Oslo Airport

Avinor AS is a state-owned, limited company that owns and operates 46 airports in Norway. That includes the Oslo Airport, the second-busiest airport in the Nordic countries, with 24 million passengers and 245,000 aircraft movements every year.

The challange

Avinor has long relied on a facility-wide supervisory system to control and coordinate the many airport functions. Avinor needed to enhance system security while ensuring that the system continues to provide highly reliable control of these functions. They also needed to ensure that the system is able to accommodate a significant airport expansion in the near future. 

The solution

Airports represent a complex operating environment with many separate areas and functions that must be controlled and coordinated. At Oslo Airport, each of those functions – including baggage, departures, doors, HVAC, fire/security, and others – are controlled locally via a technical management system (TMS). Those subsystems, 23 in all, roll up to a superior SCADA system, the airport’s central technical maintenance system (CTMS).

At the Oslo airport, the CTMS is Hitachi Energy Network Manager

“Network Manager primarily serves as the process data center for the entire airport,” says Arne Saugstad, a senior sales executive for Hitachi Energy's Enterprise Software product group. “It also provides central control of the subsystems and, through Network Manager’s advanced alarm processing, enables a single, centralized alarm system. It also serves as the conduit for sharing information across those subsystems. The CTMS comprises approximately 55,000 indications (e.g., on/off, open/closed), measurements (e.g., temperature, pressure, RPM), and setpoints for process controls.”
