On 5 April 2024, Woodside Energy reported a notifiable incident (NTF12898) during Griffin Field decommissioning operations in Western Australia where a riser transport module (RTM) toppled over onto the seabed while leaning at a 15-degree angle during preparation works. The RTM sustained deformities in its foam-housing section but no visible openings or surface leaks were observed. However, approximately 900 tonnes of ballast water leaked from the module. NOPSEMA classified the incident as Environment Reportable and escalated it to Level 1 on 10 April 2024. The regulator requested visual footage, photographs, and ballast testing results. Woodside subsequently drilled holes in the RTM to prevent refloating, and submitted its initial report on 17 May 2024, four days after the due date.
