Container ships are some of the largest and heaviest vessels that plough on the seas.
Some of the larger cargo ships have engines that look like this.
Standing at 13.5 meters high and 26.59 meters long, it is almost as big as a small apartment.
It weighs over 2,300 tonnes and its largest 14-cylinder version produces 80,080 kW of power.
One of the most remarkable feature of this behemoth 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.
