Here are a few interesting facts about this massive cargo freighter:

• The Danish company Maersk is building a total of 20 of these biggest ships, Triple-E, on a dry-dock in South Korea. Apparently the first one, named McKinney Moller, has hit the high seas already. Watch the big beauty float its way through the Suez canal on its way to Europe.
• Cost of each ship is $185 million and expected to ply the route between Northern Europe and China.
• Stood on its stern, its bow would stretch 19 meters above the roof of the Empire State Building.
• In one trip, a Triple-E could transport more 182 million iPads, or 111 million pairs of shoes, from Shanghai to Rotterdam.

One giant container ship can emit almost the same amount of cancer and asthma-causing chemicals as 50m cars, study finds

The Guardian has a pretty shocking piece about giant cargo ships and the pollution they emit. The title of this post is a line from “confidential data from maritime industry insiders”, and according to them, the low-grade ship bunker fuel that powers cargo ships has up to 2,000 times the sulphur content of diesel fuel used in US, and European automobiles and emission control is practically non-existent.  Here we can see that the primary concern with shipping is air-pollution (“US academic research which showed that pollution from the world’s 90,000 cargo ships leads to 60,000 deaths a year in the US alone and costs up to $330bn per year in health costs from lung and heart diseases”). It does contribute significantly to global warming, but about 5-6 times less than land-based transportation.

Shipping by numbers (From Guardian)The world’s biggest container ships have 109,000 horsepower engines which weigh 2,300 tons.

Each ship expects to operate 24hrs a day for about 280 days a year

There are 90,000 ocean-going cargo ships

Shipping is responsible for 18-30% of all the world’s nitrogen oxide (NOx) pollution and 9% of the global sulphur oxide (SOx) pollution.

One large ship can generate about 5,000 tonnes of sulphur oxide (SOx) pollution in a year

70% of all ship emissions are within 400km of land.

85% of all ship pollution is in the northern hemisphere.

Shipping is responsible for 3.5% to 4% of all climate change emissions

The calculations of ship and car pollution are based on the world’s largest 85,790KW ships’ diesel engines which operate about 280 days a year generating roughly 5,200 tonnes of SOx a year, compared with diesel and petrol cars which drive 15,000km a year and emit approximately 101gm of SO2/SoX a year.
