Key Facts & Information
|Overview||Thousands of structures, like bridge supports, ocean oil rigs, and marine research equipment lie underwater and it is the job of commercial divers to maintain those structures. Using scuba gear, commercial divers do a wide variety of underwater tasks, including installing equipment and structures, conducting tests or experiments, rigging explosives, and photographing structures or marine life.|
|Key Requirements||A fondness for physical activity and adventure, and the ability to stay calm and collected in stressful conditions|
|Minimum Degree||Vocational or Associate's degree|
|Subjects to Study in High School||Physics, algebra; if available, marine biology|
|Projected Job Growth (2014-2024)||Much Faster than Average (21% or more) In Demand!|
Training, Other Qualifications
Commercial divers typically need a high school diploma or GED. Training and certification through a commercial diving school is mandatory for most jobs. Basic scuba diving certification should be obtained prior to attending a commercial diving program.
Because there are a large variety of jobs to be done underwater, commercial divers may also need to acquire other skills, like underwater welding, photography, or construction, depending on the type of work they'll be doing. In some companies, on-the-job training by more experienced divers also occurs.
Education and Training
A high school diploma or GED and certification through a commercial diving school are necessary for most commercial diving jobs.
Frequent scuba diving is physically taxing and commercial divers must be extremely fit. Good mental health is also critical because commercial divers, such as search and rescue workers, often work in emotionally taxing environments. The smallest deviation from diving protocols can have disastrous consequences, so divers must be detail oriented and able to remain calm under stress.
Nature of the Work
Commercial divers perform underwater activities related to construction, salvage, repair, research, rescue and photography. They use specialized scuba equipment. The exact type of equipment depends on the diving conditions, but may include wet suits, dry suits, hot-water-heated suits, diving bells, decompression chambers, full face masks and air compressors.
Commercial divers find employment with many types of companies and organizations. Oil companies, demolition companies, police and fire departments, underwater salvage companies, and the Navy are just a few of the places where commercial divers work. Depending on the task, commercial divers may need other skills, such as welding, rigging explosives, photography, or emergency management.
Commercial divers spend their working hours in wet suits and scuba gear, swimming around in a variety of bodies of water, from freezing oceans to murky lakes. They are found in swamps, streams, rivers, lakes, oceans, ports, harbors, locks, weirs, reservoirs, spillways, quarries, pools, and sewers.
On the Job
