Forties pipeline operator Ineos has announced that it has started pressure testing on the structure.
Ineos said “good progress” was being made and that the repair job on the pipeline was mechanically complete.
Ineos confirmed that a small amount of customers are now sending oil and gas through the pipeline at reduced rates to test the flow and pressure.
The energy firm also confirmed it has restarted the Kinneil facility near Grangemouth.
Ineos said in a statement: “It is expected that the precautionary safety cordon will remain at 150m whilst pressure testing continues.
“For the time-being the unclassified CK12 Netherley to Cookney road, which passes close to the site remains closed by the police and all non-essential drivers are being requested to seek alternative routes to ensure that the road remains clear for essential works.”
The 235-mile pipeline system links more than 80 North Sea field to the UK mainland and the Ineos site in Grangemouth, delivering almost 40% of the UK’s North Sea production.
The petrochemicals giant said earlier this month that it had lowered the pressure in the pipeline after identifying a hairline fracture at a site near Netherley, but did not have to shut it down.
But on December 11 Ineos said the crack had got bigger, forcing it into a controlled shutdown.
A number of residents were evacuated from their homes, a road was closed and a cordon was set up after the discovery was made.
