Health 76/100 and age 15 yrs do not justify capex
Replace component21
No single failing component identified
Repair now12
Low downtime cost, but unplanned mobilisation
Scenario comparison
OPTION A
Repair immediately
Stop line now, replace component using emergency transfer
Failure risk2%
Expected costRp 98 m
Planned downtime4 h
Lowest risk, but takes the unit out of evacuation/field work immediately.
Recommended
OPTION B
Repair in low-production window
Replace at next planned shutdown
Failure risk10%
Expected costRp 67 m
Planned downtime4 h
Recommended — balances failure risk against production loss at the next planned shutdown.
OPTION C
Continue monitoring
Run to next scheduled shutdown (14 days)
Failure risk29%
Expected costRp 77 m
Planned downtime0 h
Expected cost dominated by probability-weighted unplanned outage.
Recommendation: Schedule maintenance
Confidence80%Replace hydraulic filter; sample oil. Option B expected cost Rp 67 m vs Rp 77 m if left to run; residual risk 10%.
