SIMEC Atlantis Energy products

The SeaGen S system consists of twin power trains mounted on a crossbeam. The cross beam can be raised above the water for routine maintenance by winching it up the monopole support structure. SeaGen S is suitable for marine environments in water depths up to 38m and achieves rated power in tidal currents of greater than 2.4m/s. The 1.2MW system installed in Strangford Lough, Northern Ireland, in 2008 has been subject to 4 years of extensive testing.

Atlantis and GE have already been working in partnership since September 2018 on the development and performance validation of Atlantis’ AR2000 tidal generation system, which is expected to be the world’s largest and most powerful single axis turbine available. This record-breaking system is expected to be deployed on future phases of Atlantis’ iconic MeyGen Project in Scotland, the wider Atlantis project pipeline and will also be available for sale to commercial developers. This next generation turbine will be capable of accommodating rotor diameters of between 20 – 24 meters, site dependent, with a cut in speed of less than one meter per second and a maximum output of 2.0 MW at 3.05 m/s for a machine with a 20 meter rotor diameter.

The AR1500 is a Lockheed Martin designed, 1.5MW horizontal axis turbine complete with active pitch and yaw capability. The nacelle weighs approximately 150 tonnes in air and has a design life of 25 years. The rotor diameter is 18 meters and all key operational systems have triple redundancy built in to maximise reliability offshore.

SeaGen U is a 1.5MW horizontal axis turbine complete with an active pitch system taken from the SeaGen-S series development, and yaw capability from the AR1500. The full turbine weighs approximately 150 tonnes in air and has a design life of 25 years. The rotor diameter is 20 meters and all key operational systems have redundancy built in to maximise reliability offshore.

The SeaGen system designed for floating or surface piercing foundations is an up to 1.0MW horizontal axis turbine complete with an active pitch. The full turbine weighs approximately 100 tonnes in air and has a design life of 25 years. Rotor diameter can be provided to suit the deployment and system redundancy plus accessibility combine to maximise reliability offshore.

Tidal stream energy presents one of the most exciting emerging forms of renewable energy. Tidal streams, unlike many other forms of renewable energy, are a consistent source of kinetic energy caused by regular tidal cycles influenced by the phases of the moon.  Intermittency is a problem for wind, wave and solar power as the sun doesn’t always shine and the wind doesn’t always blow.  These sources of renewable energy often require backup from traditional forms of power generation. However, the inherent predictability of tidal power is highly attractive for grid management, removing the need for backup power from back-up plant powered by fossil fuels.  Tidal turbines are installed on the seabed at locations with high tidal current velocities, or strong continuous ocean currents and extract energy from the flowing water.

Consultation before Applying for Planning Permission: Town and Country Planning (Development Management Procedure) (Wales) Order 2012 as amended by The Planning Applications (Temporary Modifications and Disapplication) (Wales) (Coronavirus) Order 2020. The Uskmouth Power Station Conversion Project (referred to as the Uskmouth Conversion Project) proposes to convert the existing coal fired power plant at Uskmouth Power Station to operate as a plant which would generate electricity through the combustion of waste derived fuel pellets.

Tidal turbines are very much like underwater windmills except the rotors are driven by consistent, fast-moving currents.  The submerged rotors harness the power of the marine currents to drive generators, which in turn produce electricity. Water is 832 times denser than air and consequently tidal turbine rotors are much smaller than wind turbine rotors and therefore can be deployed much closer together and still generate equivalent amounts of electricity.
