Nothing important (including freeze tubes) should be on a mobile facility long term. Too hard to control, too hard to maintain, not very durable, more at the mercy of the elements, etc. If you want an unmanned sensor or comms station on an oil rig, sure - you've got an overfilled network, you can lose a few without impacting operations. But don't freeze people on an oil rig for 20 years.
