Retired oil rigs off the California coast could find new lives as artificial reefs

Source: theconversation.com

Offshore oil and gas drilling has been a contentious issue in California for 50 years, ever since a rig ruptured and spilled 80,000 to 100,000 barrels of crude oil off Santa Barbara in 1969. Today it’s spurring a new debate: whether to completely dismantle 27 oil and gas platforms scattered along the southern California coast as they end their working lives, or convert the underwater sections into permanent artificial reefs for marine life.

We know that here and elsewhere, many thousands of fishes and millions of invertebrates use offshore rigs as marine habitat. Working with state fisheries agencies, energy companies have converted decommissioned oil and gas platforms into manmade reefs in the U.S. Gulf of Mexico, Brunei and Malaysia.

Californians prize their spectacular coastline, and there are disagreements over the rigs-to-reefs concept. Some conservation groups assert that abandoned oil rigs could release toxic chemicals into the water and create underwater hazards. In contrast, supporters say the submerged sections have become productive reefs that should be left in place. MORE
