"How do I transport my housing securely?"
The best are light well padded bags in backpack form in which you can store your entire equipment in a nice and clear order. When travelling by air, make sure you take your equipment into the cabin. If this is not possible then remove the front port or main O-ring in order to avoid damages due to increased inner housing pressure and then shut your housing as usual. If you are on a ship, choose the most stable area on board and place your equipment on the floor so it cannot fall down during rough sea.
