PTTEP Australasia lawsuit (re Montara oil spill in Indonesia)

In 2016, an Indonesian seaweed farmer filed a class action lawsuit in Australia representing 15,000 farmers against PTTEP Australia. They allege a 2009 oil spill which released thousands of litres of oil into the Timor Sea significantly impacted their highly lucrative seaweed farming industry. The case is ongoing.

On 3 August 2016, Daniel Sanda, an Indonesian seaweed farmer, filed a class action lawsuit in the Federal Court of Australia representing approximately 15,000 farmers, against PTTEP Australasia (PTTEPAA), a subsidiary of a Thai state-owned company. The claim refers to a 2009 blowout at an oil well at the Montara Wellhead Platform in Australia, operated by PTTEPAA, which released thousands of litres of oil and gas into the Timor Sea for about 74 days. 

Alleging that the spill significantly hindered what was otherwise a highly lucrative seaweed farming industry, the plaintiffs claim damages for the immediate destruction of seaweed caused by the spill, as well as the subsequent decline in production caused by oil pollution, leading to loss of their livelihoods. They allege that PTTEPAA, as the operating company of the Montara platform, ought to have reasonably foreseen the risk of harm to property and businesses resulting from such an accident, and from the use of chemical dispersants to mitigate the effects of an oil spill. 

In 2010, the Montara Commission of Inquiry, established by the Australian Government to investigate the incident, assessed that the blowout occurred largely due to the company’s negligence regarding the maintenance of the well. The company pleaded guilty to several breaches of safety regulations. Its operations at Montara continue to this day, although the Australian Government refused permission to drill a new production well planned in Montara. 

The case is on-going and a hearing started in June 2019.
