“If you find debris which looks similar to the pictures below on the beaches around the neighbouring coast please report it by calling 0333 4141 912.
“Don’t attempt to remove the items yourself, but if you can let us know where you have found it and how much there is, our teams will be along to remove it as quickly as possible. The debris is not harmful but it’s best not to touch it, just to make sure everyone stays accident free.”

Ormonde offshore wind farm lies around six miles off the Cumbria coast in the Irish Sea.
The project, operational since 2011, can generate enough electricity to power 100,000 UK homes.
Ormonde was the first commercial deployment of steel jacket foundations fabricated in Scotland by Bi-Fab.
