shasto100 Posted February 25, 2009 Share Posted February 25, 2009 I did a college work experience with the Fire Brigade based on Peel Road, the aerial shot of Douglas with two large damage radius overlays with the quay as the epicentre was quite scary!

Jimcalagon Posted February 25, 2009 Share Posted February 25, 2009 I've been trying to find out the equivalent in kilotons if a gas tank like those in Douglas went up... Energy security Liquefied energy gases. liquefied natural and petroleum gases (LNG and LPG) are increasingly common items of commerce. A modem marine LNG tanker contains, at -260°F, enough gas to form a flammable gas-air mixture several hundred times the volume of the Great Pyramid of Cheops. Spilled LNG boils into gas so cold that it remains heavier than air. The plume can drift along the ground for miles before it ignites in a conflagration like a hundred Hindenbergs. Radiant heat from such a fire would cause third-degree bums and start fires a mile or two away. [...] LNG is shipped by marine tanker into terminals, one of which is in Boston Harbor. Each terminal contains several LNG tanks, each equivalent in energy content to over half a megaton. The U.S. has about 50 additional LNG storage depots above ground, each equivalent to more than 130 kilotons. LNG is also delivered by trucks, each with a quarter kiloton of energy content, routinely traveling over key bridges. and through urban centers. Under suitable circumstances, one LNG truck falling off of Boston’s Southeast Expressway could fill with flammable air-gas mixture the entire Boston subway system, or the city’s major tunnels, or enough of the sewer system to blow up virtually every street in the city. LPG is shipped by marine tanker, high-pressure pipeline, ail, and ubiquitous trucks. Each LPG railcar contains energy equivalent to about three-fourths of a kiloton, releasable in a violent fuel-air explosion that can hurl large shrapnel and cause second-degree bums by radiation up to a mile away. AFAIK the Hiroshima explosion was 15 Kilotons Link to comment Share on other sites More sharing options...

Jimcalagon Posted February 25, 2009 Share Posted February 25, 2009 LNG is Bostons only ever so slightly larger than Douglas - haven't seen many super tankers docking lately. Strangely, I was aware of that fact. I was trying to find some kind of information as to the kiloton equivalent should one tank explode. In my foolishness I though that this sentence... Each terminal contains several LNG tanks, each equivalent in energy content to over half a megaton. ...might be relevant. Thanks for putting me right.

Each terminal contains several LNG tanks, each equivalent in energy content to over half a megaton. ...might be relevant. Thanks for putting me right. I see. would all that energy be released at once? had a look at Bleve, where they had a pretty big incident - http://www.metacafe.com/watch/1260604/seoul_bleve/ edit - I've not got sound here so you'll have to tell me what they say. pretty big fire ball though however it seems thats exactly what it is - a fireball as opposed to a violent explosion that you would get from a nuclear blast - no where near the same shockwave. good compaison might be - only half a kiloton of TNT compared to that gas tanker which supposedly has 62 kilotons of energy stored or around 2,600,000,000,000,000 joules.

jehovah Posted February 25, 2009 Share Posted February 25, 2009 So, if it blew up would the cliffs collapse and put the fire out? Link to comment Share on other sites More sharing options...
keyboarder Posted February 25, 2009 Share Posted February 25, 2009 Someone told me that if I was foolish enough to plumb in a gas hob whilst not being a Corgi member, it would almost certainly explode and release energy equivalent to a star collapsing in on itself after reaching the end of it's useful life. He did have a pair of underpants over his head though so it was quite hard to take him seriously. Link to comment Share on other sites More sharing options...
Jimcalagon Posted February 25, 2009 Share Posted February 25, 2009 So, if it blew up would the cliffs collapse and put the fire out? No, the cliffs would collapse and funnel the fireball down Strand Street, causing £2 million worth of improvements. Link to comment Share on other sites More sharing options...
Deejay Denzel Posted February 25, 2009 Share Posted February 25, 2009 There's no pressure there so i doubt it would even damage a pain of glass that is 200 years old sat right next to it. if there were a fire, I believe the maps at the fire station show safe distances in relation to the smoke/fumes given off depending on wind direction Link to comment Share on other sites More sharing options...
