The PSA said on Monday that the audit of Teekay Petrojarl and Petrojarl Knarr was done from August 21 to August 30.

The objective of the audit was to assess how Teekay is ensuring compliance with the authorities and its requirements in the maintenance of structures and marine barriers on Knarr.

The safety body stated that two non-conformities were identified relating to the measurement of line tension in the anchoring system and classification of the facilities’ systems and equipment.

The PSA also found improvement points in connection with barriers, verification of weather data, prerequisites for f-year class certificate renewal, gaps in relation to regulations, defective criteria for class notification (DNV GL), and inadequate protection of components in laydown area.

Teekay Petrojarl has to report on how the non-conformities and improvement points will be addressed by November 15, 2019, at the latest.

The Knarr field, operated by Shell, is in the northern sector of the North Sea, around 50 kilometers north-east of Snorre. Knarr has been developed using a production and storage vessel (FPSO), the Petrojarl Knarr, and subsea wells.

Oil is loaded from the Knarr FPSO into tankers, while the gas is exported by pipeline to St. Fergus in the UK. Production from the field began in 2015. The FPSO has a production capacity of 63,000 barrels of oil equivalent per day and a storage capacity of 800,000 barrels.

Although Shell is the operator of the Knarr field, Teekay owns and operates the Petrojarl Knarr FPSO on behalf of the licensees.
