We are doing construction on an alien world with unbreathable air
This creates a very big problem for a growing city which needs to expand. Workers cannot go outside safely for long periods. Goal: Minimizing outside time and staying inside a climate-controlled environment reduces injuries to workers. Anything that makes the job easier makes it faster.
I want to reduce ground crews by simply flying overhead with tethered construction airships.
- Assume no wind hazards. Winds are moderate and manageable, no storms on record.
- Airships can be tethered to the ground for better stability, but the gas bags provide the lift.
- Likely, the hoist can move around on tracks as well rather than maneuvering the whole ship.
The several disadvantage to heavy ground equipment I feel could be addressed this way are:
- Erecting a bridge or tower crane requires a large team working outside.
- Rigging cranes with counterweights, and assembling their masts on the ground.
- Large cranes need smaller crawler cranes to build them; Poor viewing angle to the hook and load make errors more likely.
These are the things I can think of. But a construction airship will likely need to be designed differently than the passenger liners we are familiar with. I don't know what those differences may be, but it seems that in general, airships can provide a much safer work environment at large construction projects in unbreathable air.
What might be the pitfalls, or what should they be prepared for?
- Air density = 15 kg/m$^3$
- Terrain = rocky
- Buildings considered:
- Large open space / covered colosseum of 10 acres
- 20-story masonry buildings (which will be domed over)
- Framed biodome covering 30 acres
