Three Andritz Hydro Hammerfest '''AH1000 MK1''' turbines were installed as part of phase 1 of the [[MeyGen]] project in 2016. These turbines are still three-bladed, but with an 18&nbsp;m diameter rotor and each rated at 1.5&nbsp;MW.<ref>{{Cite web |title=MeyGen |url=http://saerenewables.com/tidal-stream/meygen/ |access-date=2023-12-21 |website=SAE Renewables |language=en-GB}}</ref>

=== Flumill ===

'''Flumill AS''' is a Norwegian developer of an unconventional tidal stream turbine. It consists of two counter-rotating helical screws made from [[fiberglass]], each attached to a gear-less permanent magnet generator.<ref name=":33">{{Cite web |last=Snieckus |first=Darius |date=2011-11-23 |title=In Depth: Turning a twin-corkscrew turbine into 'beautiful' reality |url=https://www.rechargenews.com/wave-tidal-hydro/in-depth-turning-a-twin-corkscrew-turbine-into-beautiful-reality/1-1-841450 |url-access=subscription |access-date=2024-01-20 |website=Recharge |place=Bristol |language=en}}</ref> The unit is mounted to the seabed and held up by a buoyant float/fin.<ref>{{Cite web |last=London Research International |date=August 2013 |title=Technology Feature: The Flumill |url=https://londonresearchinternational.com/wp-content/uploads/2021/05/2013.8_The-Flumill.pdf |website=GreenTechEurope.com Newsletter}}</ref> In 2011 Flumill was the first turbine to be tested at the EMEC [[European Marine Energy Centre#Non-grid connected test sites|Shapinsay Sound]] non-grid-connected test site, after tow tests in Tromøysund, [[Arendal]], Norway.<ref>{{Cite web |title=Our Tidal Clients: Flumill |url=https://www.emec.org.uk/about-us/our-tidal-clients/flumill/ |access-date=2024-01-20 |website=European Marine Energy Centre |language=en}}</ref><ref>{{Citation |title=Flumill |date=7 Nov 2012 |url=https://www.youtube.com/watch?v=8PEiWgvDUSI |access-date=2024-01-20 |publisher=YouTube |language=en}}</ref> This device was nominally rated at 1.2&nbsp;kW in the 1.5&nbsp;m/s currents of Shapinsay Sound, although it could potentially generate 600&nbsp;kW in faster flows.<ref name=":33" />

A phase 2 Flumill tidal device is currently being developed, where the screws and generators are mounted from a catamaran barge.<ref>{{Cite web |title=Aquatera Ltd on LinkedIn: This month, Aquatera had yet another successful All-Energy Exhibition and… |url=https://www.linkedin.com/posts/aquatera-limited_this-month-aquatera-had-yet-another-successful-activity-7066746984061116417-rsnE |access-date=2024-01-20 |website=www.linkedin.com |language=en}}</ref>
