On 23/2/2001 following repetitive work involving breaking 348 pipe joints and laying singles on the pipe deck, a task to make up a cement stand was commenced. The made up stand was 1.5m higher than a normal drill pipe stand. Once made up, the cement stand was being racked back when the Driller lowered the travelling block. The top of the cement stand got caught on the underside of the gearbox of the travelling equipment causing the cement stand to be driven down into the drill floor (bird bath) where it bowed. Significant potential energy was stored in the cement stand before it whipped across the drill floor striking two men and fatally injuring them.
