What is commercial diving?

Commercial diving considered an application of professional diving where the diver engages in underwater work for industrial, construction, engineering, maintenance or other commercial purposes which are similar to work done out of the water and where the Diving is usually secondary to the work. 

A Commercial diver is the most common type of professional diver that works for pay. There are a number of different types of commercial dives but the most is the offshore diver working in the oil and gas industry. Commercial divers are extremely skilled professionals. They often work in dangerous circumstances and require the proper training and certification necessary to meet regulation of the local authority. The procedures are often regulated by legislation and codes of practice as it is a inherently hazardous occupation and the the diver work as a member of a team.

Is Commercial diving dangerous?

Yes Commercial diving is a dangerous maritime job. Diving carries inherent risks, no matter what job is being done or the conditions in the water. Divers can suffer from a number of condition and symptoms related to pressure and gases. These include gas narcosis, which can occur on especially on deep diving, gas toxicity from oxygen and carbon dioxide, decompression sickness, which occurs sometimes ascending, pain from expanding gas in the blood or lugs. Besides this have a lot different work related injuries.

Saturation diving is diving for periods long enough to bring all tissues into equilibrium with the partial pressures of the inert components of the breathing gas. It is a diving technique that allows divers to reduce the risk of decompression sickness ("the bends") when they work at great depths for long periods of time because once saturated, decompression time does not increase with further exposure.^[1][2] Saturation divers typically breathe a helium–oxygen mixture to prevent nitrogen narcosis, but at shallow depths saturation diving has been done on nitrox mixtures.

In saturation diving, the divers live in a pressurized environment for long periods up to 28 days, which can be a saturation system on the surface, or an ambient pressure underwater habitat when not in the water. Transfer to and from the pressurized surface living quarters( sleeping, eating, waking up and again sleep) to the equivalent depth is done in a closed, pressurized diving bell. This may be maintained for up to several weeks, and they are decompressed to surface pressure only once, at the end of their tour of duty. By limiting the number of decompressions in this way, the risk of decompression sickness is significantly reduced, and the time spent decompressing is minimized. Thats why saturation diving is the second home of commercial diver underwater
