There are some good articles on Sylvia Tervoort, the Smit salvage master in charge of getting the oil platform re-floated and off the rocks. [1] She's been salvage master on about 36 big jobs. There are only a few companies in the world that take on such jobs, and since Titan and Mammoet dropped out of the business, Smit is the leader. They're noted for working safely and carefully, being extremely expensive, and getting the job done without making things worse.
