Dobby_The_Ship_Elf Posted February 9, 2017 #5 Share Posted February 9, 2017 I was trying to think where a ship would use a gas bottle. Obviously not for cooking like we do for our BBQs in the backyard. I wonder if the gas bottle was fitted to one of the fork lifts in the stores area. If so, these are generally 15 kg LPG bottles. As a techo with lots of fire experience in my day to day life I know certain things such as .... LPG is actually a gas compressed and transported a fluid, when it is released it forms back into a gas ie BBQ gas. 1L of LPG (propane) weighs 0.51kg. Considering 1L of liquid LPG (propane) equals 270L of gaseous LPG the 15 L gas bottle would have had 7.5 L of liquid. That means 7.5 L of liquid is actually 2025 L of gas or thereabouts. That's a lot of fuel and in a confined space like under decks of a cruise ship one can only imagine the size of the fire. However this was reported as an explosion. An LPG explosion is a rare event. An explosion is all that energy being released at once. The only place to be to witness one of these is in the front bar of the pub watching the news!! On a related note - that is why you should always do a leak check whenever you change your BBQ gas bottle. A 'sniff check' or 'hiss test' just doesn't cut it as an answer to your wife & kids when the flames are burning down your house.

sailco Posted February 9, 2017 #7 Share Posted February 9, 2017 There's a photo of the bottle lying on the wharf at http://www.stuff.co.nz/national/89259548/emergency-services-rush-to-port-chalmers-after-explosion-on-cruise-ship It looks like one of the bottles we have at home for our cooking & heating. I hope there are not too many people injured. Link to comment Share on other sites More sharing options...

Dobby_The_Ship_Elf Posted February 9, 2017 #12 Share Posted February 9, 2017 Welding, maybe? Nope - you don't weld with LPG. Well done. You have nailed it this is an oxy-acetylene weld issue cos that is what the cylinder looks like to me from this image. Acetylene cylinders are red/maroon this cylinder is industrial oxygen used in welding to provide the ooomph. For it to end up on the dock shows how lucky it was for it not to happen at sea Link to comment Share on other sites More sharing options...
Rare OzKiwiJJ Posted February 9, 2017 #13 Share Posted February 9, 2017 It was the only thing I could think of where they would be likely to have a gas bottle of some sort on deck, and there had been no actual confirmation of what type of cylinder it was as far as I know, only speculation.

rkmw Posted February 9, 2017 #14 Share Posted February 9, 2017 This was posted by a passenger on the Emerald Just a quick update on our situation. The maritime union have to investigate and can't get here until 10am tomorrow. This means we will miss The Fjordlands and will sail directly for sydney when we are able. I have no idea what that will mean for our arrival time in Sydney given we won't be leaving Port Chalmers for at least 16 hours after the anticipated departure time.

Icerecon Posted February 9, 2017 #15 Share Posted February 9, 2017 A sad Accident and my thoughts go to the Crewmans family. Both sotries by the links provided state the it was a nitrogen cylinder, which I believe is used to compress the hydraulic accumulator attached to the life boat systems which I guess was being tested, topped up, replaced but we will have to wait until the investigation has been completed.

Here endeth your Elfie lesson The Herald understands inflatable vessels were being reinflated on deck seven when a 45kg gas cylinder exploded and flew through the air, killing the crew member. The gas bottle was then seen spinning on the wharf with its base blown out, according to a passenger on board. Not LPG but more likely to be Nitrogen or oxygen, both can be very dangerous as well. They were lucky it didn't do more damage. Very sad for the crew member and his family and colleagues. Link to comment Share on other sites More sharing options...

hematocrit Posted February 10, 2017 #19 Share Posted February 10, 2017 Passengers are being allowed to leave ship and shuttle busses laid on to Dunedin. "All on Board" by 5pm, so we won't be leaving before 6pm at earliest (24 hours late) then sailing direct to Sydney - so missing out on the Sounds! All very sad on board at the tragic death.

I certainly wouldn't want to be around if one of them let loose. Talk about a loose cannon(ball) wowee I spent some time in the early hours on my walks talking in broken 'technical English' to some of these guys on the Emerald, most were either Filipino or Indonesian, once I did they always smiled, waved and spoke to me every day - nice guys that worked really hard and long hours. I fear it was one of these blokes, very sad Link to comment Share on other sites More sharing options...

Kiwi Kruzer Posted February 10, 2017 #23 Share Posted February 10, 2017 On the albatross webcam the ship can still be seen in port. The cruise schedule is now showing departure at 21.00. Wonder if they will keep to that.. At least the wind has dropped from last night. Link to comment Share on other sites More sharing options...
