This release contains correspondence between NOPSEMA and Woodside Energy concerning a draft investigation report (IVT14016) into plastic saddle clamps lost to the marine environment during decommissioning of the Minerva pipeline in Commonwealth waters. Woodside's 3 June 2025 response disputes the draft's conclusion on non-compliance with the Minerva Decommissioning and Field Management Environment Plan, arguing the saddle losses were appropriately recorded under planned performance standard PS 9.2 and that recording under an unplanned standard would not have changed the timing of action or notification. The material includes Woodside's 10 April 2025 engagement presentation, which reports about 65kg (150 items) of an estimated 10,200kg of saddles lost to date, roughly 0.6 per cent, with around 70 per cent of the pipeline still on the seabed. It also contains Subsea7 incident emails describing repeated saddle losses during cutting and drift modelling of 10,000 items. NOPSEMA's final regulatory outcome is not included.
