Hundreds of jobs are at risk at Harland & Wolff as the shipbuilder is running out of cash, according to the BBC.
The Belfast shipbuilder- which opened a new company in Aberdeen last year to service the energy sector- is understood to be in crisis talks to save it from collapse.
Harland & Wolff Technologies opened in August last year and focuses on fuels of the future, batteries, propulsion and system integration, whilst servicing operational assets in the North Sea.
One union representing the firm is calling for the government to step in as there is "only funding for the business until the end of the month."
The company has been struggling since its shares were suspended in July, after it failed to publish audited accounts.
A review looking at options for the shipyard by Rothschild bank is expected to be finished in the coming weeks.
The GMB union said: "Workers, families, and communities will potentially be thrown into turmoil once again, in just days or weeks, because of abject failure in national industrial strategy and corporate mismanagement."
Harland & Wolff currently employs 1,500 people and has yards in Belfast, Devon and Scotland.
