His capacity concerns in the near term was not on the shipping capacity, but rather in the liquification facilities.  In a few years though, shipping capacity will be tight.

As for ship capacities, the average is 3.3BCF with capacities as large as 4.5 out there.  His expectation was that as time goes one, ship capacity would also increase, somewhat reducing the overall number.  

When it comes to servicing NA, its clear that most deliveries would not originate from the ME.  Sempra (the only one with a terminal underconstruction) signed a contract with an indonesian supplier (for only half of the terminals rated capacity though).  Logic would dictate that most sources would be closer, namely 20-25 day sail, not 40.  Alaska LNG would be the fastest, as would bolivia for any new West Coast location.  East coast locations would probably continue to source from existing locations, plus any incremental additions from W. Africa.

My real question on the future of LNG really has to deal with how much GTL production could impinge on LNG production.  Given the inevitable shortage in Liquid fuels and the attendant rise in prices, how much gas will get Haber-Bosched into diesel and sold to China in a simple tanker ship rather than chilled and liquified and sent via LNG ship to the US.

I am not sure if anyone has looked at the play between these two end uses for methane.
