On August 21, the Montara wellhead platform drill rig owned by the publicly traded Thai company PTTEP Australasia suffered a well head accident, resulting in an uncontrolled discharge of oil and gas that continued unchecked until today.
The oil spread through an area known to conservationists as a marine life super-highway, and now covers tens of thousands of square kilometers of turtle, whale, dolphin and fish habitat. "Satellite images tell a shocking story of the spread of over three million liters of oil through this pristine environment," says the Wilderness Society.
Estimates from satellite imagery indicate that the slick has spread over 50,000 square kilometers of ocean. The cost of cleanup has been estimated at over A$5.3 billion.
Now that the fire is out, a safety case revision will be presented to the National Offshore Petroleum Safety Authority to reboard the Montara well head platform to assess the level of damage and to plan for the next phases of the operation. "We do not underestimate the significantly increased technical complexity, logistical challenges and hazards of the work now required in the wake of the damage caused by the fire to the well head platform and the West Atlas rig," said Martins.
