The turbine's nacelle was installed on 18 October followed by the attachment of the three blades that provide a rotor diameter of 171 metres. The installation work was carried out by Graham Construction.
Samsung expects to start testing the prototype by the end of the year. The South Korean firm has invested £70 million (EUR 82 million) in the project and will have a 19-strong team to work on the testing programme over the next five years.
Turbine certification, which will be completed in the first half of 2014, will enable Samsung to give performance data for the machine, such as power output at variable wind speeds.
Samsung is also planning to develop a manufacturing facility in partnership with David Brown Gear Systems, and has been working with Fife Council and investment agency Scottish Enterprise.
Maggie McGinlay, Scottish Enterprise’s director of energy and clean technologies, said: "The development of the turbine in Fife is testament to Scotland’s growing reputation as a global centre of expertise for the next generation of offshore wind energy technologies."
State owner of the UK seabed, the Crown Estate, worked with Scottish Enterprise to ensure Samsung had access to the seabed.
Ronnie Quinn, Crown Estate’s energy and infrastructure lead in Scotland, said: "This marks a big step forward for offshore wind technology development, and we’re pleased to be providing ongoing support to Samsung."
