Production has been restored at three North Sea platforms which were shut down due to pipeline repairs.
Repsol Sinopec Resources UK (RSRUK) announced two weeks ago that it was working to repair an issue with the main export pipeline from the Claymore platform to the Flotta oil terminal in Orkney.
Production was also halted from the operator’s Tartan platform and Cnooc’s Golden Eagle installation, which both flow through the same export line.
A temporary repair has now been made with production now being restored from the platforms.
Further maintenance work will take place during a planned summer shutdown of the Claymore.
RSRUK said the issue related to a leak of hydraulic fluid, not oil, so there was no risk of a hydrocarbon leak.
A spokesman for the firm said: “The situation has been temporarily resolved, pending further work being completed during our planned summer shutdown.”
Claymore lies around 100miles north-east of Aberdeen.
Last month, RSRUK announced plans to extract 10million additional barrels of oil from the Claymore, Tartan and Piper Bravo installations.
