This is a 16-slide Woodside Energy presentation to NOPSEMA dated 10 April 2025, titled "Minerva Decommissioning: Engagement with NOPSEMA" and marked confidential. It covers progress on removing the Minerva field infrastructure in Commonwealth and state waters, with pipeline removal at 29% and forecast to run to 2 June 2025. It also covers the EPBC referral for May 2025 work (likely not a controlled action), Victorian DEECA management of change approval, and whale sighting data. A significant concern is the loss of plastic pipeline saddle clamps: about 150 items (roughly 65 kg, or 0.6% of ~10,200 kg) lost to date, with around 70% of the pipeline still on the seabed. Mitigation measures are listed, some still under evaluation. The document also sets out environment plan controls on field joint cuts and debris recovery.
