Emergency engineers have said plans to pump heavy mud into the pipeline leaking gas on board a North Sea platform can go ahead.
A team from operators Total flew out to inspect the leak on Thursday.
They said there was no "showstopper" for the "dynamic kill" plan to plug the Elgin platform well with mud.
Total has also released the first picture which shows the gas leaking from four points on a wellhead at the installation.
It comes as a Scottish government marine research vessel has set sail to carry out a four-day environmental assessment at the site.
Marine Scotland, Sepa, the Health and Safety Executive and Scottish Natural Heritage are among the bodies involved.
