Process Safety & Incident Investigation
Tripod Beta Practitioner — Bronze Level: Developing Competent Investigators Through the Tripod Beta Methodology
A structured programme in the Tripod Beta methodology for incident investigation — building tripod trees, testing barriers, identifying preconditions and underlying causes, and producing recommendations that change the organisation rather than the individual.
Industry focus: Exploration & Production (Upstream Oil & Gas)
Who Should Attend
Designed for these roles
- HSE and process safety professionals leading investigations
- Operations, engineering and maintenance supervisors on investigation teams
- Incident investigators in upstream, petrochemical and marine operations
- Managers reviewing and approving investigation reports
Delivery formats
- Customised in-house training at your plant or office
- Public classroom delivery, subject to schedule
- Live online delivery where suitable
- Recommended group size: 8–20 participants
Problems Solved
What this course fixes
Investigations that conclude with human error and a retraining action
Barrier failures identified but preconditions never explored
Report quality varying widely between investigators
Recommendations that do not survive audit or repeat incident review
Learning Outcomes
What participants can do after the programme
Outcomes are written as tasks, not topics — so managers can verify capability back at work.
- Apply the Tripod Beta model of hazard, target, event and barriers
- Build a defensible tripod tree from evidence for a real incident
- Classify barrier failures and identify immediate causes, preconditions and underlying causes
- Plan and conduct investigation interviews and evidence gathering
- Produce recommendations addressed at organisational controls
Course Outline
Detailed programme content
Day 1 — Model & Framework
- Incident causation theory and the Tripod Beta model
- Hazard, target, event and the trio structure
- Evidence collection, timelines and interviewing
Day 2 — Tree Building
- Barrier identification, states and failure classification
- Immediate causes, preconditions and underlying causes
- Guided tree construction on a worked case
Day 3 — Practice & Assessment
- Team investigation on a full case pack
- Recommendation writing and management review
- Bronze level practice assessment and feedback
Practical Work
Practical exercises and case studies
Sessions are built around calculations, data interpretation and technical decisions. Case material is generic or anonymised — no client-confidential project data is used.
Building tripod trees from supplied incident case packs
Barrier identification and failure state classification exercises
Interview planning and evidence structuring practice
Bronze level practice assessment with individual feedback
Trainer Profile
Delivered by Sathish Kumar
Senior Trainer — Reliability, Maintenance & Rotating Equipment
19 years industry experience
Sathish builds maintenance strategies that survive contact with a real budget. His workshops use participants' own failure history, so teams leave with a revised task list rather than a certificate alone.
Real project exposure
- RCM implementation across critical pumps and compressors at a combined-cycle power plant
- Root cause failure analysis on repeat bearing failures in a boiler feed pump train
- Spare parts and criticality review for a palm oil refinery group
Certifications
- CMRP — Certified Maintenance & Reliability Professional
- Vibration Analyst Category III (ISO 18436-2)
- RCM2 Practitioner
Trainer allocation is confirmed in your proposal. Substitute trainers hold equivalent certification and sector experience.
