The Danish company Maersk Line recently signed a contract with Korea’s Daewoo Shipbuilding and Marine Engineering to build 10 Triple-E shipping vessels. When they are finished, these will be the largest oceangoing ships ever created and are designed to each hold 18,000 20-foot containers. This is 16 percent more capacity than today’s largest container vessels. The Triple-E name stands for economy of scale, energy efficiency, and environmentally improved. The specific diesel engines have not been announced, but many industry experts believe two MAN G-Type ultra-long-stroke diesels (producing about 42,204 hp each) will get the nod. Economy of Scale According to Maersk Line, 90 percent of all goods in world trade are transported in 20-foot containers. Therefore, increased shipping capacity means more freight hauled with less energy being spent. The economics of this suggest a 20 to 30 percent cost reduction because the amount of product moved goes way up per trip. The dimensions of the new Triple-E ship will not be significantly increased beyond the second largest ship on the sea. Instead, an innovative U-shaped hull and rearranged engine setup will be used to create the extra space. Triple-E Spec: Vessel: Triple-E Owner: Maersk Line Manufacturer: Daewoo Shipbuilding and Marine Engineering Scheduled for delivery: 2013 Cost: $190 million per vessel Length: 437.44 yards (400 meters) Beam (width): 193.57 feet (59 meters) Height: 79.83 yards (73 meters) Draught: 47.57 feet (14.5 meters) Deadweight: 165,000 metric tons Reefer container capacity: 600 Top speed: 23 knots Crew: Normal operation 19 (possible to operate with 13) According to Maersk, the Triple-E class of container vessels will emit 50 percent less CO2 than the industry average for vessels operating on the Asia-Europe trade route. According to Maersk, the Triple-E class of container vessels will emit 50 percent less CO2 Energy efficiency comes from the Triple-E’s twin-skeg propulsion system, which uses two engines and two propellers instead of the conventional one. The Triple-E’s two propellers are 35.15 feet in diameter with four blades each. The powerplant is an ultra-long-stroke diesel engine, operating with a lower number of revolutions than a traditional engine. This megaship is designed to move through the water at a slower speed (reduced 2 knots). This small decrease in speed reduces fuel consumption, as well as the power needed to push the ship by 19 percent. Energy efficiency comes from the Triple-E’s twin-skeg propulsion system, which uses two en At 437.44 yards (400 meters), the Triple-E will be the largest ship ever built. For comparison purposes, the USS George H.W. Bush aircraft carrier (1,092 feet long) is 220 feet shorter than the Triple-E. At 437.44 yards (400 meters), the Triple-E will be the largest ship ever built. For compar According to Maersk Line, if all the containers the Triple-E can carry were put on a single train, that train would need to be 68.3 miles long. According to Maersk Line, if all the containers the Triple-E can carry were put on a singl The specific powerplant has not been announced, but two slow-speed two-stroke diesel engines will be positioned toward the rear of the Triple-E. The ship’s design requires about 80,428 hp.
