Reliability Engineering: RCM, Root Cause Analysis, Weibull
The reliability engineer's toolkit for plants, utilities and oil and gas: failure rate, MTBF and availability, failure patterns and the P-F curve, criticality, equipment FMECA, the seven questions of reliability-centred maintenance with task selection and failure-finding intervals, root cause analysis with 5 Whys, fishbones, logic trees and fault trees, Weibull analysis by hand and in Python, block diagrams, spares, bad actors, precision maintenance and KPIs.
Free to learn. Verifiable certificate £19 when you pass the final exam (optional, VAT included).

Outcome
What you will be able to do
Calculate MTBF, failure rate, reliability and availability from plant records; explain the six failure patterns and set inspection intervals from the P-F interval; rank assets by criticality; write an equipment FMECA; run an RCM analysis through the seven questions, choose tasks and default actions and calculate failure-finding intervals; lead a root cause analysis with 5 Whys, a fishbone, a logic tree and a fault tree; fit Weibull distributions with suspensions by hand and in Python and turn them into replacement and spares decisions; calculate system reliability from block diagrams; size spares with the Poisson model; find bad actors; and track a reliability programme with leading and lagging KPIs.
- Calculate MTBF, MTTR, failure rate, reliability and availability from plant failure records
- Explain the six failure patterns and set on-condition intervals from the P-F interval
- Rank assets by criticality and write an equipment FMECA with severity read first
- Run an RCM analysis through the seven questions and choose tasks and default actions
- Calculate failure-finding intervals for protective devices from MTBF and tolerable unavailability
- Lead a root cause analysis with 5 Whys, a fishbone, a logic tree and a fault tree
- Fit Weibull distributions with suspensions by hand and in Python and pick a replacement age
- Size spares with the Poisson model, find bad actors and track leading and lagging KPIs
Software
A spreadsheet (LibreOffice Calc is free) for the maths, the FMECA and the RCM worksheets. Python 3 with the free reliability and SciPy libraries for Weibull analysis (Google Colab runs it in a browser with nothing to install). Commercial RCM and life data tools are shown in some lessons but are not needed.
Hardware
None. Any laptop with a browser is enough.
