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.

Mechanical Door Repairers

Removing, installing, testing, and replacing shipboard watertight closures and their components transfers directly to mechanical door repair.

How to prepare: Seek supervised hands-on training in commercial door spring systems and electric openers to extend your closure maintenance experience.

What the civilian work involves
  • Adjust doors to open or close with the correct amount of effort, or make simple adjustments to electric openers.
  • Repair or replace worn or broken door parts, using hand tools.

Maintenance Workers, Machinery

Watertight closure component removal, replacement, and reassembly provides a mechanical maintenance foundation for machinery repair work.

How to prepare: Take a practical machinery maintenance course covering equipment dismantling, parts replacement, and reassembly beyond door and hatch mechanisms.

What the civilian work involves
  • Dismantle machines and remove parts for repair, using hand tools, chain falls, jacks, cranes, or hoists.
  • Reassemble machines after the completion of repair or maintenance work.
  • Install, replace, or change machine parts and attachments, according to production specifications.
Civilian tools and software (examples)
