NORSOK L-001:2017 was adopted as a NORSOK Standard in January 2017. It replaces the 1999 edition.
This standard should be seen in conjunction with other NORSOK standards for design, construction and installation of piping and systems. This fourth edition has, to a large extent, been simplified compared to previous edition. Projects shall develop pipe class sheets and valve data sheets to suit actual conditions, based on guidelines and requirements in this standard. The main focus is to establish simple, robust and cost efficient solutions.
The most frequently used piping classes are given as example sheets in Annex A. Material master sheets are included in Annex B and element datasheets ar found in Annex C. Active links to complementary documents such as the NORSOK weldolet guidelines in Annex D and the 2014/68/EU (PED) verification of revision 4 (2017) in Annex E are only available in the electronic version of the standard.
