Great info Dave!

Question: how much BCF can be on one tanker, and if there was a problem, what is the size that that gas would expand to? In other words, how big is a billion cubic feet of gas in the air? I assume 1 billion cubic feet is 1000x1000x1000 so is a cube the size of three lengths of football fields on each side (per bcf)

When the gas industry says cf of gas they usually mean standard cubic feet, which is at 60 deg F and 14.696 psia.  So a billion standard cubic feet of gas at normal ambients occupies close to a billion cubic feet of actual volume (or water volume).

Largest LNG tanker now holds 'bout 145K m3 of tank vol => 3 BSCF (billion standard cubic feet)

probably increasing in future to 200K m3 of tank vol => 4 BSCF

Tanks are thinner towards the top and looks like future tankers will be using aluminum tanks to save weight.

Sandia Labs study classifies a successful terrorist attack on an LNG tanker as a, "Low probability, high consequence  event." Radiated heat would be damaging within a 1 mile radius.
