A refinery turnaround is the most capital-intensive event on the calendar — and delays can cost upwards of $1 million per day in lost production (API, cited via AMACS 2025). Most organisations don’t lose that time in execution. They lose it in planning: fragmented spreadsheets, a scheduling tool that doesn’t talk to the ERP, and reporting that’s already stale by the time it reaches leadership.
This white paper, co-authored by Nayara Energy and Maventic Innovative Solutions, examines that gap — and documents how Nayara closed it at the Vadinar refinery, India’s second-largest single-site facility, running a 20 MMTPA operation with 16,000+ activities per turnaround cycle.
What’s inside:
- A four-stage STO Planning Maturity Framework (Reactive → Structured → Integrated → Predictive) to benchmark your own programme
- Why the P6–SAP disconnect is the central, most under-addressed planning problem in large-scale STO
- Nayara Energy’s before-and-after: from multi-file Excel reconciliation to a live, connected planning architecture
- Five concrete recommendations for plant and IT leadership evaluating a similar transition
“Your commitment to continuously enhancing the Procify STO Manager software… helped ensure smooth execution of key turnaround activities.”
