Triple-E vessels 

The Triple-E is the largest ship in the world, and it sets new standards in the container industry, not just for size, but also of energy efficiency and environmental performance. With unique design features for slower speeds and maximum efficiency, vessels in this series emit 50% less CO2 per container moved than the current average on the Asia-Europe route.

Maersk Line has ordered a total of 20 of these vessels, which will be phased in gradually over the next couple of years on the existing route between Asia and Northern Europe (AE10).


Four hundred meters long, 59 meters wide and 73 meters high, the Triple-E will be the largest vessel of any type on the water to date. Its 18,000 TEU (twenty-foot container) capacity is 16 % greater (2,500 additional containers) than our largest container vessels like Emma Maersk from the Maersk E-class type.


The Triple-E's are designed with a 'twin-skeg' propulsion system (two-engine, two-propeller). The Triple-E's two propellers are 9.8 meters in diameter with 4 blades each. The engine is an ultra-long-stroke engine, operating with a lower number of revolutions compared to a traditional engine. The total power is appr. 30,000 kW per engine.

Capacity and hull specifications:

The hull of the Triple-E is more like a U-shape compared to traditional container ships. An additional row of containers has been added to the Triple-E, giving it 23 rows across its width, compared to 22 rows onboard Emma Maersk. The more spacious hull and extra row provides additional capacity and with the more forward navigation bridge, containers can be stacked higher in front of the bridge without losing visibility. In addition to that, more containers fill the space behind the bridge above deck and below deck, using the space created by the engine room's position further to the back of the vessel.

Principal measures of the Triple-E include:

• Beam (breadth): 59 meters
• Draught: 14.5 meters
• Deadweight: 165,000 metric tons
• Reefer container capacity: 600
• Top speed: 23 knots
