The first of 20 giant Triple-E ships for Maersk Line comes out of Daewoo Shipbuilding & Mechanical Engineering Co. drydock for fitting out alongside.
The name "Triple E" is derived from the class's three design principles: "Economy of scale, Energy efficient and Environmentally improved". These ships are expected to be not only the world's largest ships in service, but also the most efficient containerships per twenty-foot equivalent unit (TEU) of cargo.
The ships will be 400 metres (1,312 ft) long and 59 metres (194 ft) wide. While only 3 metres (9.8 ft) longer and 4 metres (13 ft) wider than E-class ships, the Triple E ships will be able to carry 2,500 more containers.
One of the class's main design features are the dual 32 megawatts (43,000 hp) ultra-long stroke two-stroke diesel engines, driving two propellers at a design speed of 19 knots (35 km/h; 22 mph).
