If you really want to ferry it out to this part of the world tanking it up and going via the USA would be by far the easiest way from a political and bureaucratic point of view. Technically a bit harder with the tanking requirements.
Putting it in a box will be the easiest way to get it here.
The best option over all is to sell it in the UK and buy out here, though I guess you have your own reasons for wanting to keep it.
