Summary
Two workers escaped injury when offshore platform topsides detached and swung above them during decommissioning in Western Australia in 2021. The flash examines inadequately assessed crane auto-tensioning forces and pre-load tension, and outlines technical lift-plan assessment, castellated cuts where rotation is possible, and keeping workers clear of suspended loads.
