By the way, I think that the LNG tankers were built at Northrop Grumman Ship Systems-Avondale Operations, only because I know that the ship yard is in Avondale. The tankers are being used elsewhere, now.
Also, BP has made a deal with the enviro freaks to give up the main shipping route that supplies the Puget Sound in return for dropping the law suit against them for not complying with environmental requirements before building their new dock. BP, of course doesn't own any shipping companies, so this is really not theirs to give up. It would mean using much longer and more hazardous routes and cost shipping companies a lot of time, aggravation, and money. The pilots association also opposes the move, but of course BP doesn't care.
I would expect if the LNG tankers were built by Northrop Grumman, they would be listed on the web site
http://www.ss.northropgrumman.com/portfolio/shipclasses1805.html
They list every ship including overhauls. LNG is not even listed as a catagory.
If you have a link for the information that BP is going to use a longer and more hazardous route than other shippers, I would like to read it.
For your information:
Only eight shipyards in the world currently build LNG tankers: three in Japan; three in Korea; and two in Europe. However, India, China, and Poland are planning to develop LNG tanker construction capabilities in their shipyards.
