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.

Commercial Divers

Air and mixed-gas diving, diving equipment repair, underwater inspections, ship repair, and salvage provide directly transferable experience for commercial diving work.

How to prepare: Compile your dive logs and equipment repair records for review with a commercial diving employer to identify gaps between your documented experience and its diving operations.

What the civilian work involves
  • Take appropriate safety precautions, such as monitoring dive lengths and depths and registering with authorities before diving expeditions begin.
  • Check and maintain diving equipment, such as helmets, masks, air tanks, harnesses, or gauges.
  • Communicate with workers on the surface while underwater, using signal lines or telephones.
Civilian tools and software (examples)
  • Diving logbook software
  • Diving table software
