Gulf Coast Oil Platforms: Save the Rigs?
Gulf Coast Oil Platforms: Save the Rigs?
A federal program urges the fast removal of “idle iron” oil and gas platforms in the Gulf of Mexico. But in an unexpected twist, some environmentalists want the rigs to remain as a home for fish.
This year, it’s likely more than 100 offshore structures in the Gulf of Mexico will be removed as part of a Department of the Interior plan. There are 650 nonproducing oil and gas platforms, known in the industry as “idle iron,” listed for removal “as soon as possible”—i.e. within five years of the end of production or a year of losing the lease—under Interior’s directive. Historically, companies seldom removed an idle structure until the lease for the area where it was located expired.
Having companies clean up after themselves sounds like a good idea, but many recreational fishermen, scuba divers, scientists, and fishery managers aren’t happy about it. Turns out, some of the 2,500 multileg platforms that pepper the Gulf of Mexico have become de facto artificial reefs. According to Bob Shipp, University of South Alabama’s Department of Marine Sciences, the platforms have transformed the entire ecosystem. Some marine species are attracted to platforms for shelter or food, but others—sea fans, sponges, algae, and reef fish—spend their entire life cycle on these structures. What’s more, some species have increased in number because of the platforms.
