The North Sea drilling rig on which a fire killed two men last week in a Dundee yard was undergoing only minor maintenance work.
A MacGregor Energy Services spokeswoman said the painting and welding work was due to take 10 14 days.
An investigation by the Tayside police and the Health and Safety Executive, assisted by the rig’s owner, Global Marine, is still trying to establish the fire’s cause.
Police said the two men, a welder and a plater, were declared dead at the scene.
‘Some sort of explosion seems to have resulted in a flash fire,’ said Bill Hamilton, a director of MacGregor.
Fifty firefighters took four hours to put out the blaze in one of the vessel’s legs. Robert Brown, Dundee Fire Brigade deputy fire master, said this was due to access problems rather than the size of the incident.
