It's been a while since you posted, so I assume you've figured this out by now, but since you never posted a response, I'll post this here for posterity.

The Tiled editor is only for editing the dungeon part JSON files under /dungeons and the tileset JSON files under /tilesets. It is not able to open any other Starbound files. The .world files, including your shipworld, use a custom format called BTreeDB5. There is, unfortunately, no known way to edit this format outside of Starbound. The py-starbound project is able to read the format, but not alter it, and that project hasn't been updated in over 4 years.

I really wish it were possible to safely edit BTreeDB5 files, because Starbound has a bug in which these files grow continuously as long as you're on the world. Something in their code is not properly garbage collecting, so the files eventually become enormous with dead code, and currently the only thing you can do about it is to delete them and allow the game to regenerate them, thereby losing any customizations you had made to the worlds.
