context_page_description: The Triple E class is a family of very large container ships of more than 18,000 TEU belonging to Maersk.
  With a length of 399.2 m, when they were built they were the largest container ships in the world, but were subsequently surpassed by larger ones such as CSCL Globe.
  In February and June 2011, Maersk awarded Daewoo Shipbuilding & Marine Engineering two US$1.9 billion contracts to build twenty of the ships.
  The name "Triple E" is derived from the class's three design principles: "Economy of scale, Energy efficient and Environmentally improved".
  The ships are 399.2 metres long and 59 metres wide. While only 3 metres longer and 4 metres wider than the Mærsk E class, the Triple E ships are able to carry 2,500 more containers. With a beam of 59 metres, they are too wide to traverse the Panama Canal, but can transit the Suez Canal.
  One of the class's main design features is its dual 29.68-megawatt ultra-long stroke two-stroke diesel engines, driving two propellers at a design speed of 19 knots. This class is by design slower than its predecessors, using a strategy known as slow steaming expected to lower fuel consumption by 37% and carbon dioxide emissions per container by 50%.
