This Is My Glasgow

Upper scuttle valve cover in the gate of the number two Govan Graving Dock, Glasgow.

You can tell that this houses the upper scuttle valve because it says so right on the cover. It also tells you what the open and closed positions for the valve are.

Knowing what an upper scuttle valve does, and when you should be opening or closing it, is quite a different matter!

@thisismyglasgow I’m guessing that scuttling a (dry) dock is the same as scuttling a ship: you’re opening a valve and letting the water in?!
Something more frequent in a dock than a ship you’d hope ;-)

@AeonMach Lol! That is my assumption too. There's both an upper and a lower scuttle valve in the gate, which I'm presuming fill up the dock to different levels.

I'm not too sure if the same valves would be used to empty the dock, when the tide goes out (the drop can be up to 4 metres between low and high tide at this point), but I'm presuming some physical pumping would have been required to remove all the water.
