When oil and gas was discovered in the North Sea, the need for a meeting place for the companies in this new industry emerged. ONS was held for the first time in 1974, and has more than 40 years of proud history. ONS is a non-profit foundation, and was established by Stavanger City Council, Statoil, Stavanger Forum and the Norwegian Petroleum Society. ONS has developed with the times – as has the name. In the seventies, ONS was short for Offshore North Sea, as the event was targeted at companies with business in the North Sea basin. However, the oil industry soon started to explore other parts of the Norwegian Continental Shelf. The ONS event grew alongside the industry, more exhibitors and visitors participated and the conference topics became broader. So the name was changed to Offshore Northern Seas. Today, the event attracts visitors from all over the world, and is known just as ONS.
