Quantifying the physical demands undertaken by offshore wind technicians during a working day and casualty evacuations.

This article focuses on characterizing the physical demands of offshore wind technicians (WTs) during their typical working day and simulated casualty rescues. Data collected from 14 WTs over three days showed that technicians spent 69% of their time performing moderate physical activity, primarily involving manual handling tasks such as torque and tensioning, with ladder climbing identified as one of the most physically demanding activities. Two simulated rescue scenarios—rescue from the Hub and rescue down the tower ladder—were assessed in five WTs, revealing predominantly aerobic exertion with similar cardiac and metabolic demands, though the Hub rescue elicited higher perceived exertion due to maneuvering in confined spaces. The findings support job task analyses and suggest that key physical requirements for WTs include aerobic capacity sufficient for sustained moderate activity, strength for manual handling, and the ability to work in restricted environments during casualty evacuations.
