The Maersk Triple-E vessels are the largest shipping container ships in the world and there are several design reasons why.
Ok not going down the route of the obvious being “its bigger” but there are some design features including the altering of the hull shape to allow more cargo to get carried as its designed to go slow and work more efficiently. Sacrificing some aerodynamics to gain space at the same time the ship is designed for load not speed.
I think when Maersk started looking at the Triple-E vessel they were realising the world markets were changing and being more efficient doesn’t just lead to reduced running costs but adapting with a changing market. Going bigger than other large container ships that it has in its fleet while getting running costs down have been a major feat in the success of the Triple-E vessel.
Another interesting feature of the Triple-E vessel the largest container ship in the world is that as speed is not its primary goal optimisation of its fuel use has taken more of a priority and they actually utilise the exhaust gases to make more energy making it one of the most efficient ships on the planet.
What many people don’t realise is due to the scale of ships the faster they go the bigger the Co2 problem becomes. Not in that 1 knot = 1 pollution but as you increase in speed the problem of Co2 emissions magnify to a much larger scale. Making a ship that runs at lower speeds and more efficiently reduces this problem and this is partly why the Triple-E vessel has become a world class leader in efficient shipping. What this realistically means that we are seeing on average a 50% reduction in Co2 per container moved from Asia to Europe.
The worlds largest container ship Co2 emission comparison against other transportation.
- The Maersk Triple-E vessel has 3g of Co2 per container per 1 Km.
- Average train has 18g per 1km Co2 emissions per container moved.
- Truck 47g of Co2 emissions per 1km travelled per shipping container.
- Airplane 560g of Co2 emissions per 1km travelled.
All in all you can see why shipping is one of the most efficient ways to transport goods but also why the largest shipping container in the world is also extremely green.
