Conceptually, you don't need to fully land the craft. If you lower the payload by cable, those cables are your anchor line. Then you adjust buoyancy until you're no longer straining against the cables, cut anchor, and float away.

Can an airship compensate for 60-75 tonnes of buoyancy change? Releasing helium sounds expensive.

  You could load ballast (maybe water) as you unload the cargo.

  Looks like the ballpark of $100k per metric ton, definitely not something you want to vent if you can help it.

  you don't need to vent it if you can compress it. 1 cubic meter of helium replaced with 1 cubic meter of air raises the weight of the craft by ~1.5 kg. That means we need to be able to reduce our helium volume by 50,000 m^3. If (optimistically) we can pressurize the helium to 2 atmospheres, then we only need a 100,000 m^3 envelope. Which is huge, but half the size of the Hindenburg. Realistically, we'd probably get worse compression than that, but it's within an order of magnitude of feasible.
