SR2000 installation October 2016

Orbital Marine Power launched the full commercial scale SR2000 2MW, the world’s most powerful tidal turbine, at the European Marine Energy Centre in 2016.

Designed to DNV-GL standards with a 20 year design life, the SR2000 incorporates proven, commercialised components from other industries to the market enabling Orbital superstructure.

The large scale turbine can be installed in water depths of more than 25 metres due to the flexible mooring system and can be deployed with a range of anchoring systems to suit most seabed types.

In October 2016, the SR2000 was successfully installed at the European Marine Energy Centre (EMEC), a 5x ROC-accredited marine energy converter test site in Orkney, making history as the largest and most powerful tidal energy converter in the world. 

All installation and maintenance operations during this test programme has been delivered with low cost, locally based vessels proving the company's simplified commissioning and maintenance strategies at full scale. 

Up until the project’s completion in September 2018, the SR2000 produced excellent performance results and has delivered several world-firsts, including demonstrating a load factor in excess of 38% in its first 24 hours of continuous generation and generating over 120 MWh in 7 days of generation with load factors in excess of 35%. During this period, the single 2MW device also generated circa 7% of the Orkney Islands electricity demand, with shorter periods exceeding 25% of demand.  Over its test programme, the SR2000 produced over 3,000 MWh of electricity.
