Emissions

Triple-E to cut CO2 emissions in half. Its size is remarkable, but this is not the Triple-E’s true claim to fame.

Triple-E: Emissions

The big news is that this big ship does not pollute as much as you would expect. In fact, Maersk Line’s new vessel will cut carbon dioxide emissions by more than 50 percent for every container it moves, compared to the industry average on the Asia-Europe trade.

The 20 Triple-E ships will sail between Asia and Europe, carrying larger loads than Maersk Line’s current E-class vessels – but at less cost to the environment.

Reducing our CO2 footprint is a top priority for us and also our customers who depend on us in their supply chain

Size is important – the Triple-E can carry 2,500 more containers than E-class ships – but that’s certainly not all. The Triple-E’s energy efficiency can be explained by its two slow-running engines, twin propellers and waste heat recovery system.

Maersk has set itself stiff targets – to reduce CO2 emissions per container moved by 40 per cent by 2020, compared to 2007 levels – but it is well on the way to success (read more here).

So far the company has reduced its CO2 emissions by 25 per cent. This does not take into account the expected gains from the Triple-E, which will take Maersk Line even closer to its 2020 goal.

FACTS: The Triple-E ships sets new standards for transport efficiency

  • The Triple-E class of container ships will be the most energy efficient in the world.
  • Its scale: with a total capacity of 18,000 20-foot containers – 16 percent more than E-Class vessels – it will cut CO2 emissions per container-kilometre
  • A combination of two smaller engines and two propellers: The two propulsion systems allow for a lower number of revolutions of the engine, resulting in more than 10% energy savings
  • Waste heat recovery: all Maersk Line vessels on order will be equipped with a waste heat recovery system, which uses hot exhaust gas to provide extra propulsion for the ship. Without this, the Triple-E’s fuel consumption and CO2 emissions would be approximately 9 percent higher
