(Adds Statoil comment)
OSLO May 29 Gas leaked on the Heimdal platform
in the North Sea off Norway on May 26 and caused an emergency
evacuation, but the situation was normalised the same day,
operator Statoil said on Tuesday.
The gas leak occurred during the testing of emergency
shutdown valves at the platform, which was not on stream due to
a shutdown for maintenance.
"The leak was identified and stopped, and the situation was
normalized later on Saturday," Statoil's spokesman Ola Anders
Skauby told Reuters.
"It was a serious situation, but the size of the leak has
yet to be established during the investigation," he added.
A Statoil spokesman said the incident would not affect the
ongoing maintenance, but declined to say when the platform was
expected to restart.
Norway's Petroleum Safety Authority will also investigate
the leak, he added.
