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.
The left and upper sides of the oil well platform are only covered with one grid, and the right and lower sides are covered with two grids (I need to put an oil tank to detect the crude oil stock, and when there are enough oil tanks, I will assign oil tankers to come)
Because the oil platform could not connect the signal line to detect the oil stock, it had no choice but to fill the sea nearby and place the liquid irrigation
