World's largest mobile offshore platform, San Francisco, 1958
Photograph. "San Francisco, Dec. 15 -- Tight squeeze -- Seemingly towering high above the deck of the Golden Gate Bridge, this ungainly barge with towering legs proceeds on its way towards the open sea. The craft, a 4,500-ton offshore mobile platform, said to be the world's largest, had to lower its 270-foot towers 57 feet to squeeze under the bridge. The towers, which will eventually serve as legs reaching to the ocean floor, were raised again after passing the bridge to avoid grounding on the shallows before reaching the ocean. Barge will be used first in laying sewer pipe off Los Angeles and later in offshore oil drilling." -- caption by foot of photograph.
