The PG&E main trunk line from Canada does indeed operate at a lower pressure than an LNG tanker. Natural gas is a mixture of various molecules and isomers. In the PG&E line some of the gas is liquefied and others are gaseous.

During the winter the gas must be fractionated before being pumped into the pipeline as some fractions can form solids at Winter temperatures plugging the pipeline at low points.

This is all very interesting, but the end result is that a failure of the PG&E pipeline is far less dangerous than an LNG tanker - since most of the product is already gaseous and lighter than air. Only a portion of the product released from a failure in the PG&E line has the more dangerous initial liquid characteristics of the product in an LNG tanker.

The liquefied nature of the LNG is what allows it to travel laterally at high speed in a wave - what the Chevron-Texaco report calls a plume.

I don't think you will find Goggle to be a reliable source of reporting for industrial accidents.

You haven't the slightest idea of what the actual results of an LNG leak would be like. It doesn't leak slowly like crude oil, which is easily contained. It pours out in a huge boiling cryogenic wave which travels at speeds dramatically faster than a flood of water from a burst dam - then it catches in fire.

The wave is initially too concentrated to ignite - not enough air mixed into the torrent. Only after the liquid wave has dispersed greatly does it contain enough oxygen to ignite.

Why not play it safe and start off small by filling your water bed with gasoline. I'd suggest working your way up to an LNG accident in small steps.
