A conducting engineering corporation in Scotland’s energy industry is understood to be on the verge of announcing in administrators.
BiFab, or Burntisland Fabricators, has two yards in Fife and one at Arnish on the Isle of Lewis.
The firm builds large-scale paraphernalium for the offshore oil and gas industry, as well as scaffolds for offshore wind turbines and tidal generators.
There are currently more than 600 people working at the grounds.
The BBC understands BiFab has had cash flow problems linked to a contract for the Beatrice offshore wind farm in the Moray Firth, and has registered tribunal articles with an intention to go into administration.
