The Short Definition
A commercial diver is a tradesperson who works underwater to inspect, build, repair, or recover things. That's it. You are not a scientist studying coral reefs. You are not a photographer capturing underwater scenery. You are a laborer and a technician who happens to work while submerged, usually in water that is dark, cold, and moving. The things you work on are the things society needs to function: bridges, dams, ship hulls, oil rigs, pipelines, water intakes, sewage outfalls, and the cables that carry power and internet across the seafloor.
The two main branches of the work are inland and offshore. Inland divers work in lakes, rivers, quarries, and harbors — often on infrastructure like docks and dams. Offshore divers work in the ocean, usually supporting oil and gas production or offshore wind farms. The skill set overlaps, but the lifestyle is different. Inland divers often go home at night.
