Further talks are due to take place on the future of the Arnish renewable energy yard in the Western Isles.
Camcal was involved in the Beatrice offshore wind farm project
Last month, operator Camcal - which builds towers for wind farms and wave machines at Arnish - announced it was laying off 50 of its 90 workers.
The firm, which has been struggling with financial difficulties, hopes it could be saved by a company buy-out.
Monday's discussions with an unnamed potential investor are seen as being crucial to its survival.
Camcal chairman James MacCallum said: "We should have a clearer idea over the future of the yard by the middle of the week."
There are fears that the company could be placed into administration if a takeover cannot be agreed.
The yard's sole remaining order is to manufacture 16 wind towers for Dutch firm EWT.
It has recently been involved in the construction of two of the world's biggest offshore wind turbines for the Beatrice Field in the Moray Firth and a large tower for a turbine in Germany.
