On a drilling rig, a non-magnetic drill collar (NMDC) was lifted from the hydraulic catwalk with a third-party pickup sub. The pickup sub slipped through the elevators. The non-magnetic drill collar slid and bounced out of the trough and landed halfway down the catwalk. There were no injuries.
Ask yourself and your crew:
- How can something like this happen here (e.g. on our site)?
- What safety measures (i.e. procedures, controls/barriers) do we have in place to mitigate the risk?
- How do we know the risk controls/barriers are working?
- What improvements or changes should we make to the procedures, controls/barriers or the way we work?
