Franck Demay, chief executive of Petroineos Refining, said: “For almost a century the Grangemouth refinery has reliably produced high quality fuels for the domestic market and for export.
“We firmly believe that only by taking action now will we preserve one of Scotland’s last large manufacturing sites and a significant contributor to the Scottish economy.”
Petroineos is now entering into a statutory consultation period with workers and trades unions.
Scotland’s Infrastructure Secretary Michael Matheson said: “The Scottish Government recognises that the oil and gas sector has been significantly affected by the impact of the Covid-19 pandemic and its damaging economic consequences, and it is important that Grangemouth has a sustainable future.
“This is an extremely difficult time for most businesses in Scotland and we will do all that we can, within the powers available to us, to help key sectors of our economy recover."
