    They run on this lovely environmental disaster of a fuel:

    Heavy fuel oil is a category of fuel oils of a tar-like consistency. Also known as bunker fuel, or residual fuel oil, HFO is the result or remnant from the distillation and cracking process of petroleum. For this reason, HFO contains several different compounds that include aromatics, sulfur, and nitrogen, making emissions upon combustion more polluting compared to other fuel oils.
