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

  1. Walk me through your background + operational experience.

    What it tests: Story arc - training + operational career + safety + integrity exposure.

  2. Tell me about an operational role or project you've held.

    What it tests: Operational rigor + safety + cross-team coordination.

  3. Why oil + gas midstream vs other energy paths?

    What it tests: Authentic alignment - operational scale, safety + integrity discipline, infrastructure permanence.

  4. Why this asset type - liquids pipeline / gas transmission / terminal / LNG?

    What it tests: Specificity. Generic answers fail.

  5. Why this firm?

    What it tests: Real homework - assets + ops + safety - not name-drop.

  6. What's your read on our asset portfolio + recent ops events?

    What it tests: Industry literacy - asset footprint, products, recent events.

  7. Tell me what you understand about our safety + integrity posture.

    What it tests: Safety + IMP fluency on this firm's record.

  8. 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
