Just one cruise missile...

  2. No, the Tankerman just needs to close one valve and thermal expansion will do the rest....that's why he gets the big duckets

  3. What the hell is that, a floating refinery?

    1. LFG tanker Liquefied Flammable gas

    2. I bet everyone of the crew members on that ship can thread a sewing machine while it's running by the end of that trip.

    3. LNG tanker: Liquified Natural Gas. The spheres are essentially big thermos bottles, loaded with liquified methane at -184°F. The newer ships have square tanks, an advance in technology. Gas evolves from the liquid at a reasonably slow rate and is either vented or (in more advanced ships) used as ship fuel, to keep the pressure in the tanks within spec.

      The ship transits to its market usually in about 1-3 weeks depending upon distance, and at the other end the LNG goes through controlled re-gassification and is fed into the regional pipeline.

    4. Aggie is right on the specific product, but the endorsement falls under

      CFR 188.10-43 Liquefied flammable gas.
      This term means any flammable gas having a Reid vapor pressure exceeding 40 p.s.i. which has been liquefied.

      This would include LNG

      However the specific Tankerman endorsement is LFG. In other words an A or B grade Tankerman needs an LFG endorsement to handle LNG and other liquefied flammable gases, and an LPG endorsement to tank petroleum derived gases.

    5. back in the mid 1970s when this was"new tech" the Harbor commission of NYC put out a paper defining what the results would be for a terrorist attack with a LFG tanker would mean for Manhattan and Long Island. They did dress the report up as a "potential for accident investigation exercise". So of course, they totally ignored any results for NJ coast and harbors in their analysis.
      As a fuel/air bomb, it would best be described as a 20~35kt nuke ground burst without the resultant radiation, dependent on the mixing of the gas with atmospheric O2 prior to ignition. Upon release of the LFG, it would initially look like a fog bank moving into long island and then bobs your uncle.As with most fuel/air bombs, the blast is much worse than the thermal flash.
      As for NJ coastal residents, as goes NYC, so goes NJ.

  4. it only takes a spark, to get a fire going....

    1. True but it won't be a fire, it will be an explosion and that spark can come from a tool dropping to the deck or keying up a non-intrinsically safe radio or flashlight.

      Which is why vessels like this generally have a concrete layer on the deck, while the crew uses special non-sparking tools and ground cables along with intrinsically safe communications and lighting.

  5. The fueling docks are set offshore to mitigate the boom factor, should it happen

  6. The New York Fire Department has the same plans for dealing with an LNG terminal explosion, as for a nuclear strike.

  7. A Canadian company wanted to build an LNG export terminal in Coos Bay OR (on a sand spit in an earthquake zone!), and a 220 mile pipeline to Eastern OR to connect with the national pipeline grid. Thankfully it fell through.

  8. Cruise missile, hell!

    One soda-can sized thermite bomb, dropped or set down by a COTS drone, and you can say goodbye to anything aboveground within about 9 sq. miles.
