"Positive discussions" have been held regarding the sale of Belfast shipyard Harland and Wolff, according to the administrators.
The business, BBC News reports, entered administration earlier this month, with accountancy firm BDO overseeing the process.
The move places 120 jobs at risk and could spell the end of the firm, best known for building the Titanic.
BDO said it hoped the ongoing talks may lead to "credible offers".
"In light of this, the administrators, in tandem with the unions and workforce, are intending to continue the unpaid temporary lay-off initiated on our appointment beyond today," it added.
"The limited retained team of workers are continuing to maintain the site and assist the administrators in carrying out their duties."
