The MV Maersk Mc-Kinney Moller, the world's biggest container ship, arrives at the harbour of Rotterdam August 16, 2013. The 55,000 tonne ship, named after the son of the founder of the oil and shipping group A.P. Moller-Maersk, has a length of 400 meters and cost $185 million. A.P. Moller-Maersk raised its annual profit forecast for the business on Friday, helped by tighter cost controls and lower fuel prices. Maersk shares jumped 6 percent to their highest in 1-1/2 years as investors welcomed a near-doubling of second-quarter earnings at container arm Maersk Line, which generates nearly half of group revenue and is helping counter weakness in the company's oil business.
