Space has developed with American Blimp Corporation a system for heavy lift transportation over short and medium distances with tethered balloons.
Brazilian Civil Aviation Agency has specific regulation for this kind of operation with tethered balloons in the national territory (RBHA 101), establishing operation and safety limits.
The Command of the Air Force through the Department of Airspace Control (DECEA) also has a regulation defining signaling required and geographical limitation for this activity.
This activity clearly requires knowledge of the system of aerial navigation and operation of artifacts in Brazilian airspace, which is under routine activities of specialized aviation companies such as Space Airships.
On the other side, the operation of a Cargo Tethered balloon, requires a great level of experience in dealing with composite fabric envelopes filled with helium gas, "ballonets" internal air, control cables and suspended load modules. It also includes the handling of integrated pressure valves, while keeping the aerostatic system balance using ballasts.
These peculiarities are not much different from blimp operations, which are likewise composed of: helium fabric balloons; controllable air envelopes; control cables; and suspended loads. Blimp operations also include engines and surfaces control.
Besides the aspects listed above, aerostats or airships, requires experience in dealing with the weather challenges, especially regarding the wind which plays significant role on the operational safety.
The tethered balloon projected by the ABC and Space Airships to be used in Petrobras Refinery of Manaus (REMAN) revamp has more than 20,000 m3 of helium and at least twenty percent of this amount of compressed air. It sizes roughly a ten story building.
The largest aircraft static systems used in Brazil till today were the blimps A-60 PR-MKJ of 3,000 m3 and A-150 PR-ANA of 4500 m3, manufactured by American Blimp Corporation and operated by Space Airships from 2002. Space flew more than 12,000 hours in these models, during ten years, throughout the national territory, without any incidents or accidents.
Space Airships is therefore the only aviation company with experience in commercial operation of any kind of aerostatic systems (blimps) in Brazil and throughout South America. Its operational standards are supervised by The Lightship Group (largest operator of airships in the world, with more than 350,000 of flight hours). And their equipment is manufactured exclusively by American Blimp Corporation (main airship manufacturer in the world).
In addition to its unique expertise in airship operations, Space Airships was also recognized by Petrobras Legal Department as the only company currently able to conduct tethered balloons operations in Brazil.
