If you want to move oil… you should think about the pipeline. It is currently moving around 70% of all oil (in ton-mile measurements)
The fixed cost of getting the oil into the pipe and maintenance is the highest… but the variable cost is the lowest.
The big pluses are that its ability to run 24/7 and there are no emissions, or vehicles to return.
The negative is that it can only move certain products such as liquids and gases.
