No not my Mum! this thing. Anyone guess what it is before I tell you? No it’s not a(insert your guess here). It is actually an undersea turbine that we installed just off the Island of Eday which is part of the Orkney Islands.
The idea is when the tide goes out it turns one blade and when the tide comes in….you got it, yeah it turns the other end generating electricity.
Now this wasn’t the first attempt at this, Rolls Royce built one and tried to install it in the same place, that one is still sitting on the dockside after a number of years, another company tried and failed miserably. The thing is, the tide is so strong, it has to be for this thing to work which of course makes it a challenge to put it on the seabed, you need a very powerful boat with a crane and two ROV’s and you still can only do the job between the tides, thats about two hours max. So after installing the base and counter weights(not pictured) in the exact position and heading it was time for the top, this went as smooth as the rest and the job was complete in just 7 days, that’s 14 ebb tides and that’s a record.
