Adds massive cargo ships to the game, that function similarly to trains. Also adds deep sea oil, oil platforms, tanker ships, train bridges and other water based content.
Whenever I view another surface through the space exploration wiki, more offshore oil wells spawn on nauvis instead of the new surface. View enough worlds and soon nauvis is covered in offshore oil fields and the fish start rising. The oil wells should probably spawn on the layer that is generating them instead of assuming nauvis is the only layer.
