  • Underwater project material and manpower estimation
  • Recompression chamber operations supervision
  • Command-designated diving and demolition supervision

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

Military air-diving experience, underwater construction and repair work, and diving-project supervision directly support commercial diving assignments.

How to prepare: Have a commercial diving employer assess your existing Navy training records and dive logs against the proposed assignments and OSHA dive-team requirements before selecting additional training. If seeking ADCI classification, request an assessment against its Entry Level requirement of 625 documented formal-instruction hours or a recognized equivalent, or its Air Diver requirements of 100 field days and 30 working dives, with only surface-supplied dives counting.

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.
  • Obtain information about diving tasks and environmental conditions.
Civilian tools and software (examples)
  • Diving logbook software
  • Diving table software

Notes & Sources

  • For work covered by OSHA's commercial diving standard, dive-team members need task-specific experience or training and CPR and first-aid training; those exposed to or controlling hyperbaric exposure also need diving-related physics and physiology training.
  • OSHA prohibits diving or other hyperbaric exposure during a known temporary physical impairment or condition likely to adversely affect the dive-team member's safety or health.
