BBC News - 12/08/10

A device thought to the largest tidal energy turbine to be built in the world is due to be unveiled in Scotland.

Developer Atlantis Resources have had the AK-1000 assembled at a facility at Evanton in Ross-shire.

It will be towed on a barge from Invergordon to a European Marine Energy Centre test site off Eday, Orkney.

Shocked It's a monster!



Standing 22.5 metres tall - the height of a five-storey building - the AK1000, which resembles an underwater turbine and will be attached to the seabed, will be able to provide enough electricity for about 1,000 homes.

And there's more...

...Waters to the west of Shetland, north of Tiree, west of Colonsay and the far side of the Western Isles have been earmarked for the development of wave power. A site to the west of Kintyre, as well as two off Islay have also been proposed for tidal schemes.

This year leases were granted to seven companies for ten wave and tidal projects in the Pentland Firth and Orkney waters. The decision was made by the Crown Estate, which owns the seabed.

The offshore renewables sector in Scotland is expected to generate thousands of jobs. By 2020, wave and tidal energy could employ 2,600, and the offshore wind sector some 20,000.

Stick a few, or even loads, in the Seven instead of an expensive and environmentally damaging barrage.

If you stuck that in the Severn estuary it would be waving in dry air for much of the day. I'd leave it north of Scotland.

Impressive. Seems a lot of infrastructure, 1,300 tones, for just 1MW. And presumably lots of maintenance?

Maintenance? How on earth, no, how in the water do you maintain a thing like that when it's at the bottom of the Cromarty Firth?

Divers? Does is rise out of the water? Off shore oil platforms need lots of maintenance. Fast flowing salt water is a harsh environment.

Depends where you put it.

They have to be much heavier than a wind turbine because the medium they are working in in is denser. They are more robust so the maintenance should be lower, one would think!

You see these turbines attached to the bottom of a tidal channel with great difficulty. I wonder why they don't suspend them from an anchored barge or ship. You could lower them to the optimum depth and raise them up to the surface for maintenance. The barge could hold crew and transformer machinery plus your maintenance materials and spare parts. It seems like a lot easier proposition so I wonder why they keep trying to bolt them to a channel bottom?

With enough tax money and subsidies you can make anything a profitable proposition. Just the legal fees alone will make some firm a tidy little sum (pun intended) which will buy some barrister a summer place and a new Beamer to wiz him and his lady friend to for weekend "work sessions".Fear not your own districts Representative is keeping an eagle eye out for this sort of thing and will make sure that no such shenanigans go on under his nose.
