Container ships are some of the largest and heaviest vessels that plough on the seas.  They measure up to 1,200 feet in length and can move 10,000 to 16,000, 20-foot steel containers in one trip.  To push these vessels though the water they require an immense amount of energy that they get from massive diesel engines.   The world’s biggest engine is the Wartsilia-Sulzer RTA96.

One of the most remarkable feature of this mammoth contraption is the high thermal efficiency, which exceeds 50%.  This means that 50% of the heat generated by burning fuel is converted to power.  For comparison, most automotive and small aircraft engines can only achieve 25-30% thermal efficiency.  Even at its most efficient power setting, the big 14 cylinder engine consumes 1,660 gallons of heavy fuel oil per hour.
