Pipelines for water are only energy efficient if you have gravity working for you. I'm willing to wager that there isn't a 10x difference in the cost of towing that water to the Barbados versus pumping it in a pipeline. And, of course, you don't need a pipeline when you tow it. (though you do need big bags)
