Definition(s)
Diving project
A ‘diving project’ is the term used for the overall diving job whether it lasts two hours or two months. Diving project can apply to both a continuous period of elevated pressure, as in saturation diving, and to a number of diving operations, possibly taking place over several days, where the divers are not under continuous elevated pressure. The diving project does not necessarily finish once the last diver has returned to atmospheric pressure. Most decompression procedures require the diver to remain in the close vicinity of a recompression chamber for a specified time in case there is a need for treatment of symptoms of decompression illness. The diving project is only completed once that time period has expired.

“Diving project” means any activity, made up of one or more diving operations, in which at least one person takes part or will take part as a diver and extends from the time when that person, or the first such person, commences to prepare to dive until that person, or the last such person, has left the water, chamber or other environment in which the dive, or any part of the dive, took place and has completed any requisite decompression procedures, including, where it may be reasonably anticipated that this will be needed, any therapeutic recompression.

Definition(s)
Diving operation
“Diving operation” means any work or activity that is associated with a dive and that takes place during the total dive time and includes- any work or activity involving a diver or pilot,
- the activities of a person assisting a diver or pilot involved in the dive, and
- any use of an ADS in the dive (opérations de plongée).
Diving operation
Diving operations can be made up of either a number of dives or even a single dive. A diving operation is the portion of a diving project identified in the diving project plan which can be supervised safely by one person. It will normally be evident what this portion of work is, but factors such as the task, site conditions and the diving techniques to be used, all contribute to making the decision. For example, a 28-day diving project may be made up of 40 diving operations.
