Summary
Investigation of a crane boom falling 10 metres on Gullfaks B following steel-rope fatigue. The report examines sheave geometry, rope bending, earlier equipment damage and inadequate recognition of the rope’s safety-critical role. It identifies shortcomings in service-life calculations, replacement intervals and visual-only inspection arrangements.
