During the seventeenth century the population of Kirkwall was below 1500 and it was possible for rich families to be buried in the nave of the Cathedral. The nave aisles are lined with grave stones from this period.
This is the grave stone of Captain Peter Winchester. The English inscription states that he, his wife, and their 3 children are buried there.
The grave stone is framed by the common masonic motif of ionic columns. The columns are spiralled with vines and grapes feature on the frieze. The steep pediment is dated 1675 and is flanked by birds and topped with a thistle. ( you will have to take my word for that as I chopped it off in the photo).
Couldn’t get over the Masonry, the work that must have gone into this.
Rooms leading off to room, and more great Masonry.
I had a few e-mails about yesterdays post so here is a quick follow up.
This is the vessel that we used to installed the turbine on the sea bed, its 250 ton crane had no problem lifting the turbine into place, with 3 bow thrusters and 4 stern thrusters it can hold us in position using a DP system with ease and its main engine has a bollard pull of 350 tons (anything less than 350 tons and it would just pull it along the ground).
In the sliding door you can see on the starboard side is a in-built Triton XLX work class ROV and a second one on deck. Built to meet future environmental standards, the vessel is fuel efficient and clean class, thus having the capability to work in most of the world’s offshore oil & gas precincts.
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.
