Pipeline Operations interview prep.
Pipeline operators, control room operators, integrity engineers, terminal + storage operators, LNG ops.
What interviewers look for
- Can the candidate operate safely + within regulatory framework (PHMSA + DOT + EPA)?
- Do they understand pipeline integrity management - HCAs, ILI, ECDA, direct assessment?
- Are they fluent in control room ops + SCADA + leak detection + abnormal operations response?
- Can they manage maintenance + reliability + integrity in 24/7 + multi-shift environment?
- Do they navigate terminal + storage + LNG operational + safety discipline (CFR 193, NFPA 59A)?
- Are they prepared for emergency response + spill management + agency engagement?
- Long-game fit - operator / lead / supervisor / superintendent / regional manager trajectory?
Behavioural questions to expect
Walk me through your background + operational experience.
What it tests: Story arc - training + operational career + safety + integrity exposure.
Tell me about an operational role or project you've held.
What it tests: Operational rigor + safety + cross-team coordination.
Why oil + gas midstream vs other energy paths?
What it tests: Authentic alignment - operational scale, safety + integrity discipline, infrastructure permanence.
Why this asset type - liquids pipeline / gas transmission / terminal / LNG?
What it tests: Specificity. Generic answers fail.
Why this firm?
What it tests: Real homework - assets + ops + safety - not name-drop.
What's your read on our asset portfolio + recent ops events?
What it tests: Industry literacy - asset footprint, products, recent events.
Tell me what you understand about our safety + integrity posture.
What it tests: Safety + IMP fluency on this firm's record.
Walk me through an abnormal operation or incident response.
What it tests: Operational + emergency response fluency - decision-making under pressure, regulatory reporting.
Technical concepts to master
Pipeline operations + control room
- SCADA
- Supervisory Control + Data Acquisition - real-time monitoring + control system for pipeline operations.
- Leak detection
- Methods to detect leaks - computational (CPM mass balance), pressure transient, fiber-optic, ROW patrol, public + aerial.
- CRM (Control Room Management)
- PHMSA-mandated framework covering control room operations - staffing, training, alarm management, fatigue, MOC.
- Abnormal Operating Conditions (AOC)
- Operations outside normal parameters - low / high pressure, unscheduled shutdown, leak indication.
Integrity Management Program (IMP)
- HCA (High Consequence Area)
- Areas defined by PHMSA where pipeline release could have significant impact - populated, water, environmental.
- Threat assessment + 9 threats
- Standard pipeline threats - external corrosion, internal corrosion, SCC, mechanical damage, weather + outside force, etc.
- Reassessment cadence
- PHMSA-required reassessment interval based on threat + integrity findings - typically 5 / 7 years.
- MAOP verification + record validation
- Documenting + verifying Maximum Allowable Operating Pressure with traceable, verifiable, complete records.
Terminal + LNG ops + safety
- Terminal operations
- Receipt, storage, custody transfer, delivery of liquids - includes tank farm + truck / rail / marine loading.
- Vapor recovery + emissions
- Capture + treatment of hydrocarbon vapors from loading / storage - EPA + state requirements.
- LNG plant operations
- Liquefaction + storage + send-out + truck / ship loading at LNG plants - requires cryogenic + thermal management.
- Custody transfer + measurement
- Accurate measurement of product transferring custody - API MPMS + state regs.
Emergency response + spill management
- Facility Response Plan (FRP) / Emergency Response Plan
- Required plan covering spill response + emergency procedures + contractor / equipment / training.
- Incident Command System (ICS)
- Standard response organisation - command, ops, planning, logistics, finance + admin.
- Spill containment + recovery
- Booms, skimmers, vacuum trucks, in-situ burn, dispersants - tactical spill response tools.
- Regulatory notification + reporting
- Immediate notification to NRC + PHMSA + state + community per release thresholds + timing.
Practical drills
- SCADA shows a 10% pressure drop on a transmission line with no scheduled maintenance. Leak detection algorithm hasn't triggered alarm. Walk through your response.
- Recent ILI run identified 22% wall loss on a 30-year-old transmission line in HCA segment. Walk through your response.
- A landowner reports a sheen on a creek crossed by your liquids pipeline. Walk through your immediate + 48-hour response.
Smart-question anchors
- Asset portfolio - pipeline + terminal + LNG mix + product type
- Safety record + integrity program - PHMSA enforcement, ILI cadence, HCA coverage
- Recent capital + integrity investment - replacements, recoating, SCADA + leak detection upgrades
- Control room + CRM maturity - SCADA generation, leak detection sensitivity
- Regulatory engagement - PHMSA + DOT + FERC + EPA + state
