It is the base for a Eurocopter EC-135P2+ operated by Norsk Luftambulanse (NLA) for the Norwegian Air Ambulance.

Grønneviksøren is also used by the Royal Norwegian Air Force's 330 Squadron's Westland Sea King search and rescue helicopters.

Grønneviksøren is located 2 kilometers (1.2 mi) from the hospital and patients must therefore be transported by ambulance to Haukeland.

In 2002 the owner of the lot, Bergen Municipality, signed an option to allow Bergensia Badeland to build a swimming pool at the site.

There was a three-month resignation clause in the rental agreement, and Bergen Heath Trust, which had taken over the ownership of the hospital that year, therefore decided that it would need to move the heliport to Grønneviksøren.

They had a temporary structure, although it did not allow good landing conditions and was considered hazardous for flight safety.

[8] The heliport is situated at Grønneviksøren on the southern shore of Store Lungegårdsvannet in the Årstad borough of Bergen.

It features a single landing pad, which measures 60 by 34 meters (197 by 112 ft), a hangar, a fuel tank and offices.

[9] About sixty percent of all air ambulance missions to Haukeland land at Grønneviksøren, the remainder directly targeting the hospital.

The ambulance ride increases travel time by ten to fifteen minutes and the physician on board will make the decision based on the condition of the patient.

The Civil Aviation Authority has in its concession limited the number of aircraft movements at the hospital to 400 per year, which forces Haukeland to revert the majority of flights to Grønneviksøren.
