RISK MANAGEMENT
OFFSHORE WIND FARMS WHEN LOADS SWING IN THE WIND
Man and materials must regularly overcome around 90 metres in height to access the nacelles of offshore wind turbines for installation, maintenance and servicing activities. Lifting equipment, service lifts and ladders assist in carrying workers, equipment and heavy components.
WHAT ABOUT OCCUPATIONAL HEALTH AND SAFETY?
Lifting and material-handling equipment are used not only onshore for heavy-duty work. They also play a significant part in the installation, servicing, and maintenance of offshore wind turbines far out to sea.
Given this, all wind turbines nowadays come with cutting-edge lifting and material-handling equipment. However, the environmental, ambient, and operating conditions involve specific risks, thus imposing very special requirements on components and occupational health and safety. Workers must be able to get safely from the service boats to the nacelle while safely moving loads that are often very heavy.
OFFSHORE WORK
In concrete terms this means that workers at sea must be able to safely transport say, a hydraulic cylinder with a weight of around 600 kg, even with the boat rocking in high waves, the entire tower swaying in the wind and the loads swinging from the suspension hook.
This gives rise to impact and crush hazards because under these conditions, not even the firm footing already required by accident prevention regulations for manual lifting of lighter loads of up to 25 kilograms can be guaranteed.
