North Sea operator Canadian Natural Resources (CNR) International (UK) has confirmed production was shutdown on its Ninian Central platform on Sunday due to a hydrocarbon release.
The release was discovered at 4:40am and production was halted until 10pm on Sunday evening.
The Ninian Central platform is located in the East Shetland Basin approximately 240 miles north east of Aberdeen.
A spokeswoman for CNR International said in a statement: “CNR International (UK) can confirm that production was shutdown on its Ninian Central Platform after a hydrocarbon release was discovered at 4.40am on Sunday 26th August.
“The release was promptly isolated and production on the platform restarted at 10pm on Sunday 26th August.”
The Ninian Central platform has courted controversy after a number of high-profile incidents.
In May, an incident occurred on the platform when “dispersed oil was discharged to sea”.
A notice was issued by the Offshore Petroleum and Decommissioning Regulator (OPRED), who said it breached environmental regulations.
In 2010, safety chiefs have took action against CNR following a major North Sea gas leak.
The Health and Safety Executive accused CNR International of putting people in danger on the Ninian Central platform and enforced it to comply with a series of maintenance demands.
