Two fire crews were in attendance after a gas cylinder caught fire in Aberdeen Harbour.
The acetylene canister, which is used for work such as welding, caught fire just before 2pm.
The fire service control room received a call for help and it dispatched two teams from Aberdeen Central Fire Station to the scene on York Street.
Crews used water hoses to put out the flames at the Dales Marine Services industrial yard.
It is not clear what started the fire.
Gordon MacNaughton, who works at the nearby Footdee public toilets, said: “I heard the fire alarm and looked out my front door and see black smoke coming out of the one sheds at 2.15pm.”
There have been no reported injuries.
The fire service workers used two pumps, a jet, and a thermal image camera to put out the fire before leaving the scene at 4.45pm.
Police were in attendance and the road was closed while the incident was ongoing before reopening at 4.40pm.
A police spokeswoman said: “Around 2.15pm on Tuesday, June 13, officers were called to assist emergency services following a fire within a premises on York Street, Aberdeen.
“The road was cleared around 4.40pm.”
Dales Marine Services has been contacted for comment.
