The New Zealand Transport Accident Investigation Commission (TAIC) has released its findings on the grounding of the ferry Aratere in Titoki Bay, Picton, on June 21, 2024. The incident occurred when the KiwiRail Interislander ferry, operating on autopilot, made an unintended 34-degree turn toward the shoreline after the pilot engaged the system, expecting a minor three-degree adjustment. The bridge team quickly attempted to regain control but struggled due to unfamiliarity with the newly installed steering system, leading to the vessel grounding.
Fortunately, the Aratere’s watertight integrity remained intact, and it was refloated with the help of harbor tugs within two days. Although the grounding caused damage to the bulbous bow and internal structures, there were no injuries reported. The operator’s failure to fully understand the differences between the old and new steering systems, coupled with inadequate training and safety audits, contributed to the incident.
TAIC’s report outlines four key lessons for workplace safety: assess risks when modifying critical systems, ensure consistent application of communication and navigation procedures, implement quality assurance programs, and clarify responsibilities during safety upgrades. These measures can help prevent similar accidents in the future.
