The bubble system also reduces propeller noise, and is used on Celebrity Reflection and Quantum of the Seas. Small air bubbles from the keel reduce drag and thus fuel consumption by 7 to 8 percent, and a smooth hull surface further reduces resistance. Harmony of the Seas is 20 percent more energy efficient than her sister ships Oasis of the Seas and Allure of the Seas. She also has 20 dining venues, a 1,400-seat theatre and 11,252 works of art. It also has the first water slides on a Royal Caribbean ship. Harmony of the Seas has a number of water-based attractions including a large dry slide complex, known as The Ultimate Abyss, two surf simulators, three water slides, and 3 swimming pools. The ship is divided into seven neighborhoods, including Central Park and Boardwalk, like her Oasis-class sisters. Harmony of the Seas has 2,747 staterooms, of various sizes, to accommodate (at double occupancy) 5,479 guests. On 10 November 2016, the vessel was officially christened by her godmother, Miami-Dade County teacher Brittany Affolter. For the inaugural season, Harmony of the Seas offered seven-night western Mediterranean cruises originating from Barcelona and Civitavecchia. According to passengers on this cruise, construction had finished and the ship was ready to sail. The ship's maiden voyage departed from Southampton on 29 May and arrived at its summer home port of Barcelona on 5 June. During these voyages, passengers complained of ongoing construction, a lack of hot water, unopened attractions, excessive waits at restaurants, and other issues. Harmony of the Seas took two short 'preview cruises', three nights to Cherbourg and four nights to Rotterdam, after reaching port in Southampton on 17 May. Her first destination was Southampton, England, although her home port was Barcelona until 23 October 2016 when she crossed the Atlantic. After a construction time of 32 months, the ship first set sail on from the STX France docks in Saint-Nazaire, viewed by some 70,000 people. The vessel was floated out on 19 June 2015, began her first sea trials on 10 March 2016, and was delivered to Royal Caribbean on. Harmony of the Seas is named after the Harmony module on the International Space Station. The success of the first two Oasis-class ships led Royal Caribbean Cruises to order a third ship of the type in December 2012. History Harmony of the Seas as she appeared when being built at STX yards in France In length, however, Harmony of the Seas is the longest cruise ship in the world. With a gross tonnage of 226,963 GT, she is the third largest passenger ship in the world, larger than her older sisters Oasis of the Seas and Allure of the Seas, but surpassed by her newer sisters Symphony of the Seas and Wonder of the Seas. Harmony of the Seas is an Oasis-class cruise ship built by STX France at the Chantiers de l'Atlantique shipyard in Saint-Nazaire, France, for Royal Caribbean International. It will reduce every single manufacturing, maintenance, operation, staffing and energy cost factor in an unprecedented manner.Approximately 120,000 t (132,000 short tons) It is a modular, turnkey solution that can take on any farming process as part of a complete farming system. NEXAT revolution is neither an extension nor an optimisation. NEXAT’s pivotal, revolutionary approach calls the diverse range of pre-existing conventional farm machinery into question for the first time. From an economic standpoint, it marks the arrival of a new era for farm profitability. Objectively speaking, NEXAT is the world’s first company to reach market maturity with the wide span concept thanks to its use of the latest technical capabilities. Due to their lack of technical potential and limitation to individual tasks and/or crops, these optimistic attempts never really took off in the real world, even commercially. Since as far back as the 1980s, there have been numerous attempts to practice controlled traffic farming using bridging vehicles known as wide span or gantry vehicles.
