FOREWORD
NORSOK (The competitive standing of the Norwegian offshore sector) is the industry initiative to add value, reduce cost and lead time and remove unnecessary activities in offshore field developments and operations. The NORSOK standards are developed by the Norwegian petroleum industry as a part of the NORSOK initiative and are jointly issued by OLF OLF (The Norwegian Oil Industry Industry Association) and TBL (The Federation of Norwegian Engineering Industries). Industries). NORSOK standards are administered by NTS (Norwegian (Norwegian Technology Standards Institution). The purpose of this industry standard is to replace the individual oil company specifications for use in existing and future petroleum industry developments, subject to the individual i ndividual company's review and application. The NORSOK standards make extensive references to international standards. Where relevant, the contents of this standard will be used to provide input to the international standardization process. Subject to implementation into international standards, this NORSOK standard will be withdrawn.

SCOPE
The standard defines the installation requirements for piping details.

TECHNICAL REQUIREMENTS
5.1
General
This document is based upon using components from L-CR-001. However, components not covered in L-CR-001 may be handled as special items. i tems. NORSOK standard

5.2
L-CR-003 Rev. 1, January 1996
Options
This standard contains individual piping details. It is the intention that each project shall compile a set of standard sheets from this document applicable for the particular project. Undesired sheets and options (E.g. 10A or 10B) should be subtracted by the project. 5.3
Double block
Requirements for double block (& bleed if applicable) shall be in accordance with P-CR-001. The details shown in this document have been based on the assumption of applying double block arrangement for ANSI Class 600 and above. 5.4
Modular compact valves
The philosophy for use of modular compact valves will be included when these valves have been included in the next revision of NORSOK standard for Piping and valves, L-CR-001. However, some of the details in this standard show Modular Compact Valves. The extent of use of these valves, is to be decided by project. 5.5
Valve legend
Please note that this standard are not using the NORSOK symbols according to Z-CR-004, CAD legend. The required symbols were not available when this standard was made.

Drilling related piping is not included in this revision. 5.7
Hydraulic
Hydraulic related piping is not included in this revision. 5.8
Birdscreen
Use standard flanges for optional closure solutions during construction. For larger sizes, if no pressure testing is required, consider use of other closure solutions for weight reduction.
