Alerts & Learnings Dropped Object Due to Corroded Deluge Flange After landing a lower completion assembly on the drill floor and while retracting the deck crane whip line and twin hook stinger back through the v-door, the twin hook stinger swung to starboard causing one of the hooks to strike a blanking flange on the drill floor deluge line. The 4.95kg blanking flange detached and fell 4.5 metres to the drill floor, landing approximately 1.5 metres from the nearest person. This incident was classified as potential for fatality as per the industry DROPs Calculator. Contributing Factors: The dropped object incident was primarily caused by severe corrosion in the drill floor deluge pipework, exacerbated by a missing support bracket that led to pipe sagging and water accumulation. This corrosion weakened the flange, making it susceptible to impact from the stinger hook. Additionally, the stinger was released in an uncontrolled manner—hooks were not secured or safely guided out—further contributing to the incident.
