Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Transportation, Storage, and Distribution Managers

Supervising petroleum receipt, storage, testing, distribution, and equipment maintenance transfers directly to fuel terminal and bulk distribution operations.

How to prepare: Build a civilian work sample showing how you would plan terminal storage capacity, product testing, equipment maintenance, and distribution schedules.

What the civilian work involves
  • Supervise the activities of workers engaged in receiving, storing, testing, and shipping products or materials.
  • Inspect physical conditions of warehouses, vehicle fleets, or equipment and order testing, maintenance, repairs, or replacements.
  • Collaborate with other departments to integrate logistics with business systems or processes, such as customer sales, order management, accounting, or shipping.
Civilian tools and software (examples)
  • Microsoft Excel
  • Microsoft Project

Petroleum Pump System Operators, Refinery Operators, and Gaugers

Oversight of petroleum pipelines, hose lines, terminals, dispensing systems, and user maintenance provides directly relevant experience for pipeline and terminal operator work.

How to prepare: Practice interpreting pipeline flow, pressure, and alarm information through introductory SCADA training, focusing your search on terminal and pipeline openings rather than refinery process roles.

What the civilian work involves
  • Signal other workers by telephone or radio to operate pumps, open and close valves, and check temperatures.
  • Monitor process indicators, instruments, gauges, and meters to detect and report any possible problems.
  • Start pumps and open valves or use automated equipment to regulate the flow of oil in pipelines and into and out of tanks.
Civilian tools and software (examples)
  • Inventory tracking software
  • Supervisory control and data acquisition SCADA software

Quality Control Systems Managers

Supervising petroleum laboratories, evaluating physical and chemical test results, and recommending disposition of off-specification products transfers to petroleum quality control management.

How to prepare: Prepare a sample petroleum quality review that links test results to product specifications, disposition recommendations, and procedure updates.

What the civilian work involves
  • Review and update standard operating procedures or quality assurance manuals.
  • Monitor performance of quality control systems to ensure effectiveness and efficiency.
  • Analyze quality control test results and provide feedback and interpretation to production management or staff.
Civilian tools and software (examples)
  • Microsoft Excel
  • Adobe Acrobat
