Tidal energy turbine with Lockheed Martin technology deployed
15 March 2017
Atlantis Resources Limited has deployed the first AR1500 tidal energy turbine with new Lockheed Martin technology off the coast of Scotland.
The installation is the latest development in the MeyGen project designed to harness the motion of the tides to provide clean, sustainable, predictable power for up to 175,000 homes in Scotland.
Under contract and in partnership with Atlantis, Lockheed Martin designed the 1.5MW AR1500 turbine. In addition to system design, Lockheed Martin developed, manufactured and delivered two innovative subsystems, the Yaw Drive System (YDS) and the Variable Pitch System (VPS). The two elements enable the turbine to autonomously rotate around its base to face into the tidal flow and adjust the pitch angle of the turbine blades to optimise the power generation in each tidal stream.
This is the first time a tidal turbine has been installed and connected to the shore instantaneously. Installation and connection of the AR1500 was completed with record breaking efficiency in less than 60 minutes, representing a significant time reduction compared to most similar systems.
The MeyGen project is currently the largest planned tidal energy project in the world. The site in the Pentland Firth just 2km from Scotland’s north-east tip, covers some of the fastest flowing waters in the United Kingdom. Atlantis has a goal to deploy nearly 270 turbines to generate about 400MW of energy, enough to power 175,000 homes.
“Tidal turbines must be highly reliable and resilient to withstand and operate within the tough environment of a sea floor,” said Frank Armijo, vice president of Lockheed Martin Energy. “These design requirements are similar to the reliability and durability needs of many of our aerospace programs. With innovations in advanced manufacturing and materials, and our experiences in the design and production of undersea systems, space programs and aeronautics, we’re now helping to make tidal energy more reliable and effective.”
Tidal energy is produced by the surge of ocean water during the rise and fall of tides. Submerged rotors harness the power of the ocean currents to drive generators to produce electricity.
In 2013, Lockheed Martin and Atlantis entered into a teaming partnership to develop technology, components and projects in the tidal power sector on a global basis, beginning with the AR1500.
