Overview

A Salvage/Construction Demolition Diver dives and conducts underwater demolition for open ocean salvage, ship husbandry, and underwater construction operations. The diver applies precision demolition techniques to cut, flatten, or remove pilings, obsolete moorings, and other obstructions in channels, harbors, open oceans, and other areas of concern.

Core Skills

  • Precision removal of pilings and obsolete moorings
  • Underwater demolition for open ocean salvage

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

Underwater demolition supporting salvage, ship husbandry, and underwater construction transfers directly to commercial diving work in those settings.

How to prepare: Have a commercial diving employer assess your documented training and dive history against its assigned tasks, equipment, diving modes, and emergency procedures. OSHA requires relevant experience or training, CPR and first aid training, and diving physics and physiology training for personnel exposed to or controlling hyperbaric exposure; temporary impairments affecting safety preclude diving or hyperbaric exposure.

What the civilian work involves
  • Take appropriate safety precautions, such as monitoring dive lengths and depths and registering with authorities before diving expeditions begin.
  • Communicate with workers on the surface while underwater, using signal lines or telephones.
  • Obtain information about diving tasks and environmental conditions.
Civilian tools and software (examples)
  • Diving logbook software
  • Diving table software

Construction Blaster

Precision demolition of pilings, obsolete moorings, and underwater obstructions provides relevant demolition experience for construction blasting.

How to prepare: Ask a construction blasting employer to evaluate your documented experience against the competency evidence required for its blasting work and identify applicable state and local entry checks. OSHA requires explosives competency, knowledge of applicable laws, ability to understand and give orders, good physical condition, and no addiction to narcotics, intoxicants, or similar drugs.

What the civilian work involves
  • Examine blast areas to determine amounts and kinds of explosive charges needed and to ensure that safety laws are observed.

Notes & Sources

  • Military SCUBA qualification alone does not establish commercial diving task or mode competence, including surface-supplied experience.
  • ADCI is an industry certification framework, not a government license. Its Entry Level card accepts 625 documented hours of qualifying formal instruction or a recognized equivalent. Its Air Diver classification specifically requires 100 field days and 30 working dives, with only surface-supplied dives counting.
  • State blasting certification rules vary. New York, for example, requires three years of training and experience under a certified blaster before the written examination; this is not a nationwide eligibility rule.
  • Federal explosives business licenses and acquisition permits are distinct from employee authorization. License or permit holders must report newly authorized employee possessors to ATF, which conducts background checks as appropriate; employment does not itself require every worker to obtain an individual federal explosives business license.
