Trade unions have claimed that hundreds of redundancies are imminent at troubled UK fabricator Burntisland Fabrications (BiFab), as work on the Beatrice offshore wind project draws to a close.

The Unite union said it had been informed by BiFab management that redundancy notices will be issued to the core workforce on Tuesday, giving 45 days notice of the closure of the company’s three yards in Fife, Arnish and on the Isle of Lewis.
