Emma Mærsk Worlds Largest Container Carrier

General introduction

• The ship is named after Emma Mærsk, Mærsk Mc-Kinney Møller's late wife. M/S EMMA MÆRSK is a very large container ship, and has been built applying the newest technology in design and equipment. 

• The ship can therefore be operated by a crew of 13 persons only. Accommodation is arranged for 30 persons. 

General introduction (2)• The life-saving equipment consists of two 38 persons’

lifeboats, six life rafts and one man-over-board boat (“MOB”).

• The latest radio, telex, telefax, and satellite telephone systems ensure efficient communication to the world.

• An air conditioning system gives comfortable indoor temperatures regardless of outside weather.

• Combined with a low level of noise and vibrations this ensures ideal conditions for both work and leisure.

• M/S EMMA MÆRSK is designed and built to meet the highest demands for safe, precise, environmentally friendly and economic transportation of goods all over the world. 

Emma Maersk engine dataThe Emma Mærsk is powered by a Wärtsilä-Sulzer 14RTFLEX96-C engine (14 cylinders), currently the world's largest single diesel unit, weighing 2,300 tons and capable of 110,000 horsepower at 102 RPM (82 MW). Engine length is 89 ft, and height is 44 ft. The cylinder bore is just under 38" and the stroke is just over 98". Each cylinder displaces 111,143 cubic inches (1820 liters) and produces 7780 horsepower. Total displacement comes out to 1,556,002 cubic inches (25,480 liters) for the fourteen cylinder version.

 The smoke stack

Traditionally ships are painted with a poisonous paint meant to keep of growth, which produces drag thus increases fuel consumption. This paint must be refreshed ever so often, constantly introducing more poison to the sea. This traditional paint is knows as biocides. Instead of biocides on Emma, a special silicon-based paint is used. This increases the ship's efficiency by reducing drag while also protecting the ocean from biocides that may leak. The silicon paint covering the part of the hull below the waterline is credited for lowering the water drag enough to economize 1200 tones of fuel per year.

 The Hull

Propeller data

The shaft system extents from the main engine via two 9MW electric motors, and to the propeller. The total length of the shaft system is 120 meters, and it weighs in at a staggering 605 tons! The Emma Maersk propeller is an MMG six bladed, one-piece, fixed pitch propeller, which weighs in at 131 tons. The diameter is 9.6 meters.

Yard fire• In June 2006, during construction, welding works caused

a devastating fire in the accommodation quarters in the early days of June.

• A welding job on the main deck, close to the end of working hours, led to a fire that totally destroyed the almost finished accommodation quarters and all the equipment in the wheelhouse.

• Shipyard Baltija at Klaipeda – where the accommodation quarters were built and equipped – had to speed up the process and then Emma Maersk was shipped to Odense.

• Two Dutch floating cranes shifted the quarters in mid July. The old, burnt out quarters were sold to the nearby recycling company H. J. Hansen for demolition.
