A crane collapse has been blamed for the capsizing of a tanker at Poland's Nauta shiprepair yard.
The 2,700-dwt Hordafor V (built 1997) overturned at the Gdansk plant on Thursday, ABC Nyheter reported.
Firefighters were deployed to the scene to assist with the salvage operation.
No injuries have so far been reported.
The vessel is operated by Norway's Hordafor.
