'''Orbital Marine Power Ltd''' is an [[Orkney]]-based developer of floating tidal stream turbines that have twin rotors either side of a long tubular hull. Their third-generation turbine, the 2&nbsp;MW [[Orbital O2]] has been deployed at the Fall of Warness since 2021.<ref name=":12">{{Cite web |title=Orbital Marine Power : EMEC: European Marine Energy Centre |url=https://www.emec.org.uk/about-us/our-tidal-clients/orbital-marine-power/ |access-date=2023-12-03 |language=en}}</ref> The company was founded in 2002 as Scotrenewables Tidal Power Ltd, but rebranded in 2019.<ref name=":02">{{Cite web |date=2019-04-30 |title=Orbital Marine Power going with the ebb and flow |url=https://www.heraldscotland.com/business_hq/17608237.orbital-marine-power-going-ebb-flow/ |access-date=2023-12-03 |website=The Herald |language=en}}</ref>

=== Pulse Tidal ===

'''Pulse Tidal Ltd''' was an English tidal stream developer, formed in 2007 after 10years of development, that developed an oscillating hydrofoil device. This fully-submerged device was designed to work in shallow water, and had horizontal blades which moved up and down in the passing current. A 100&nbsp;kW, prototype was installed in 2009 at [[Port of Immingham|Immingham Dock]], in the [[Humber|Humber estuary]], which could generate up to 150&nbsp;kW for a nearby chemicals plant.<ref>{{Cite web |title=Sad news for Pulse Tidal {{!}} Reuters Events {{!}} Renewables |url=https://www.reutersevents.com/renewables/tidal-today/sad-news-pulse-tidal |access-date=2024-10-06 |website=www.reutersevents.com}}</ref><ref>{{Cite web |title=News: Pulse Tidal sinks into liquidation |url=https://www.rothbiz.co.uk/2014/04/news-4061-pulse-tidal-sinks-into.html |access-date=2024-10-06}}</ref>

The company was awarded €8m in European funding to develop the first commercial prototype, expected to be rated at 1.2&nbsp;MW, and deployed at [[Lynmouth]], Devon, where Pulse Tidal had been awarded a seabed lease from the [[Crown Estate]].<ref>{{Cite web |last= |title=Pulse Tidal secures lease agreement to deploy 1.2MW power system in UK |url=https://www.powerinfotoday.com/tidal-energy/pulse-tidal-secures-lease-agreement-to-deploy-12mw-power-system-in-uk/ |access-date=2024-10-06 |website=Power Info Today |language=}}</ref> The company was also developing plans for the [[Kylerhea Narrows]] between the mainland of Scotland and [[Isle of Skye|Skye]].<ref>{{Cite news |date=2010-05-26 |title=Tidal power device for Skye a 'world-first' |url=https://www.bbc.co.uk/news/10153669 |access-date=2024-10-06 |work=BBC News |language=en-GB}}</ref>

'''Sabella SA''' is a French [[Small and medium-sized enterprises|SME]] based in [[Quimper]], Brittany that has been developing tidal turbines since 2008, however the company was placed into receivership in October 2023.<ref>{{Cite web |title=Who we are? |url=https://www.sabella.bzh/en/home/ |access-date=2023-12-22 |website=Sabella |language=en-GB}}</ref><ref>{{Cite web |last=Garanovic |first=Amir |date=2023-10-23 |title=Sabella goes into receivership |url=https://www.offshore-energy.biz/sabella-placed-in-receivership/ |access-date=2023-12-22 |website=Offshore Energy |language=en-US}}</ref> The company had developed two main variants of their technology.

The '''D03''' was a 30&nbsp;kW horizontal-axis turbine, with a six-bladed rotor 3&nbsp;m in diameter, hence the name.<ref>{{Cite web |title=D03 |url=https://www.sabella.bzh/en/our-projects/d03/ |access-date=2023-12-22 |website=Sabella |language=en-GB}}</ref> It was tested in the [[Odet]] estuary in 2008, but not grid connected. The turbine weighed 7&nbsp;tonnes, and sat on a gravity base in around 25&nbsp;m deep water.

The larger 1&nbsp;MW '''D10''' turbine was then developed, and tested in the [[Fromveur Passage]], Brittany from June 2015. After hackers interrupted the communications link with the turbine, it began supplying power to the grid in [[Ushant]] on 5 November 2015.<ref>{{Cite web |last=Poindexter |first=Gregory |date=2016-03-23 |title=Hackers rendered 1-MW Sabella D10 tidal turbine inoperable in France |url=https://www.hydroreview.com/business-finance/hackers-rendered-1-mw-sabella-d10-tidal-turbine-inoperable-in-france/ |access-date=2023-12-22 |website=Hydro Review |language=en-US}}</ref> The device was periodically removed for maintenance, for example in April 2019 after having been re-deployed in October 2018.<ref>{{Cite web |date=12 April 2019 |title=Sabella tidal device undergoes maintenance |url=https://renews.biz/52642/sabella-tidal-device-undergoes-maintenance/ |website=ReNEWS.biz}}</ref> It was redeployed for a third test campaign in April 2022,<ref>{{Cite web |last=Garanovic |first=Amir |date=2022-05-04 |title=Sabella reinstalls D10 tidal turbine for third test campaign offshore France |url=https://www.offshore-energy.biz/sabella-reinstalls-d10-tidal-turbine-for-third-test-campaign-offshore-france/ |access-date=2023-12-22 |website=Offshore Energy |language=en-US}}</ref> and in September 2023, it was reported the turbine was supplying around 25% of the electricity used on Ushant Island.<ref>{{Cite web |last=Garanovic |first=Amir |date=2023-10-10 |title=Sabella's D10 tidal turbine breaks power production record |url=https://www.offshore-energy.biz/sabellas-d10-tidal-turbine-breaks-power-production-record/ |access-date=2023-12-22 |website=Offshore Energy |language=en-US}}</ref>
