Aircrafts is a resource to an airline as in any other industry. But in this case the value of the resource is more concentrated and needs constant upkeep to sustain their value. When repairs and service are performed on an aircraft they are often stored in aircraft hangars. The reasons for this is are both for security measures and weather protection since they contain sensitive equipment.
Well inside the hangars there is also the risk of fire due to fuel leaks and other hazardous substances. This needs to be countered by an efficient fire suppression system which minimizes the the danger to human life and economic consequences.
Norwegian has recently expanded their operation a great deal with a massive purchase of 222 jets for their fleet in 2012, including several new Boeing 787 Dreamliners. As the aircrafts purchased are being delivered and put into action they in turn need to be serviced and kept problem free. Norwegian has recently built one of their hangars for these purposes in Gardemoen, Norway which Incendium got the honor of providing protection for.
