Quantifying the essential tasks of offshore wind technicians.

Background: Offshore wind technicians (WTs) have been identified as having an occupation with varying physical demands. Therefore, in order to assess WTs capability to undertake the job, there was a need to identify and quantify the physical requirements of the essential tasks.

Objective: To establish the essential tasks and quantify the associated minimum physical demands of being an offshore WT.

Methods: Wind Farm organisations (n = 10) across five countries, undertook a multi-modal observational approach comprising of semi-structured interviews (n = 45), focus groups (n = 14), survey (n = 167). In addition, observations, objective measurements, video footage and standard operating procedures were reviewed. A service campaign was broken down into component tasks, and analysed in terms of technical specifications, e.g. equipment, frequency, duration, rest breaks, clothing ensembles, and the methods of best practice for undertaking each of the tasks. Task descriptions were produced and minimum performance standards recommended.

Results: The job tasks associated with WTs can be broken down into two categories and five areas of work (Essential infrequent = casualty evacuation and prolonged ladder climbing; Essential frequent = short ladder climbs, manual handling and working in restricted spaces).

Conclusions: The results presented constitute work carried out in Phases 1 and 2 of a three phased work programme to establish a physical employment standard required by WTs working in offshore wind. These findings will underpin the development of a minimum performance standard for the global offshore wind industry.
