Summary
This flash summarises NOPSEMA’s account of a collared eyebolt failure during lifting. Equipment weighing 21.7 tonnes fell 1.2–1.8 m without injuries. Angular loading reduced the eyebolt’s working load limit, while incomplete collar seating imposed shear on its shaft. Ineffective lift planning was identified as a root cause.
