Canadian Natural Resources (CNR) has stopped production from its Petrojarl Banff floating production, storage and offloading (FPSO) vessel in the North Sea due to heavy storms.

The vessel is owned by Teekay and reported a loss of tension in two of its anchor lines due to the storms.

Forty-four offshore workers remain were on-board at the time.

"All 44 personnel on-board the FPSO are safe and have been accounted for."

Teekay mobilised the Normand Ranger anchor handling vessel to the site, in addition to two support vessels to assist in the operation.

CNR said in a statement: "All 44 personnel on-board the FPSO are safe and have been accounted for.

"The Petrojarl Banff remains in position under its own power. As a precaution, all production operations have been shutdown."

Following the incident, CNR said it is coordinating with all relevant authorities, including the Coastguard.

The Petrojarl Banff, which is located 190km east of Aberdeen in the Central North Sea, blocks 22/27a and 29/21, has been designed with a storage capacity of 88,000 barrels of oil.

The vessel was delivered in 1997 and has a production capacity of 90,000 barrels of oil per day.

Earlier in December 2011, the FPSO lost its anchors in a storm and was removed from service for turret modification. It came back on stream in July 2014.
