When Divers are not diving they will be required to carry out other duties to support operations. Working days can be long and can be based in some of the harshest subsea environmental conditions in the North Sea or abroad. Safety is of paramount importance due to the considerable risks associated with diving operations.

In the industry

Divers are responsible for carrying out subsea work and communicating with top side engineering teams with regards to the condition of subsea structures, equipment and materials so that repairs can be planned in to the work schedule. Divers support subsea projects and activities offshore, and can work for a range of companies including companies who own or manage production facilities (known as Operators), major Subsea contractors, Service Companies and Engineering Consultancies. They fulfil a key role in enabling oil and gas to be produced and extracted safely from subsea production facilities.
