It looked, Peter Crane thought, like a stork: a huge white stork, rising out of the ocean on ridiculously delicate legs. But as the helicopter drew closer and the outline sharpened against the sea horizon, this resemblance gradually fell away.

The central body became a multilevel superstructure, studded with flare stacks and turbines, festooned with spars and girders. And the thin, necklike object above resolved into a complex crane-and-derrick assembly, rising several hundred feet above the superstructure.
