AS Norske Shell (Shell) is the operator of the Knarr field, while Teekay owns and operates Petrojarl Knarr. Shell took over operatorship of Knarr from BG Group Norway in February 2016.
From 3 to 6 October 2016, the PSA carried out an audit of how Shell is managing the integrity of flexible risers, transfer lines and associated safety equipment, and of Teekay's activities as production operator.

The audit revealed non-conformities relating to:

- Follow-up of flexible pipelines
In addition, improvement points were detected in connection with
- Labelling of equipment

The companies have been given a deadline of 1 February 2017 to report on how the non-conformities will be dealt with and how the improvement points will be assessed.
Knarr is a field in the northern part of the North Sea, 50 kilometres northeast of the Snorre field. The water depth is 400 metres. Knarr was discovered in 2008, and the plan for development and operation (PDO) was approved in 2011. The development comprises a floating production, storage and offloading vessel (FPSO) and two subsea templates, including six wells for production and injection. The Knarr field consists of two segments, Knarr West and Knarr Central with one template on each structure. Production started in 2015 and ceased in 2022.
