The Brent Delta is but one of 40 platforms between the Shetlands and Norway which reap this black liquid harvest. It is a strange and eerie world: the night sky glows bright orange; men work on deck sweltering in tropical warmth, but surrounded by a sub-Arctic sea; 300 miles from any city, commuters shuttle daily to and from their work on flying buses. Yet every activity of every one of the thousands of men confined to this unreal and dreamlike world is directed to one end alone: profit.
