Many occupational groups with a great diversity of functions have been and are necessary for producing oil and gas from the field. Articles under the organisation and occupations heading provide a somewhat simplified overview of most of the professions involved on Ekofisk from 1971 to 1998.
As technologies have changed, some of these disciplines have disappeared or been transferred to land.
A mix of text, photographs, films and interviews allows people who have never been offshore to form a picture of life out there and of the people behind the job descriptions.
The field passed through several organisational phases until the major Ekofisk II redevelopment project became operational in 1998.
These include times when new platforms were brought on stream and the organisation was characterised by growth. In other periods, low oil prices and major investments demanded efficiency improvements.
Interviews with some key players in the administration on land illuminate the background for these changes.
