Summary
BSEE investigates crane shock loading during tension-packer setting for well abandonment at Vermilion Block 371 platform A. Shear-ring failure reduced the crane load and stretched its boom cable. Findings address repeated shear-ring use, incorrect rating assumptions, an unsuitable job safety analysis and departure from crane operating requirements.
