What happened
During 2023 a technician became detached from the fall arrest rail while descending a fixed vertical ladder inside the tower of an offshore wind turbine in Europe. The technician regained balance, stopped the descent, secured themselves in a stable position and then investigated what had happened. There were no injuries. The event was published as an anonymised near miss case study by an offshore wind industry incident sharing scheme, which collects high potential events so that operators can learn from them.
Contributing factors
The published case study states that the technician became detached from the safety rail during the descent. It does not give a specific cause for this event. As general context, industry material on climbing inside turbine towers describes several recognised detachment mechanisms: incompatibility between a fall arrest device and the rail where equipment from different manufacturers is combined without verified compatibility, errors in clipping or unclipping, equipment wear or damage, and the device leaving the rail at landing platform transitions. None of these has been attributed to this event by the source.
Lessons learned
- A fall arrest device on a vertical ladder rail can detach during descent. Operators should verify device and rail compatibility at procurement and after any change of equipment type.
- After detachment from a fall arrest rail the technician stopped the descent and secured position before continuing. Operators should train staff to follow this sequence on every climb.
- High potential near misses with no injury still need full investigation. Operators should submit and review anonymised cases so teams learn detachment modes seen elsewhere.
