ORE Catapult have operated the turbine as an open-access platform, giving academics and researchers the opportunity to try new products in a real-world environment.
The research institute acquired the turbine from Samsung in 2015 after the South Korean manufacturer quit the offshore wind turbine manufacturing business.
More than 50 companies have benefitted from access to the turbine and the data it generates, ORE Catapult said.
Andrew Jamieson, chief executive at ORE Catapult, said: "Accessing real-world operational sites to test and demonstrate new products and services can be a real barrier to small companies looking to break into the offshore wind market.
"The Levenmouth turbine offers an easily accessible alternative to demonstrating technologies offshore in harsh and difficult to access sites.
"The turbine has been at the heart of UK offshore wind industry development for the last four years, and it will now continue to play its part for many more, providing benefits both locally and across the UK."
In August 2017, the Scottish government invested £920,000 (€1 million) to help the creation of a "digital clone" of the 7MW machine.
The clone project included installation of sensors across the turbines blades, tower and substructure.
Construction of the 7MW, 171-metre rotor turbine was completed in October 2013, and it was commissioned in early 2014.
