This FOI release comprises an email chain between NOPSEMA and Woodside Energy (Victoria) Pty Ltd, with attached EPA Victoria notifiable incident form NFI-00003791, a monthly recordable report to DEECA, a lost saddle register, and related recovery records. The correspondence concerns NOPSEMA's investigation (IVT14016) into piggyback plastic clamps lost to the marine environment during decommissioning of the Minerva pipeline in the Otway Basin, off Port Campbell, Victoria. Woodside reports an estimated cumulative release of about 186 kg of clamp pieces between January and 2 May 2025, from roughly 4.5 km of pipeline removed (45% complete). Releases are attributed mainly to pipeline cutting and recovery, where stored energy in injection lines reportedly dislodged clamp components. The ENVID workshop had not identified accidental discharge as a hazard. Beach clean-ups are ongoing and a meeting between NOPSEMA and Woodside was proposed for 20 May 2025.
