An offshore installation was awaiting delivery of an urgently needed container. The east crane normally used for such lifts was under repair, so a risk assessment was conducted and the west crane was chosen instead. During the lift of one of the last containers, the load became uncontrollable and fell into the sea. No personnel were injured, but the container's contents may have been damaged. The incident highlighted the importance of following approved lifting plans and maintaining awareness of hazards, even during urgent jobs.
