Scotland’s last commercial shipyard Ferguson Shipbuilders in Port Glasgow, Inverclyde, has gone into administration, putting around 80 jobs at risk.
The move by the company was due to the lack of orders and increasing cashflow pressure.
UK trade union Confederation of Shipbuilding and Engineering Unions (CSEU) and GMB, a membership-based organisation that campaigns for workers’ rights, have urged the Scottish Government to intervene and resolve the issue.
GMB Scotland senior organiser and CSEU chair Jim Moohan said: "This is the last remaining commercial shipbuilding yard in Scotland.
"Unless the Scottish Government intervenes this puts the final key in the door of commercial shipbuilding which [has] a history of several hundred years in Scotland.
"Workers with service between 30 and 45 years in that yard have been kicked out without any explanation, now that is a scandal. GMB and CSEU issue a public challenge to the First Minister to meet with ourselves and the conveners in an attempt to retrieve this abysmal situation."
Established in 1902, Ferguson Shipbuilders traded from the Newark Works in Port Glasgow, where it employed 77 workers at the time of administration appointments.
Nimmo said: "Ferguson Shipbuilders is a leading name in the industry with a rich heritage dating back more than 110 years and is the last commercial shipbuilder operating on the River Clyde.
"The Group’s infrastructure and unique offering has earned it global success in recent years, principally from the building of two ‘world first’ diesel hybrid ferries. However, a lack of significant orders and mounting cashflow pressure has led to the group’s inability to continue trading."
Meanwhile, Inverclyde Council leader councillor Stephen McCabe said: "I am shocked by this news about Fergusons but can assure the workforce and community that we will do all that we can to help.
"I am setting up a dedicated task force to support the workforce at Fergusons and to engage with the owners, union and both the Scottish and UK Governments."
Scotland finance secretary John Swinney assured that they will work with the administrators to deliver an integrated service to those losing their jobs.
