and electrical system, generator and turbine. Rudders mounted at the end of the nacelle enable the device to move in its pre-determined trajectory, and struts and a top joint connect the wing with the tether. Edlund says that, “Te tether then connects to a bottom joint that is on top of the seabed foundation – in our current installation in Wales, a gravity-based concrete structure. Te tether is a unique feature and is specific to the Deep Green system, however it is made up by relatively standard components such as Dyneema fibre, electrical cables and polyurethane fairings. Each of these components are tailored to the application to match factors such as power rating, length, forces and lifetime, which is quite normal for any project.” Edlund reveals that some of the internal components are off-the-shelf, “such as sensors, cables, inverters and connectors, whilst the external components including wing, turbine, nacelle body, struts and rudders are designed specifically for the Deep Green system.” Other components are adaptions of existing products to Minesto’s application, such as the
