Emma Mærsk
The Emma Mærsk in Aarhus September 5, 2006
The Emma Mærsk - class is a series of eight identical container ships in the Danish shipping company Maersk, which were built at the shipyard Odense Staalskibsværft. From 2006 until the commissioning of the CMA CGM Marco Polo in November 2012, it was the largest ships of its kind
Particulars
The lead ship of the class, which is called the PS series, the Emma Mærsk. The ships belonging to the Post-Panamax class were found between early September 2006 (Emma Mærsk ) and early 2008 ( Eugen Mærsk ) in service. The ships of the Emma Mærsk - class because of their size and make refinements to the hull the lowest resistance value per ton of repressed all container ships.
The Emma Mærsk was completed because of a fire during construction with a two-month delay in August 2006 in the Group's own shipyard in Odense / Denmark. It has a length of 397 m and a width of 56.4 m, which surpasses the lying second MSC Danit to 5 m in width. The load capacity is 156 907 DWT. The top speed is about 26 knots at design draft. The ship can load according to official figures 14.770 20 -foot standard containers (TEU), of which 1,000 refrigerated containers. The difference between the previous data of 11,000 TEU and the actual size information arises from the fact that the shipping company Mærsk always laden, 14 -ton containers go out in their statements to the cargo capacity of a container ship, while other shipping companies specify the maximum number of containers that the on have space ship. The Emma Mærsk is the first ship of this new order, for which the deep water port in Wilhelmshaven was built. The turning area in front of the quay of the CT Bremerhaven in the Weser had been widened extra for the Emma Mærsk 600 m. The 135 -ton propeller has been made in Waren ( Müritz) at the Mecklenburg Metallguss. This is the largest and heaviest propeller ever built. The underwater hull was fitted with a silicone coating, which saves up to 1,200 tons of fuel annually, according to the shipping company.
Ship propulsion
The main drive of the vessels is performed by a fueled with heavy oil, turbocharged two-stroke crosshead engine by the Finnish manufacturer Wärtsilä (type 14RT - flex96C ) with 14 cylinders and an output of 80.080 kW ( 108 878 PS). The engine weighs 2300 tons, the crankshaft alone weighs 300 tons. It must transmit a torque of 7,500 kNm at 102/min. At full power (Brake Specific Fuel Consumption) is its fuel consumption at 0.171 kg / kWh, which is equivalent to around 14,380 liters of fuel per hour. This gives 2.7 liters of heavy fuel oil per container with 14 t and 100 km of transport. The relatively low consumption of the diesel engine is related to its high efficiency of 49.0 percent. Modern car engines are still only at 35 to 45 percent.
The bore of the engine is 96 cm, the stroke of 2.50 m. This results in a displacement of 1,809 l and 5,720 kW per cylinder. Extrapolated results in the 25,320 l capacity with 14 cylinders.
For mooring the Emma Mærsk has four thrusters.
Exhaust heat recovery
In addition, two auxiliary electric drives ( shaft motors ) can be connected to the main drive shaft with a total output of 18,000 kW. They receive the electric power in the ideal case by the exhaust heat recovery generator, which is driven by the exhaust gas turbine and the steam turbine with 8,500 kW. It may also e- power is fed by the diesel generators of type Caterpillar MAK 9M32, each with 4,148 kW.
The exhaust heat recovery ( Waste Heat Recovery ) converts at rated power of the main motor, the machine waste heat with a turbine-driven generator into electrical power to. Thus, the total power of the system to 9,860 kW or 12.0 percent is increased and the specific consumption decreases to 0.158 kg / kWh. For this purpose, a part of the exhaust flow rate to the exhaust gas turbocharger by, as well as the exhaust gas from the turbocharger and the auxiliary diesel engine to an exhaust gas turbine directed force acting on the generator via two gear stages. In addition, a large two -pressure exhaust gas boiler with economizer and superheater was installed. The superheated steam generated in a steam turbine mechanical power acting on a gear stage on the same generator. Thus, the overall efficiency of the machinery rises to around 55 percent.
Routes
All eight of Emma Mærsk class 2011/2012 mainly used on the route between AE10 Gdansk in Poland and Shanghai in China. The exact route:
Danzig - Aarhus (Denmark ) - Gothenburg (Sweden) - Bremerhaven ( Germany ) - Rotterdam (Netherlands) - Algeciras ( Spain) - Suez Canal - Singapore - Yantian (China, Port of Shenzhen) - Hong Kong (China ) - Shanghai (China) - Gwangyang (Korea ) - Ningbo (China ) - Shanghai.
On the way back to Europe, Singapore will no longer be running and Hong Kong only a few rides. For Tanjung Pelepas ( bordering directly to Singapore, Malaysia ) and isolated Zeebrugge (Belgium ) is underway.
A revolution takes this manner; ten weeks so that almost every week a ship of Emma Maersk class in Bremerhaven container terminal at the IV ( it is in operation since September 2008 ) can be seen. The port - deck times are between 18 hours in China and 45 hours in Bremerhaven.

The ships
Eight identical ships were built:
Others
The end of 2006 transported the Emma Maersk on their way to southern China thousands of tons of British waste for recycling to China. When this became public knowledge through media reports, China's state environmental agency assured, they 'll be watching the way forward these wastes critical.
In February 2013, the engine room of the Emma Maersk was full of water. She had to be dragged out of the Hauptschifffahrtsweg of the Suez Canal. First, the destroyed stern thruster was sealed to prevent the containers reloaded and the ship can be repaired, said a spokesman for the cruise line. The end of February the ship reached Palermo ( Sicily) and was repaired there until July 2013.
