Woodside Energy notified NOPSEMA of a dangerous occurrence at the Pyrenees facility on 3 December 2022 when an unloaded 7-tonne crane (Crane No.4) struck a non-directional beacon antenna during scaffold removal operations on the monkey island deck. The 8-metre antenna, used for helicopter navigation in low-visibility conditions, sustained damage to shorter array elements near the whip aerial. While initial function testing indicated the system was operational, signal range was unknown and the antenna required replacement rather than repair. NOPSEMA received notification within 40 minutes of the incident and responded the same day. The incident was classified as a dangerous occurrence under occupational health and safety damage to safety-critical equipment category, escalated to level 1 investigation on 5 December 2022, and an initial report was submitted by the duty holder on the required due date of 6 December 2022.
