Armour Stones Arrive at Walney Construction Site (UK)

The first load of totally 70,000 tonnes of armour stones for scour protection has arrived at the Walney construction site.

The stones are supplied from the Stainton Quarry and will be used to armour the turbine foundations for scour protection. The stones will be placed in a radius of 15 metres around the turbine foundation and will reduce the potential erosion of sand and material around the monopile caused by the current.

This work is expected to commence at the end of January.
