Scottish fabricator BiFab is to lay off a further 16 staff, according to the GMB union.
GMB said the reason was the wind-down of oil and gas manufacturing work and speculation that a contract from the Neart na Gaoithe offshore wind farm could be delayed until August.
GMB Scotland organiser Hazel Nolan said: “Another score of redundancies were confirmed at BiFab today and the three yards in Fife and Lewis will again be maintained by a skeleton staff by the end of February while we desperately hope for scraps of work from our own billion pound offshore wind developments.”
She said that the Scottish government and clean energy industry group Scottish Renewables should be doing more to protect supply chain jobs.
“The (Scottish) Minister for Energy (Paul Wheelhouse) and the chief executive of Scottish Renewables (Claire Mack) should hold their hands up and admit: ‘We are failing to bring the green jobs revolution to Scotland’,” Nolan said.
