NEGOTIATIONS were continuing last night between the receivers and potential buyers for Birkenhead's Cammell Laird shipyard.
Receivers PricewaterhouseCoopers said it expected to make a further announcement this afternoon.
The yard had been due to be mothballed today but it is now believed that this may not happen until the end of the week.
Further redundancies are, however, likely to be made and by the weekend the only staff remaining will be a handful of care and maintenance workers.
Union officials say they remain hopeful that a buyer will come forward before the yard is closed.
Dave Hulse, GMB shop steward, last night said: "This yard will not shut tomorrow.
"The yard is being reviewed on a daily basis. "The unions are meeting with the receivers tomorrow."
Mr Hulse added: "The management team, I believe, is sincere and genuine and I think it will make an offer and hopefully this will be before the end of the week."
Meanwhile, the finishing touches are currently being added to the four ships remaining at the yard, the Royal Fleet Auxiliary vessels Argus and the Sir Tristram.
The refit of the RFA ship Sir Percivale is also nearing completion, together with the refurbishment of a ferry.
A spokesman for PricewaterhouseCoopers said last night: "The receivers are still in negotiation with interested parties.
"We will be making a further announcement tomorrow afternoon."
Coun Steve Foulkes, leader of Wirral Council, said, if the yard did close, he believed it would reopen very quickly.
He said: "The fact the yard is winding down to such a small level of activity is regretful.
"We remain committed to doing everything we can to assist in the finding of a buyer.
"If the yard does close, we believe the facilities which are there and the skilled workforce will ensure it is not closed for very long. We hope a new buyer will take advantage of the facilities and workers and reopen the yard as soon as possible."
There were no redundancies at the yard last week but a fortnight ago there were 60 job losses.
Just 350 workers now remain compared with a 1,500-strong workforce when the business collapsed into receivership in April.
Receivers remain hopeful that a buyer will be found to reopen Lairds.
Two former Laird's managers are believed to be putting together separate bids to buy the yard - former managing director John Syvret and former financial controller Steve Brookfield.
Laird's went into administration earlier this year as a direct result of a contract dispute with the Italian cruiseline company Costa Crociere.
The company was left £40m out of pocket in November after the Italians walked away from a deal to have the cruise ship Costa Classica lengthened by the insertion of a giant mid-section, which had already been built at the Birkenhead yard.
