New Cargo Ship Is 488 Meters Long

An anonymous reader writes: The BBC reports on the construction of Prelude, a new ship that will be the world's longest vessel. It is 488 meters long and 74 meters wide, built with 260,000 tons of steel and displacing five times as much water as an aircraft carrier. Its purpose is to carry an entire natural gas processing plant as it sits over a series of wells 100 miles off the coast of Australia. Until now, it hasn't been practical to move gas that comes out of the wells with ships. The gas occupies too much volume, so it is generally piped to a facility on shore where it is processed and then shipped off to energy-hungry markets. But the Prelude can purify and chill the gas, turning it into a liquid and reducing its volume by a factor of 600. It will offload this liquid to smaller (but still enormous) carrier ships for transport.

    It'd be hard for it not to given that it weighs five times as much.

    The headline is wrong. This is not at all a cargo ship. It's more like an free-floating platform on which a gas refinery has been built. It will stay in place during its entire lifetime.

    It should not even be compared to ships.

      Well, is it going to go there on its own power or will it have to be towed? If it can go there by itself, then it's a ship.

      Well,technically it's a ship, I think. A quick search did not answer the question as to whether it is self powered. If it is, it's a ship (certainly not a 'cargo' ship). If it isn't it is a barge according to maritime right-of-way rules.

      It's friggin large whatever you want to call it.

      Funny, Shell is going to spent $20 BILLION or so on this thing for a 25 year lifespan (and perhaps another 25 with a whole lot of refurb). That's a lot of solar panels, insulation, wind mills and hell, even a nuclear plant or two.....

      But, if they are thinking $20 billion is worth it, you can be it is going to process a LOT more than that number in gas. My guess is they are looking at around $10 Billion/year return from their investment which gives them a 5 year payoff with operational costs. This beast will likely produce $250 Billion in revenue with about half that being profit.

      No "green energy" installation of the same price would come close to this kind of profit.

      You're numbers aren't even close:

      3.6 million tonnes a year, projected.
      http://www.bbc.com/news/scienc...

      1 million metric tons LNG = 52 trillion Btus
      http://www.extension.iastate.e...

      3.6 * 52 trillion
      that's about 175 trillion BTUs.

      Current price ~10 dollars per million BTU.

      1.75 Billion a year, BEFORE cost of operation.

      Which is a very odd claim - since you produce no numbers whatsoever for "green" energy.

      And you forget that natural gas isn't just a source of BTU's - it's also a major feedstock for a variety of industrial processes. (A significant portion of "oil derived" plastics are actually derived from natural gas.)
