PSA Inspects Knarr FPSO

The Petroleum Safety Authority (PSA) Norway has carried out an audit of Shell’s management of the integrity of flexible risers, transfer lines and associated safety equipment on Knarr FPSO.

Knarr is located in the North Sea west of Måløy, approximately 50 kilometers north-east of Snorre.

It has been developed using subsea wells and a floating production unit, Petrojarl Knarr FPSO.

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.

AS Norske Shell (Shell) is the operator of the field, while Teekay owns and operates Petrojarl Knarr.

The audit revealed non-conformities relating to:

  • Overpressure protection of gas export pipeline,
  • Follow-up of overpressure protection performance requirements,
  • Passive fire protection,
  • Follow-up of flexible pipelines.

In addition, improvement points were detected in connection with

  • Labelling of equipment,
  • Follow-up and verification,
  • Maintenance management.

The companies have been given a deadline of February 01, 2017, to report on how the non-conformities will be dealt with and how the improvement points will be assessed.
