Windmill blades

We attended a vessel at Grangemouth last week to undertake the welding down of  sea-fastening fixings. The cargo of large windmill blades was loaded by shore side cranes and then secured in position by welding down stoppers to stop the cargo moving and then Dee rings to allow securing chains and lashings to be fitted by the ships crew.

The blades are transported in lifting / supporting frames to ensure the blades are properly supported during transportation around the world, however even when stationary the blades “waggle” around. The blades are generally made from fibre glass with various protrusions moulded into  them to reduce static charges and to stabilise the blade.
