The basis for materials selection
The NORSOK Committee has released a new revision, revision 5, of the NORSOK M-001 "Materials selection" standard.
Similarly to ISO 21457, NORSOK M-001 provides guidance and requirements for material selection and corrosion protection for hydrocarbon production and processing facilities as well as supporting systems for fixed offshore installations, including subsea production systems. The standard assumes a minimum of 20 years design life.
Although developed by the Norwegian petroleum industry, NORSOK standards are recognized internationally and used by oil and gas companies and original equipment manufacturers worldwide.
Unfortunately, NORSOK standards are not longer offered free of charge. A copy Revision 5 (in English) can be obtained here.
Update March 10, 2017
Revision 5 has been withdrawn from Standard.no. Revision 4 is the current version of the standard, which can be downloaded here.
