I and a friend have been fascinated by the remains of an old oil refinery built in the 1970s by the company Occidental, but had to remove most of the structures in 1978 when protest got too high. We've been to this location a number of times, and it is a massive network of old roads. Most of the remains are just concrete, although there are other structures. One is a mile-long metal jetty designed to get oil from ships to the mainland. There was also a massive chimney until 1997, which was knocked down by Fred Dibnah himself. The concrete remains are usually stockpiles although include building foundations and and piping containers e.t.c.
Here are more detailed reports and pics on the refinery (in 3 parts) and jetty:
