An 80-metre-long ship, which ran aground near a lighthouse in an important wildlife haven, could remain stuck for another fortnight if it is not shifted, an RNLI spokesman said.
The MV Danio was heading from Perth to Belgium when it got caught on rocks in the Farnes Islands, three miles off the Northumberland coast, at 4.30am on Saturday.
The vessel, carrying timber, was not thought to be badly damaged and there were no reports of any fuel leak after she got stuck on the Blue Caps, close to the Longstone Lighthouse.
Salvagers, the National Trust which looks after the islands and pollution control experts met on Sunday.
Ian Clayton, of Seahouses RNLI, said: “They are waiting for more salvage equipment to be brought in and it is extremely unlikely that there will be any attempt today.
“However, they will be making a determined effort, I suspect, tomorrow evening. If they cannot get it off tomorrow, the chances are it will be stuck for another fortnight.”
Lower tides over the next two weeks would hamper removal attempts.
Hugh Shaw, a Government official overseeing the salvage effort, said more equipment will be brought to the site and a rescue attempt will be made at high tide this evening.
