Singapore digs deep to be petro hub

One hundred and thirty metres below the sea bed of Singapore lies a most unusual construction site. Hundred of workers are carving out a series of enormous caverns in hard rock. The work is laborious, expensive and will take years to complete, but eventually they hope to create a space large enough to store the equivalent of nine million barrels of oil. Why? Because Singapore, all 700 sq km of it, is running out of room. The company behind the project, state-run Jurong Town Corporation, wants to provide a secure storage site for companies that will pay them for using the space.
