All piping and lay-out standards are now revised

With the initiative taken in 2013, a large number of revision projects were launched. The expert group Piping and Layout, EG-L, are now finalizing their projects, and L-002 and L-004 (edition 2016) are already published and available.

L-001 (current edition 1999) will be approved for publication this fall and L-003 (current edition 1996) will be made available a couple of months later as the enquiry (link to L-003) closes on 10 August. The aim of the revision projects have been to ensure that new experiences on the Norwegian continental shelf, new technologies and the need for cost-saving measures are reflected in the standards. Simplification and cost saving measures have been in focus. Duplicate requirements have been removed.

L-001 has been simplified and is now organised as a generic document to enable projects to generate their own pipe classes. A PED verification of the example pipe classes is included in the references.

L-002 no longer contain requirements for lifting operations. Guidance for use of manual hoses have been included and reduction in man-hours can be obtained by use manual calculations.  

L-003 will reflect current used piping details.

L-004 is simplified and updated with most recent industry practices.

Current status:

  • NORSOK L-001 Piping and valves (new edition: October 2016?)
  • NORSOK L-002 Piping system layout, design and structural analysis (July 2016)
  • NORSOK L-003 Piping details (new edition: December 2016?)
  • NORSOK L-004 Piping fabrication, installation, flushing and testing (July 2016)
  • NORSOK L-005 Compact flanged connections (December 2013)

Standards Norway plans to revise several other NORSOK standards, estimate is 7 others in 2016.

Standards Norway will introduce the portfolio of revised L standards in a breakfast meeting during ONS 2016 on Tuesday August 30.
