Commercial Diving

The primary distinction between professional and recreational diving is that the recreational diver is responsible primarily for his/her own actions and safety but may voluntarily accept limited responsibility for dive buddies, whereas the professional diver is part of a team of people with extensive responsibilities and obligations to each other and usually to an employer or client, and these responsibilities and obligations are formally defined in legislation, regulations, operations manuals, standing orders and compulsory or voluntary codes of practice.

In many cases a statutory national occupational health and safety legislation constrains their activities.

Commercial offshore diving, sometimes shortened to just offshore diving, is a branch of commercial diving, with divers working in support of the exploration and production sector of the oil and gas industry in places such as the Gulf of Mexico in the United States, the North Sea in the United Kingdom and Norway, and along the coast of Brazil. The work in this area of the industry includes maintenance of oil platforms and the building of underwater structures.
Equipment used for offshore diving tends to be surface supplied equipment but this does vary depending on the nature of the work and location. For instance Gulf of Mexico based divers may use wetsuits whilst North Sea divers need drysuits or even hot water suits due to the temperature of the water.
