Maersk Triple E class
The Mærsk McKinney Møller during first startup in Bremerhaven
The ships of the Triple-E class the Danish shipping company Maersk Line is the world's largest container ship type. The name derives from the three underlying the design principles "Economy of scale" ( German: scale effect ), " Energy efficient" ( German: energy efficiency) and "environmentally improved" ( German: improved environmental friendliness ) from.
Procurement and deployment
Commissioned the series of ULCS units is the Copenhagen-based Maersk Line. The end of February 2011 georderte series will be delivered in June 2013 the South Korean shipyard Daewoo Shipbuilding & Marine Engineering ( DSME ). Between 2013 and 2015, first to ten ships of the type to be built; the price is around 190 million U.S. dollars per unit. On 27 June 2011 the option for the construction of the existing of a further ten ships second batch was redeemed in Tokyo. A temporary option until February 2012 for the construction of a further ten ships of the type, however, was not perceived by Maersk.
The plan is to ship for use on the route between Asia and Europe, as there are no suitable for this size of ship ports so far in North America. The only German port, the ships are fully loaded to start is the JadeWeserPort opened in 2012 in Wilhelmshaven, is involved in the Maersk with 30 percent.
The lead ship of the series, the Mærsk Mc- Kinney Møller was named after the 2012 verstorbenenen chairman of the Mærsk Group. The baptism took place on June 14, 2013, the ship was delivered on 2 July 2013. Two weeks later, the ship began her maiden voyage from Busan ( South Korea ) to Rotterdam and Bremerhaven.
Technology
Ship Structurally remarkable is a series of innovations and details that were, for example, already used in the somewhat smaller series of the CMA CGM Christophe Colomb - class. The deck house, unlike the majority of the conventional container ships, arranged far forward, which enables an improved line of sight, and thus a higher loading of the deck Vorschiffsbereiches. Below the structure, among others, the bunker tanks are arranged to meet since August 2007 valid MARPOL regulation 12A.
In addition, the machinery was located so far aft as possible, thereby shorter and thus more space-saving drive shafts were built, which in turn enabled additional container storage. The construction of the triple- E class with two motors enabling the insertion of two low-speed propeller of larger diameter, having a higher efficiency than a single rapidly rotating propellers. Both Triple-E - propellers have a slightly larger diameter and put together a more than twice as large propeller area as the single-propeller of ships of the Emma Mærsk - class. In addition, the Triple-E class is designed for an economical driving slower (slow steaming ). Compared to the maximum speed of 25 knots is the fuel economy at 22.5 knots 20 percent, are 50 % at 20 knots and 37% at 17.5 knots. The ship's engines are designed for optimum speed of 19 knots. On July 7, 2011 Maersk has been used for the Triple-E class with the Sustainable Shipping Operator of the Year Award ( approximately: Price as a sustainable Ship Operator of the Year ) honored. The exhaust gases of the two main engines produce exhaust gas boilers steam, with the steam turbine drives a generator. The electrical energy can be fed back into the drive system. Overall, the fuel consumption is two-stroke engines with a long stroke, exhaust heat recovery, lower service speed and additional transport capacity compared to the ships of the Emma Mærsk class will be reduced by about 20 percent per container by the two propeller concept with slow speed ( 80/min ) (which would be 2.1 liters of heavy fuel oil per 14 tonnes of heavy container per 100 kilometers and 24 knots speed).
Except for the length of the ship and the depth the characteristics of the double-hull vessels in part extend well beyond those of all previously built container ships. With a length of almost 400 meters, a width of 59 meters and a height of 73 meters, a truncated form of relatively large block coefficient was chosen. With a carrying capacity of 18,270 TEU units of the Triple-E class exceed those of the biggest container ships CMA CGM Marco Polo type by 13 % and 2220 TEU. In addition, they are equipped with a capacity of 1800 reefer containers ( according to the ships of the Cap- San -Class (2100 connections) the shipping company Hamburg -South ) is the second largest refrigerated container ships worldwide (as of mid 2013).
The holds of the vessels are closed with pontoon hatch covers.
