The Baldpate Compliant Tower owned by the Amerada Hess Corporation is an oil and gas platform in the Gulf of Mexico, which stands 579 m (1902 feet) above the ocean floor. This structure is partially supported by buoyancy. Depending on the criteria is may be the World's tallest structure.
In practice, these larger platforms are assisted by smaller ESVs (emergency support vessels) like the British Iolair that are summoned when something has gone wrong, e.g. a search and rescue operation is required.
