Ok, not really a "piece" or even a "ship," but that title's a little catchier than "world's largest FLNG facility under construction."
I was reading through a trade magazine at work this morning and came across an article stating the first steel has recently been cut on Shell's Prelude
project, which will be the largest sea-going structure ever produced. What particularly impressed me was this:
Shell's Projects & Technology Director Matthias Bichsel commented: "We are cutting 7.6 tonnes of steel for the Prelude floating liquefied natural gas facility, but in total, more than 260,000 tonnes of steel will be fabricated and assembled for the facility. That's around five times the amount of steel used to build the Sydney Harbor Bridge.
When completed this structure will be just a shade over 1600 ft long (488m) and 243 ft wide (74m) and will come in weighing a bit over 600,000 long tons (672k US tons).
I'm a nerd for this kind of stuff, and know there's plenty of nerds here, so thought some of you might find this interesting.
