Some of Queen Mary 2's facilities include fifteen restaurants and bars five swimming pools a ballroom a theatre and the first planetarium at sea.
She was designed in 2003 by a team of British naval architects led by Stephen Payne and was constructed in France by Chantiers de l'Atlantique. At the time of her construction Queen Mary 2 held the distinctions of being the longest at 1131.99 ft (345.03 m) and largest with a gross tonnage of 148528 GT passenger ship ever built. She no longer holds this distinction after the construction of Royal Caribbean International's 154407 GT Freedom of the Seas in April 2006 but remains the largest ocean liner ever built.
Queen Mary 2 was intended for routine crossings of the Atlantic Ocean and was therefore designed differently from many other passenger ships. The liner's final cost was approximately $300000 US per berth. Expenses were increased by the high quality of materials and having been designed as an ocean liner she required 40% more steel than a standard cruise ship.Queen Mary 2 has a maximum speed of just over 30 knots (56 km/h; 35 mph) and a cruising speed of 26 knots (48 km/h; 30 mph) much faster than a contemporary cruise ship. Instead of the diesel-electric configuration found on many ships Queen Mary 2 uses integrated electric propulsion to achieve her top speed. Diesel engines augmented by gas turbines are used to generate electricity for electric motors for propulsion and for on-board use.
Engineering projects around the globe keep getting bigger and more ambitious. , there are structures being designed and built that will dwarf anything that has come before. Plans are on the drawing board for projects so huge not only in scale, but in their implications for society they’re almost beyond imagination. This Good Engineering documentary, that eyes the largest construction projects ever imagined 'Good Engineering.
