SR250 Generating at full power October 2013

In 2010 following the success of the 1/5th scale-testing programme, the company designed and launched the SR250 250 kW, the world’s first large scale, grid connected, floating tidal turbine. The 35m turbine was launched in early 2011 for testing at the European Marine Energy Centre, Orkney.

The SR250 had a 2-year test programme, building up from initial handling trials, through to tow testing, to regular onsite generation.

In April 2013, the SR250 became only the second device to undergo EMEC Performance Assessment during a continuous deployment period of six weeks, independently validating the turbines power curve in varying tidal and wave conditions.

In over 4000 hours of turbine operation, there were no major failures of any structural or electrical components, blades or mooring system, and no HSE incidents since testing commenced. The ability to maintain the turbine onsite using low cost vessels was also regularly demonstrated.

At the end of 2013, the testing programme was brought to a close to focus on the build of the SR2000.
