Two Innovative and Sustainable Ways to Repurpose Offshore Rigs

Offshore rigs are structures as large as skyscrapers living in the ocean. After their purpose is over, what can you do with them? Well, as they aren’t the most subtle of creatures, they need to be repurposed in some ingenious and strange ways.
Here are two innovative and sustainable ways to repurpose offshore oil rigs.
1. Repurpose oil rigs to tap into aquifers

Aquifers are pretty amazing. They are sources of freshwater that happen to be hiding under the ocean. An easy way to tap into some aquifers could be by using oil rigs. According to, oil rigs currently drill into aquifers while exploring for oil or gas, ruining the water quality, or even use them as a place to dispose of drilling waste like carbon dioxide.
As there are only 2 ways to access water from aquifers, either building a platform out at sea and drill into the seabed, or drill from the mainland or islands close to the aquifers, it makes sense to repurpose already built oil rigs to obtain the water.
2. Convert oil rigs into artificial reefs

Marine life clings to oil rigs. Diver and co-founder of the government Rig to Reef Exploration Project, Emily Callahan, was stunned when she went diving by an oil rig:
“You’re looking (at) something the size of the Empire State Building, but there’s so much life on it: Anemones, and mussels, and sea lions all around you, and scallops, it looks like it’s breathing, and it’s vibrant. You don’t see a shred of metal underneath it.”
According to the PNAS, oil platforms off California are among the most productive marine fish habitats globally. However critics believe that artificial scaffolding shouldn’t belong in the environment and can potentially catch on fishing nets. They are also concerned that rusting rigs could be toxic to the environment.
