Comprehensive reliability analysis for multi-billion dollar fertilizer production facility spanning beneficiation, acid production, and granulation operations
Landmark greenfield phosphate mining complex representing one of the most integrated and technically advanced fertilizer production developments globally
Supporting Systems: Sulfuric Acid Plant • Power Generation • Electrical Substations • Utilities Distribution
The RAM study covered the full production chain, incorporating more than 1,600 major equipment items into a detailed reliability model. Advanced simulation and failure data analysis quantified expected plant availability performance across all process areas, with results ranging between 87% and 99% depending on design intent and operational criteria.
Systematic approach combining probabilistic modeling, failure data analysis, and Monte Carlo simulation
Created comprehensive system reliability models representing equipment interdependencies, redundancy configurations, and failure propagation paths. Each major production area was modeled with detailed logic capturing series, parallel, standby, and load-sharing configurations across 1,600+ equipment items.
Executed 100+ Monte Carlo iterations to capture stochastic behavior of equipment failures and repairs. This probabilistic approach accounts for variability in failure distributions, maintenance durations, and operational scenarios; producing statistically robust availability predictions with defined confidence intervals rather than deterministic point estimates.
Equipment failure and repair characteristics were modeled using appropriate statistical distributions (Weibull, exponential, lognormal) fitted to industry-standard reliability databases and OEM specifications. Mean Time Between Failures (MTBF) and Mean Time To Repair (MTTR) parameters were validated against similar operating environments and adjusted for application-specific conditions including environmental factors, operating severity, and maintenance practices.
Performed systematic sensitivity studies varying key parameters (failure rates, repair times, redundancy configurations) to quantify their impact on system availability. Multiple operational scenarios were evaluated including normal operations, planned maintenance shutdowns, and degraded mode operations to ensure robustness across the full operational envelope.
