This Woodside Energy file note, dated 28 March 2025, sets out an internal engineering assessment for decommissioning the Minerva field's 10km offshore pipeline. It was prepared to satisfy Performance Standard 9.1 of the Commonwealth and State environment plans, which requires reasonable assurance that plastic debris (such as coating or saddles) will not be released when pipeline field joints are cut. The note reports two carbon steel trial cuts on the Seven Sisters vessel, on 17 and 27 March, with the first described as inconclusive, and a duplex pipe trial. One observation records that no coating material separated during an unsuccessful excavator cut. The note concludes that field joint cuts will release the same or less plastic debris than cuts through the concrete section, and recommends field joint cutting as the preferred option. The document contains no regulator decision or enforcement action.
