Unless you're using a console version there is a cheat that will turn you invisible (but your vehicles are still visible), or alternatively a code to remove damage. But I wouldn't suggest you start using it because it ruins the whole experience of the game. Read the wiki and compile the number of biomes that can have engine fragments and pick the safest option. One you have the cyclops and a seamoth with suitable depth level / prawn suit, take it out into the sea treader's path caves. Tonnes of ruby there and no warpers inside the massive cave.
