & Traceability System
Manual drum handling in oil and lubricant manufacturing can cause costly errors and contamination risks. For Shell India Pvt Ltd, we developed an on-premises QR/Barcode-based drum verification system that validates materials before unloading, ensuring traceable, error-proof operations with complete audit visibility across operators, supervisors, and material movements.
Problem Statement
In oil and lubricant manufacturing, material accuracy is critical. Every drum used in production must match the correct production order, batch requirement, and process stage. Before implementation, Shell Ind Pvt Ltd relied heavily on manual drum identification and operator-level checks during drum unloading. This created a high-risk environment where even a small human error could result in wrong oil or additive usage. The key business risks included: High possibility of wrong drum or wrong additive usage. Potential batch contamination due to incorrect material unloading. Costly rework and production loss if an error was detected late. Audit gaps due to limited traceability of who handled which drum and when. Dependency on manual supervision for process control. The objective was simple: prevent the error before it happens, not after the batch is impacted.
Our Approach
The drum handling process was studied from assignment to unloading. The focus was not only on digitising the process, but on creating a practical shop-floor control system that operators and supervisors could use easily. The solution was designed around three principles: First, every drum must have a unique digital identity through QR or barcode scanning. Second, the unloading task must be assigned and controlled by a supervisor to ensure accountability. Third, the system must automatically block incorrect unloading attempts instead of only recording them later. This approach helped convert a manual, people-dependent process into a controlled, system-verified workflow.
The Solution
An on-premises QR/Barcode drum verification system was implemented where every drum is uniquely identified and tracked before unloading.
Supervisors assign drum unloading tasks to operators through the system. This ensures clear ownership and prevents unplanned or unauthorised drum movement.
Before unloading, the operator scans the QR or barcode on the drum. The system validates the scanned drum against the assigned production order.
If the drum is correct, the operator is allowed to proceed with unloading. If the drum does not match the production order, the system automatically blocks the unloading process.
Every scan, validation, approval, rejection, and operator action is captured in a complete audit trail, giving the business full traceability for compliance, investigations, and quality review.
The Pilot
The supervisor assigns the drum unloading task to the operator. The operator scans the QR/Barcode on the drum before unloading. The system checks the drum against the production order. If the drum is correct, unloading is allowed. If the drum is incorrect, the system blocks the unloading process. All actions are recorded with user, time, drum, and production order traceability. This ensures that quality control happens at the point of execution, not after production damage has already occurred.
Pilot Results & Optimisations
Shell Ind Pvt Ltd moved from a manual verification process to a controlled, traceable, and system-driven drum unloading workflow. The solution delivered: Zero wrong drum unloading incidents. Reduced risk of batch contamination. Lower possibility of costly rework. Complete audit trail for every unloading activity. Improved supervisor visibility and operator accountability. Better compliance readiness. Stronger quality consistency across production. The system also created a foundation for future digital traceability across lubricant blending, base oil handling, additive management, grease manufacturing, and bulk storage operations.
Results
The system helped Shell Ind Pvt Ltd significantly reduce operational risk in the drum handling process. The most important outcome was the elimination of wrong drum unloading incidents after implementation. By blocking incorrect drums before unloading, the business avoided potential batch contamination, rework, and material loss. The estimated cost of a single wrong drum incident was in the range of ₹13–22 Lakhs. With the system in place, the expected annual loss avoided was estimated at ₹25–40 Lakhs, with an investment range of ₹15–25 Lakhs and an expected payback period of less than 12 months. Beyond direct financial savings, the system also improved quality consistency, operator accountability, supervisor control, audit readiness, and shop-floor confidence.
Conclusion
Shell Ind Pvt Ltd did not just digitise a manual process. They built a mistake-proof operational control layer for one of the most critical points in their production workflow. By verifying every drum before unloading and automatically blocking incorrect actions, the system helped prevent costly errors before they could affect product quality. The project demonstrated a simple but powerful idea: in manufacturing, the best automation is not only about speed. It is about control, traceability, and preventing the mistake before it reaches production.
