A preliminary report by the Australian Transport Safety Bureau (ATSB) has shed light on the grounding incident involving the RSV Nuyina, Australia’s Antarctic research icebreaker, which occurred on October 13, 2025. Initially described by Serco and the Australian Antarctic Division as minor seabed contact, the report confirms that the vessel briefly grounded near Heard Island while conducting drone surveys about 4,000 kilometers southwest of Perth.
During its operations near Fur Seal Beach, the Nuyina came into contact with both its retractable drop keel and hull, leading to a more detailed sequence of events. The drop keel, equipped with scientific instruments, was extended approximately 75 centimeters below the vessel’s nominal draft. However, the navigational echo sounders were turned off to avoid interference with the multi-beam system, which remained active and gathered depth data that was not visible on the vessel’s electronic chart display.
The incident unfolded as the ship repositioned following survey activities. While the captain planned the route using the aft ECDIS station, this information was not displayed on the forward navigation system. As the situation progressed, alerts indicated decreasing water depth, leading the crew to attempt corrective maneuvers. However, the Nuyina ultimately grounded but quickly freed itself with minimal hull damage. Following consultations, the vessel continued its Antarctic mission before returning to Hobart. The ATSB report remains preliminary and does not include findings, with further investigation into safety measures ongoing.
