Summary
Investigation of a dropped grating during coiled-tubing rig-down on Heidrun. A lifted heave compensator struck an open hatch, dislodging a 31-kilogram plate which fell eight metres and grazed a worker’s shoulder. The report examines hatch design, uncorrected damage, lifting arrangements, risk assessment, maintenance and unclear responsibilities through human, technological and organisational analysis.
