On 27 September 2011, TUI Cruises ordered a 97,000 GT cruise ship from STX Finland Turku shipyard with delivery date set in 2014. The cost of the nearly 300-metre (980 ft) was approximately 360 million euro.[4] The contract also included an option for an identical sister vessel, which was confirmed on 5 November 2012.[5] According to TUI Cruises, the new ships would set a new environmental friendliness standard for the cruise line and feature a number of new technologies to improve the fuel efficiency.[6]
In late 2012, STX Finland was bidding for the construction of the third Oasis-class cruise ship for Royal Caribbean International in Turku shipyard and the funding of the two cruise ships for TUI Cruises was tied to this contract due to the difficult financial situation of the Finnish shipbuilder. However, after the shipyard failed to obtain a 50 million euro emergency loan from the Finnish Government and the contract for the world's largest cruise ship was awarded to STX France, there was a danger that the Turku shipyard could face bankruptcy unless it could quickly re-negotiate funding for the vessels, the first of which had been laid down on 12 December 2012 under the name "Newbuilding 1383".[1][7] By February 2013, the financial crisis appeared to be over after STX Finland was awarded 31 million euro in the form of "innovation aid" from the Finnish Government and the city of Turku purchased the land where the shipyard was located for 23.5 million euro. The South Korean parent company, STX Offshore & Shipbuilding, would also participate in the funding and the client, TUI Cruises, agreed on more flexible payments.[8] However, due to the looming liquidity crisis of STX Corporation later in the spring, the funding of the newbuildings as well as the future of the whole shipyard seemed again uncertain.[9] The crisis was finally solved when STX Finland sold its shares of Aker Arctic Technology Inc to the state-owned Finnish Industry Investment for 9.3 million euro in December 2013.[10][11]
The ship was launched on 8 November 2013 and officially christened Mein Schiff 3, German for "my ship".[12] On 22 April 2014, she left for the first and, due to the tight production schedule, only sea trials.[13]Mein Schiff 3 was handed over to TUI Cruises on 22 May 2014. She will be followed by Mein Schiff 4, delivered in 2015,[14] and slightly modified sisters Mein Schiff 5, delivered in 2016, and Mein Schiff 6, delivered in 2017.
Mein Schiff 3 overall interiors was designed by CM Design, who had previously worked on TUI Hotels; Wilson Butler Architects who designed the open decks, main theater, and the first concert hall at sea onboard;[15] Tihany Design, who designed aft of the ship featured the faceted glass structure that enclosed the Große Freiheit lounge and restaurant; and Tillberg Design of Sweden.[16] The open decks features one of the longest pools at sea(25 meters) along with a standard size covered pool aft of it.[17]
Between 16 April 2014 until 28 April 2014, Mein Schiff 3 had an additional stern thruster fitted between frames 26 and 33. The work was undertaken in dry-dock in Navantia in Cadiz Spain over nine days, with finalisation of the works during operational navigation.
