"Typically when wells run dry, rigs are dismantled, but Emily Callahan and Amber Jackson argue that more retired oil infrastructure should remain in place permanently, as habitat. Jackson and Callahan met while studying at the Scripps Institution of Oceanography and went on to co-found the firm Blue Latitudes, which has consulted on several rigs-to-reefs projects around the world. "These structures are already in the environment. Why get rid of this amazing ecosystem that's already there?" Jackson says.

This view is controversial. Greenpeace, for example, has argued that rigs-to-reef projects subsidize the fossil fuel industry by reducing costs to dismantle drilling platforms. Environmental groups are also concerned that toxic debris may remain in the ocean and that rigs encourage overfishing.
Jackson and Callahan also explore habitats created by these artificial reefs and recently released a short documentary about a retired rig off the island of Borneo that is now an eco-resort. At the hotel, guests stay on the deck and dive on the reef beneath. It's the first project of its kind, Callahan said, and an example of creative thinking about how to reuse rigs."
