On Saturday, rig workers spotted a ‘sheen’ of gas condensate floating on the ocean’s surface in the Gippsland Basin between Victoria and Tasmania.
The slick came from a leaking gas pipeline belonging to oil and gas giant Esso that had ruptured during the early stages of being shut down—a process known as decommissioning.
This 'sheen' is now travelling through the ocean between Tasmania and Victoria, through the habitat of endangered blue whales and other rare and threatened species.
How did it happen?
The offshore oil and gas developments in this region of Australia are some of the oldest in the country. Rigs and pipelines are rusting, dangerous, and toxic to the marine environment.
Even those being decommissioned—like the pipeline involved in Saturday’s leak—contain traces of petroleum and other hazardous chemicals.
Worryingly, Esso wants to use old oil and gas infrastructure in other parts of the Gippsland Basin for carbon dumping projects, also known as carbon capture and storage (CCS). This would involve pumping concentrated carbon dioxide under the ocean floor.
If a similar pipeline rupture were to happen on a carbon dumping project, the leaking carbon dioxide would acidify the seawater and do untold damage to shellfish and the local marine ecosystem.
Australia’s offshore regulator, NOPSEMA, needs to stop acting as an industry enabler, tighten regulations, and protect our oceans from risky carbon dumping projects.
