TRL 7/8: Open Water System Testing & Demonstration & Operation
Technology Description The AR series turbines are commercial scale Horizontal Axis Turbines designed for open ocean deployment in the harshest environments on the planet. AR turbines feature a single rotor set with highly efficient fixed pitch blades. The AR turbine is rotated as required with each tidal exchange using the on board yaw system. This is done in the slack period between tides and fixed in place for the optimal heading for the next tide. AR turbines are rated at 1MW.

Mooring Configuration Site specific design mono pylon or gravity base structure.

The AR 1000 deployed at EMEC makes use of a GBS foundation.

Optimum Marine/Riverline Conditions AR turbines are rated at 2.65 m/s of water flow velocity.

Device Testing
Scale Test •AR series turbine uses similar blade and PTO design as the AS series turbine Blades were tank tested at Southampton University before fabrication of the full scale blades was undertaken
Lab Test •Extensive blade testing including CFD and FEA prior to installation All powertrain components have been Factory Acceptance Tested FAT prior to assembly The complete turbine underwent complete System Integration Test Y SesIT before deployment subsea
Full-Scale Test •Atlantis connect its 1MW AR1000 tidal turbine to the grid at the European Marine Energy Centre EMEC in Orkney Scotland on Thursday the 11th August 2011 Atlantis Resources Corporation will continue its AR1000 tidal turbine testing programme at the National Renewable Energy Centre Narec in Blyth Northumberland The company s AR1000 nacelle was retrieved from its test berth at the European Marine Energy Centre EMEC in Orkney in late November following successful open ocean testing It will be transported to Blyth for preparation ahead of the spring opening of Narec s 3MW capacity turbine drive train testing facility The independent onshore facility has been developed to de risk in field activities conducting reliability and performance appraisals of new devices and system components through accelerated lifetime testing
