It operates primarily to oil platforms on the Norwegian continental shelf in the North Sea and the Norwegian Sea, with crew change, infield shuttle and search and rescue operations.

Though the global headquarters are in Richmond, B.C., Canada, the company has its main base at Stavanger Airport, Sola.

But in 1966 the first steps in the Norwegian oil exploration started, and the company acquired two Sikorsky S-61 helicopters and at the same time changed its name to Helikopter Service.

In 1993 it also started operating the Eurocopter AS365 Dauphin with possibilities for search and rescue purposes.

In 2000 the company sold the subsidiaries Lufttransport to Norwegian Air Shuttle and Heliflyg to Osterman Helicopter.
