📐 Key Calculations

Splice Fatigue Life

N = C × (Δσ)^−m
Result: 1.8M cycles
Validated 3× life extension over legacy splices

Tension Variation Allowance

ΔT/T_nom ≤ 5%
Result: 4.2%
Prevented edge wear and mistracking

📊 Results

Failures reduced to 3/yr; $2.1M annual demurrage savings; OEE increased from 78% to 92%

💡 Lessons Learned

  • Real-time tension feedback is non-negotiable for long conveyors
  • Splice inspection must include thermal imaging at full load
