Commercial Diving: courses, careers, and where to study

Commercial Diving trains you to work underwater as a professional diver, learning surface-supplied and scuba diving, dive physics, and underwater construction, inspection, and salvage skills.

Commercial Diving prepares you to perform skilled work beneath the surface, using both scuba and surface-supplied air systems to reach and operate at depth. Coursework covers diving physics and physiology, gas laws, decompression theory and the use of decompression and recompression chambers, and dive planning that keeps a team within safe time and depth limits. You train with helmets, masks, umbilicals, communication systems, and life-support equipment, and you practice tasks such as underwater welding and cutting, rigging and lifting, inspection and nondestructive testing, salvage, and the installation, repair, or demolition of submerged structures and pipelines. Where Marine Technology focuses on operating vessels, sensors, and instruments to support ocean research and survey, this field focuses on putting the diver in the water to build, inspect, and maintain underwater systems by hand.

Most students complete a diploma or certificate program at a commercial diving school and log supervised dives across the methods and tasks they will face on the job, and many programs prepare graduates for credentials recognized by industry bodies such as the Association of Diving Contractors International. Graduates work in offshore oil and gas, marine construction and infrastructure, ship husbandry and underwater ship repair, inland and harbor projects, and underwater inspection and salvage, with some moving toward dive supervisor, saturation diving, or nondestructive testing roles over time. A program is preparation, not a guaranteed job: this is physically demanding, safety-critical work, and pay, project availability, and demand vary by employer, region, season, and experience, with offshore and saturation work carrying different requirements and conditions than inland diving.

In federal data for the closely related occupation of commercial divers, the U.S. Bureau of Labor Statistics reports a 2024 median wage of $61,130 and projects employment to grow about 8.5% from 2024 to 2034; a postsecondary nondegree award is the typical entry-level education for that occupation. National figures are occupation-wide medians across all experience levels, not starting wages or graduate outcomes.
