A Deep Dive into Manmade Tunnels and Caverns Underground in Singapore
- ggm 4y agoThe Oil storage thing, I am surprised they get into. Firstly, as an aside I am guessing its segmented: you don't want all your eggs in one basket. But thats a huge open void-space. Secondly, you normally fill the void in these things with CO or other oxygen poor gas to ensure its low explosion risk, but that makes it immensely hazardous to humans (this is how Noel Mostert said oil tankers avoid explosion risk in the 70s: they vent the smokestack air through the tanks, or used to. I don't know what they do now) -To get into it, they had to do a massive vent/purge surely? Thats mega-expensive. Where's all the equipment you'd expect to be down there, exploiting the access? Like facilities I have seen pictures of seem to use giant versions of the MIL spec rubberised bladders. Storage of the oil in an empty void seems like a recipe for disaster. Or tanks. I expected an underground tank-farm. Maybe it was designed for barrels? I can't think of a more unwieldy storage form.
- sohkamyung 4y agoI found this PDF file [1] that gives more information on how the Jurong Rock Caverns is set up for oil storage. Maybe it will help answer your questions.

- ggm 4y agoThanks. It has the original image, it may even be the source of it. It made it clear that yes, these cavernous spaces are designed to be the container: they are making these voids to be "full" of oil. Which invites all the gas purging and safety concerns I raised. I am totally sure the SG petro industry knows these risks and deals with them btw.
