Comment posted Quarrying at Glensanda: aggregating aggregates by Murdoch MacKenzie.
I suppose it depends on the imagination being stretched. Some only see natural beauty while others see beauty in man’s industrial efforts to improve his lifestyle.
To live the lives we desire we sometimes need to move mountains, cut down trees and extract energy. It’s what we do to make good the impact and generate re-growth that is important.
The owners and the staff at Glensanda seem to consider the environmental impact of their every action and look to have it in mind at every stage. Vegetation is evident on the “benches” left from the earlier works.
Fifty years ago when there was a lot of road building, there were small quarries dotted along the roadsides. Today most of these are hardly noticable due to government spending on tidying up schemes, modern machinery and the healing efforts of Mother Nature.
We can look at the ground around Glensanda and see evidence of the toil of the people who lived there before the Clearances. In the future other generations will see evidence of the toil of today’s people.

- The ship loader is actually on the jetty. It is a very interesting piece of equipment, more elaborate than I had imagined. From what I could see and from what I gleaned from the quarry staff I will try and explain how it works, but I did not get to see how the conveyor collects the stone or how the belt deals with it’s outward travel.
If you look at the two pictures in this article you will see that it’s base is a massive bridge structure that sits on a turntable/pivot at one end and travels in an arc on rails set into the jetty at the outer end, where you can see a driver’s cab is attached. The conveyor to the ship is set in a boom that travels outwards on top of this bridge. It looks like the back end is held down by rollers that will be below the bridge. The boom conveyor can reach the furthest away corner of any of the ships holds.

- NOW – 21.00: BBC 2′s ‘Town’ with Nicholas Crane visits Oban
Such opportunities lost, indeed. A programme about a railhead and steamer pier town that did well out of it’s extended population spread in the islands served, and from its immediate suroundings.
Today, it continues in the same role except that the steamers are now also car ferries and freight haulage ferries.
These freight ferries carry only RoRo cargoes that are so expensive that anyone in the islands who orders goods from the mainland now pays a premium haulage charge that is often greater than the value of the item.
Inverness is another town, now city, that has done well out of this stranglehold it has on the people of Lewis through their RoRo link with Ullapool.
When Is Transport Scotland going to apply to have the west coast of Scotland included in the Motorways of the Sea project so that economical shipping routes can be established between the Mersey, Dublin, the Clyde and the Western Isles?

Did he drag his anchor, it looks like it’s deployed and he’s also got an anchor ball shape up? - First Minister’s choice not to condemn mob behaviour proves Farage point
Davy MacMillan, the Scottish people will decide on everything they want to happen and if they want to be represented at the EU or not. It will not be like the papers and the politicians tell you now. If the world needs to meet renewables targets, Scotland is in a position to help countries achieve that. - First Minister’s choice not to condemn mob behaviour proves Farage point
To Malcolm and Donald above, Scotland will be bankrupt if it remains in this Union. The extra wind turbines are not for Scottish consumers but for all these countries that cannot meet the renewables threshold in their own countries, they will buy the energy from Scotland, paying the going rate including the “sudsidy” to the Scottish generators.
The power will be fed into interconnectors or it may be that a credits system can be established where it is not possible or feasible to install a connector. In that case we would burn off a higher percentage of our renewables at home than required and sell them the credit.

My understanding is that the ship’s conveyor boom is only used when discharging. At that time, the cargo is dropped through the hopper doors in the bottom of the holds, onto longitudinal conveyors which take the cargo to the foot of the vertical conveyor (in the un-lovely tower attached to the front of the superstructure). The vertical conveyor then dumps the cargo onto the start of the ship’s discharge conveyor belt, carried in the boom which is swung from the ship above the quay at Amsterdam, or Hamburg, or wherever.
My understanding is that, when loading, the quarry’s own conveyer boom carries the stone chips right above the top of the hold, so that gravity does all of the rest (until the destination port), and the ship’s conveyor boom is simply swung out of the way.
If the ship’s conveyor belt carried the new cargo on-board, you would then need some horizontal conveyors at deck level to get the cargo from the inboard end of that conveyor to the tops of the holds. That would seem to be a bigger change than has been implemented in this rebuild.

Am I glad you were there, Murdoch – apart from the pleasure of actually meeting.

Would make a good set for the next James Bond movie, but ideally the baddies would disappear into the mincing machine and that would be best achieved as the ship is unloaded and the cargo sinks into the hoppers at the base of the hold.

I have no objection to the Glensanda operation whatsoever but . . .
let no one tell you that heavy industry does not do cute
compellingly beautiful symmetrical heap of silver crushed stone
the very specific beauty that is part of industry
Am I the only one who finds this eulogy to the industrialisation and total destruction of a huge swathe of countryside a bit odd after the vitriol recently poured on the wind industry?

Surely the difference with the wind industry is that it’s creeping over the surface of the country – and the surrounding seas – like some contagion that risks getting out of control, whereas Glensanda is an admittedly very large scale operation but in a carefully chosen area of a landscape big enough to contain it. Yes, it can be surprisingly visible – for example from the road through Glen Nant, 20 miles away – but it’s surely not the ‘total destruction of a huge swathe of countryside’, and it does have a certain grandeur in its sheer scale.

Digging a mountain away in an operation like that is pretty close to total destruction, is it not?
It may be necessary, it may be in the most appropriate place and it may be very clever technically, but Glensanda is not ‘beautiful’ by any stretch of the imagination.
