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 through the water require immense amount of energy, that are derived from massive diesel engines. Some of the larger cargo ships have engines that look like this.
The 14-cylinder version was put into service in September 2006 aboard the Emma Mærsk, a container ship – the largest at that time. The design is based on the older RTA96C engine, but revolutionary common rail technology has done away with the traditional camshaft, chain gear, fuel pumps and hydraulic actuators. The result is better performance at low revolutions per minute (rpm), lower fuel consumption, and lower harmful emissions.
