Petroleum & Gas Inspectorate | Alert | No.100 V 1 | 22 April 2022
A winch line counterweight became snagged during rig up operations, causing the steel wire rope to break. The counterweight dropped to the rig floor, resting near the Derrickman. No persons were injured, however, the 5.7kg counterweight landed less than 1m from a rig worker.
The rig crew were observing and monitoring the risk of the Bullhorn becoming entangled as the mast was raised. While raising the mast and observing other known risks, they did not observe the sand line counterweight was caught until the wire rope failed under tension. The counterweight dropped to ground level, narrowly missing a worker.
Investigations are ongoing and further information may be published as it becomes available. The information in this publication is what is known at the time of writing.
We issue Safety Notices to draw attention to the occurrence of a serious incident, raise awareness of risks, and prompt assessment of your existing controls.
